  • Python: Matching & Stripping port number from socket data

    - by tobywuk
    Hello, I have data coming in to a python server via a socket. Within this data is the string '<port>80</port>' or which ever port is being used. I wish to extract the port number into a variable. The data coming in is not XML, I just used the tag approach to identifying data for future XML use if needed. I do not wish to use an XML python library, but simply use something like regexp and strings. What would you recommend is the best way to match and strip this data? I am currently using this code with no luck: p = re.compile('<port>\w</port>') m = p.search(data) print m Thank you :)

  • How does * work in Python

    - by Deqing
    Just switched from C++ to Python, and found that sometimes it is a little hard to understand ideas behind Python. I guess, a variable is a reference to the real object. For example, a=(1,2,5) meaning a - (1,2,5), so if b=a, then b and a are 2 references pointing to the same (1,2,5). It is a little like pointers in C/C++. If I have: def foo(a,b,c): print a,b,c a=(1,3,5) foo(*a) What does * mean here? Looks like it expands tuple a to a[0], a[1] and a[2]. But why print(*a) is not working while print(a[0],a[1],a[2]) works fine?

  • Python in Finance by Yuxing Yan, Packt Publishing Book Review

    - by Compudicted
    Originally posted on: http://geekswithblogs.net/Compudicted/archive/2014/06/04/python-in-finance-by-yuxing-yan-packt-publishing-book-review.aspx I picked Python in Finance from Packt Publishing to review expecting to bore myself with complex algorithms and senseless formulas while seeing little actual Python in action, indeed at 400 pages plus it may seem so. But, it turned out to be quite the opposite. I learned a lot about practical implementations of various Python modules as SciPy, NumPy and several more, I think they empower a developer a lot. No wonder Python is on the track to become a de-facto scientist language of choice! But I am not going to compromise the truth, the book does discuss numerous financial terms, many of them, and this is where the enormous power of this book is coming from: it is like standing on the shoulders of a giant. Python is that giant - flexible and powerful, yet very approachable. The TOC is very detailed thanks to Packt, any one can see what financial algorithms are covered, I am only going to name a few which I had most fun with (though all of them are covered in enough details): Fama*, Fat Tail, ARCH, Monte-Carlo and of course the volatility smile! I am under an impression this book is best suited for students in Finance, especially those who are about to join the workforce, but I suspect the material in this book is very well suited for mature Financists, an investor who has some programming skills and wants to benefit from it, or even a programmer, or a mathematician who already knows Python or any other language, but wants to have fun in Quantitative Finance and earn a few buck! Pure fun, real results, tons of practical insight from reading data from a file to downloading trade data from Yahoo! Lastly, I need to complement Yuxing – he is a talented teacher, this book could not be what it is otherwise. It is a 5 out of 5 product. Disclaimer: I received a  free copy of this book for review purposes from the publisher.

  • Trouble with Wubi and dual boot install

    - by noam
    Is there a difference between wubi install and doing an install of Ubuntu alongside windows7? I ask because I used wubi, but I'm having trouble with certain things like being unable to change my brightness settings and I'm wondering if installing from a usb drive would change anything. Also, I've tried to do a usb drive install, but it doesn't give me the option to install alongside, it only shows the "Replace Windows 7" and "something else" options. Is this because I already did a wubi install?

  • Install app on Motorola Backflip from AT&T

    - by eric
    I'm trying to test an app out on the Motorola Backflip with AT&T as the carrier. I checked USB debugging on the phone's Development screen. Using Eclipse, how do I get the app to load on the Backflip so I can test it? DDMS shows a device with a bunch of question marks and unkown. Seems that it only gives me the option to load the app on the SD card which doesn't do me any good. I searched and found a Motorola driver which I'm supposed to install to the adb folder. Where is that folder? I've checked the phone and on my development machine. Maybe I need new glasses?

  • Install .exe software application on remote machines.

    - by coral_reef
    Hi, I modified this script from the net, which is suppose to install .exe applications for remote machines: $m = Read-Host "Enter machine name" $File = "c:\temp\office2007sp2-kb958194-fullfile-en-us.exe" $product = [WMICLASS]"\$m\ROOT\CIMV2:win32_Process" $product.Create($File) When I run this script, I have noticed that this program promptly creates a process in the remote machine with the application name office2007sp2-kb958194-fullfile-en-us.exe. This can be checked in the task manager also. But other than that, there is no way to find out if this is getting installed in the remote machine or not. Is there a way to find out, if the installation is really happening? Or does this script actually works? Any help will be great! Reagrds Arindam

  • Cinnamon is broken after upgrade to 13.10

    - by user2306488
    I see reports of people with Unity broken after upgrading to 13.10. In my case Unity works fine but cinnamon is broken. It opens the startup applications but no window manager, no menus and the keyboad shortcuts won't work. As a consequence I can't even log out or shut down cleanly.

  • tkinter frame does not show on startup

    - by Jzz
    this is my first question on SO, so correct me please if I make a fool of myself. I have this fairly complicated python / Tkinter application (python 2.7). On startup, the __init__ loads several frames, and loads a database. When that is finished, I want to set the application to a default state (there are 2 program states, 'calculate' and 'config'). Setting the state of the application means that the appropriate frame is displayed (using grid). When the program is running, the user can select a program state in the menu. Problem is, the frame is not displayed on startup. I get an empty application (menu bar and status bar are displayed). When I select a program state in the menu, the frame displays as it should. Question: What am I doing wrong? Should I update idletasks? I tried, but no result. Anything else? Background: I use the following to switch program states: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.config_frame.grid_forget() except: pass try: self.tidal_calculations_frame.grid_forget() except: pass try: self.tidal_grapth_frame.grid_forget() except: pass if state == "calculate": print "Switching to calculation mode" self.tidal_calculations_frame.grid() #frame is preloaded self.tidal_calculations_frame.fill_data(routes=self.routing_data.routes, deviations=self.misc_data.deviations, ship_types=self.misc_data.ship_types) self.tidal_grapth_frame.grid() self.program_state = "calculate" elif state == "config": print "Switching to config mode" self.config_frame = GUI_helper.config_screen_frame(self, self.user) #load frame first (contents depend on type of user) self.config_frame.grid() self.program_state = "config" I understand that this is kind of messy to read, so I simplified things for testing, using this: def set_program_state(self, state): '''sets the program state''' #try cleaning all the frames: try: self.testlabel_1.grid_forget() except: pass try: self.testlabel_2.grid_forget() except: pass if state == "calculate": print "switching to test1" self.testlabel_1 = tk.Label(self, text="calculate", borderwidth=1, relief=tk.RAISED) self.testlabel_1.grid(row=0, sticky=tk.W+tk.E) elif state == "config": print "switching to test1" self.testlabel_2 = tk.Label(self, text="config", borderwidth=1, relief=tk.RAISED) self.testlabel_2.grid(row=0, sticky=tk.W+tk.E) But the result is the same. The frame (or label in this test) is not displayed at startup, but when the user selects the state (calling the same function) the frame is displayed. UPDATE the sample code in the comments (thanks for that!) pointed me in another direction. Further testing revealed (what I think) the cause of the problem. Disabling the display of the status bar made the program work as expected. Turns out, I used pack to display the statusbar and grid to display the frames. And they are in the same container, so problems arise. I fixed that by using only pack inside the main container. But the same problem is still there. This is what I use for the statusbar: self.status = GUI_helper.StatusBar(self.parent) self.status.pack(side=tk.BOTTOM, fill=tk.X) And if I comment out the last line (pack), the config frame loads on startup, as per this line: self.set_program_state("config") But if I let the status bar pack inside the main window, the config frame does not show. Where it does show when the user asks for it (with the same command as above).

  • Dynamically loading modules in Python (+ multi processing question)

    - by morpheous
    I am writing a Python package which reads the list of modules (along with ancillary data) from a configuration file. I then want to iterate through each of the dynamically loaded modules and invoke a do_work() function in it which will spawn a new process, so that the code runs ASYNCHRONOUSLY in a separate process. At the moment, I am importing the list of all known modules at the beginning of my main script - this is a nasty hack I feel, and is not very flexible, as well as being a maintenance pain. This is the function that spawns the processes. I will like to modify it to dynamically load the module when it is encountered. The key in the dictionary is the name of the module containing the code: def do_work(work_info): for (worker, dataset) in work_info.items(): #import the module defined by variable worker here... # [Edit] NOT using threads anymore, want to spawn processes asynchronously here... #t = threading.Thread(target=worker.do_work, args=[dataset]) # I'll NOT dameonize since spawned children need to clean up on shutdown # Since the threads will be holding resources #t.daemon = True #t.start() Question 1 When I call the function in my script (as written above), I get the following error: AttributeError: 'str' object has no attribute 'do_work' Which makes sense, since the dictionary key is a string (name of the module to be imported). When I add the statement: import worker before spawning the thread, I get the error: ImportError: No module named worker This is strange, since the variable name rather than the value it holds are being used - when I print the variable, I get the value (as I expect) whats going on? Question 2 As I mentioned in the comments section, I realize that the do_work() function written in the spawned children needs to cleanup after itself. My understanding is to write a clean_up function that is called when do_work() has completed successfully, or an unhandled exception is caught - is there anything more I need to do to ensure resources don't leak or leave the OS in an unstable state? Question 3 If I comment out the t.daemon flag statement, will the code stil run ASYNCHRONOUSLY?. The work carried out by the spawned children are pretty intensive, and I don't want to have to be waiting for one child to finish before spawning another child. BTW, I am aware that threading in Python is in reality, a kind of time sharing/slicing - thats ok Lastly is there a better (more Pythonic) way of doing what I'm trying to do? [Edit] After reading a little more about Pythons GIL and the threading (ahem - hack) in Python, I think its best to use separate processes instead (at least IIUC, the script can take advantage of multiple processes if they are available), so I will be spawning new processes instead of threads. I have some sample code for spawning processes, but it is a bit trivial (using lambad functions). I would like to know how to expand it, so that it can deal with running functions in a loaded module (like I am doing above). This is a snippet of what I have: def do_mp_bench(): q = mp.Queue() # Not only thread safe, but "process safe" p1 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p2 = mp.Process(target=lambda: q.put(sum(range(10000000)))) p1.start() p2.start() r1 = q.get() r2 = q.get() return r1 + r2 How may I modify this to process a dictionary of modules and run a do_work() function in each loaded module in a new process?

  • python socket related question.

    - by paul
    Hello,All im totally new to socket programming in python. i was read some tutorial and manual, but i didn't found what i want to make python related socket script in manual or tutorial. i want to make socket script which can send some info to server and also receive some info from server. For example, i want to send my login information to server, and want to receive result reply from server. but i have no idea..how to send my login information(id and password) to server. i was captured with wireshark, some process to send login info to server. and i was found port number is 5300 and server ip is 58.225.56.152 and i was send id is 'aaaaaaa' and password 'bbbbbbb' and i was received 'USER NOT FOUND' result from server. how can i make this kind of process with python socket ? if anyone help me some reference or some example or anything help much appreciate! 0000 00 50 56 f2 c8 cc 00 0c 29 a8 f8 c0 08 00 45 00 .PV.....).....E. 0010 00 e2 2a 19 40 00 80 06 d0 55 c0 a8 cb 85 3a e1 ..*[email protected]....:. 0020 38 98 05 f3 15 9a b9 86 62 7b 0d ab 0f ba 50 18 8.......b{....P. 0030 fa f0 26 14 00 00 50 54 3f 09 a2 91 7f 13 00 00 ..&...PT?....... 0040 00 1f 14 00 02 00 00 00 00 00 00 00 07 00 00 00 ................ 0050 61 61 61 61 61 61 61 50 54 3f 09 a2 91 7f 8b 00 aaaaaaaPT?...... 0060 00 00 1f 15 00 08 00 00 00 07 00 00 00 61 61 61 .............aaa 0070 61 61 61 61 07 00 00 00 62 62 62 62 62 62 62 01 aaaa....bbbbbbb. 0080 00 00 00 31 02 00 00 00 4b 52 0f 00 00 00 31 39 ...1....KR....19 0090 32 2e 31 36 38 2e 32 30 33 2e 31 33 33 30 00 00 2.168.203.1330.. 00a0 00 4d 69 63 72 6f 73 6f 66 74 20 57 69 6e 64 6f .Microsoft Windo 00b0 77 73 20 58 50 20 50 72 6f 66 65 73 73 69 6f 6e ws XP Profession 00c0 61 6c 20 53 65 72 76 69 63 65 20 50 61 63 6b 20 al Service Pack 00d0 32 14 00 00 00 31 30 30 31 33 30 30 35 33 31 35 2....10013005315 00e0 37 38 33 37 32 30 31 32 33 03 00 00 00 34 37 30 783720123....470 0000 00 0c 29 a8 f8 c0 00 50 56 f2 c8 cc 08 00 45 00 ..)....PV.....E. 0010 00 28 ae 37 00 00 80 06 8c f1 3a e1 38 98 c0 a8 .(.7......:.8... 0020 cb 85 15 9a 05 f3 0d ab 0f ba b9 86 63 35 50 10 ............c5P. 0030 fa f0 5f 8e 00 00 00 00 00 00 00 00 .._......... 0000 00 0c 29 a8 f8 c0 00 50 56 f2 c8 cc 08 00 45 00 ..)....PV.....E. 0010 00 4c ae 38 00 00 80 06 8c cc 3a e1 38 98 c0 a8 .L.8......:.8... 0020 cb 85 15 9a 05 f3 0d ab 0f ba b9 86 63 35 50 18 ............c5P. 0030 fa f0 3e 75 00 00 50 54 3f 09 a2 91 7f 16 00 00 ..>u..PT?....... 0040 00 1f 18 00 01 00 00 00 0e 00 00 00 55 73 65 72 ............User 0050 20 4e 6f 74 20 46 6f 75 6e 64 Not Found

  • Has anyone ever had OpenCV work with Python 2.7 on MacOS 10.6?

    - by ?????
    I've been trying on and off for the past 6 months to get OpenCV to work with Python on MacOS. Every time there's a new release, I try again and fail. I've tried both 64-bit and 32-bit, and both the xcode gcc and gcc installed via macports. I just spend the past two days on it, hopeful that the latest OpenCV release, that appears to include Python support directly would work. It doesn't. I've also tried and failed to use this: http://code.google.com/p/pyopencv/ I've been using OpenCV with C++ or Microsoft C++/CLI for the past few years, but I'd love to use it with Python on a Mac because that is my primary development environment. I'd love to hear from anyone who's actually been able to get the opencv python examples to run under Mac OS 10.6, either 32 or 64-bit. My last attempt was to follow the instructions on this page http://recursive-design.com/blog/2010/12/14/face-detection-with-osx-and-python/ with a clean, fresh install of 10.6 on a 64-bit capable Mac. My PYTHONPATH is set, and I can see the cv library in it. But an "import cv" from python fails. Previously, the closest I've ever gotten (again, staring on a clean, fresh 10.6 install) was this: Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import cv Fatal Python error: Interpreter not initialized (version mismatch?) Abort trap thrilllap-2:~ swirsky$ I've seen a lot of folks answering similar questions here, but have never seen an definitive answer for it.

    - by Sean Ochoa
    Hello all. I'm trying to create a custom TCP stack using Python 2.6.5 on Windows 7 to serve valid http page requests on port 80 locally. But, I've run into a snag with what seems like Windows 7 tightened up security. This code worked on Vista.

  • Python 3 with the range function

    - by Leif Andersen
    I can type in the following code in the terminal, and it works: for i in range(5): print(i) And it will print: 0 1 2 3 4 as expected. However, I tried to write a script that does a similar thing: print(current_chunk.data) read_chunk(file, current_chunk) numVerts, numFaces, numEdges = current_chunk.data print(current_chunk.data) print(numVerts) for vertex in range(numVerts): print("Hello World") current_chunk.data is gained from the following method: def read_chunk(file, chunk): line = file.readline() while line.startswith('#'): line = file.readline() chunk.data = line.split() The output for this is: ['OFF'] ['490', '518', '0'] 490 Traceback (most recent call last): File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 88, in execute load_off(self.properties.path, context) File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 68, in load_off for vertex in range(numVerts): TypeError: 'str' object cannot be interpreted as an integer So, why isn't it spitting out Hello World 490 times?

    class A(object): def __init__(self, a, b, c): #super(A, self).__init__() super(self.__class__, self).__init__() class B(A): def __init__(self, b, c): print super(B, self) print super(self.__class__, self) #super(B, self).__init__(1, b, c) super(self.__class__, self).__init__(1, b, c) class C(B): def __init__(self, c): #super(C, self).__init__(2, c) super(self.__class__, self).__init__(2, c) C(3) In the above code, the commented out __init__ calls appear to the be the commonly accepted "smart" way to do super class initialization. However in the event that the class hierarchy is likely to change, I have been using the uncommented form, until recently. It appears that in the call to the super constructor for B in the above hierarchy, that B.__init__ is called again, self.__class__ is actually C, not B as I had always assumed. Is there some way in Python-2.x that I can overcome this, and maintain proper MRO when calling super constructors without actually naming the current class?

  • sys.stdout not reassigning to sys.__stdout__

    - by Vince
    I'm pretty new to Python so I am still just learning the language. One of the things I came across was reassigning sys.stdout to change the default output of print. So I wrote this as a test: import sys sys.stdout = open('log.txt','a') print('hey') sys.stdout.close() sys.stdout = sys.__stdout__ print('hi') Now the string 'hi' is not written to the file but it does not show in the default output either. When I assign some other variable to sys.stdout in the beginning and change it back it works, but I'm just wondering why its not changing back the first time.

  • object won't die (still references to it that I can't find)

    - by user288558
    I'm using parallel-python and start a new job server in a function. after the functions ends it still exists even though I didn't return it out of the function (I used weakref to test this). I guess there's still some references to this object somewhere. My two theories: It starts threads and it logs to root logger. My questions: can I somehow findout in which namespace there is still a reference to this object. I have the weakref reference. Does anyone know how to detach a logger? What other debug suggestions do people have? here is my testcode: def pptester(): js=pp.Server(ppservers=nodes) js.set_ncpus(0) fh=file('tmp.tmp.tmp','w') tmp=[] for i in range(200): tmp.append(js.submit(ppworktest,(),(),('os','subprocess'))) js.print_stats() return weakref.ref(js) thanks in advance Wolfgang

  • How to structure Python package that contains Cython code

    - by Craig McQueen
    I'd like to make a Python package containing some Cython code. I've got the the Cython code working nicely. However, now I want to know how best to package it. For most people who just want to install the package, I'd like to include the .c file that Cython creates, and arrange for setup.py to compile that to produce the module. Then the user doesn't need Cython installed in order to install the package. But for people who may want to modify the package, I'd also like to provide the Cython .pyx files, and somehow also allow for setup.py to build them using Cython (so those users would need Cython installed). How should I structure the files in the package to cater for both these scenarios? The Cython documentation gives a little guidance. But it doesn't say how to make a single setup.py that handles both the with/without Cython cases.

  • Problem simulating a key press on Python for Symbian platform on a Nokia 5th ed phone

    - by abhishekbhardwaj007
    I am developing an app for Nokia 5800 Music Express (S60 5th edition) using PyS60 (Python for S60) ,I want to simulate a KeyPress say if a message comes,I detect a message and Press a Key. There does exist a Keypress module for PyS60 for 2nd edition phones which allows this. However I have not been able to install it on my 5th ed phone. Is this module portable? If yes then how do I install it (I get certificate error) and If no then any alternatives for simulating a key press on a 5th edition touch phone?

  • fd.seek() IOError: [Errno 22] Invalid argument

    - by Julian Kessel
    My Python Interpreter (v2.6.5) raises the above error in the following codepart: fd = open("some_filename", "r") fd.seek(-2, os.SEEK_END) #same happens if you exchange the second arg. w/ 2 data=fd.read(2); last call is fd.seek() Traceback (most recent call last): File "bot.py", line 250, in <module> fd.seek(iterator, os.SEEK_END); IOError: [Errno 22] Invalid argument The strange thing with this is that the exception occurs just when executing my entire code, not if only the specific part with the file opening. At the runtime of this part of code, the opened file definitely exists, disk is not full, the variable "iterator" contains a correct value like in the first codeblock. What could be my mistake? Thanks in advance

  • Yield only as many are required from a generator

    - by Matt Joiner
    I wish to yield from a generator only as many items are required. In the following code a, b, c = itertools.count() I receive this exception: ValueError: too many values to unpack I've seen several related questions, however I have zero interest in the remaining items from the generator, I only wish to receive as many as I ask for, without providing that quantity in advance. It seems to me that Python determines the number of items you want, but then proceeds to try to read and store more than that number. How can I yield only as many items as I require, without passing in how many items I want?
