• "Passing Go" in a (python) date range

  - by anonymous coward

  The Rules: An employee accrues 8 hours of Paid Time Off on the day after each quarter. Quarters, specifically being: Jan 1 - Mar 31 Apr 1 - Jun 30 Jul 1 - Sep 30 Oct 1 - Dec 31 The Problem Employees will use an automated system to request paid time off, possibly occurring in the past, as well as the future. Requests should only be accepted if the employee has (or will have) that time available. For instance, if an employee only has 1 Day of Paid Time Off currently available (currently being January 20th), but is requesting 2 Days of Paid Time Off, beginning September 20th, the system should take into account that the employee would have accrued enough time off by then and allow the request. (Obviously ignoring that the employee may use up existing time before that date). I'm currently using Python, and wondering what the correct approach to something like this would be. I'm assuming that using DateTime objects, and possibly the dateutil module, would help here, but my brain isn't wrapping around this problem for some reason.

• Python: UTF-8 problems (again...)

  - by blahblah

  I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.

• TCP Scanner Python MultiThreaded

  - by user1473508

  I'm trying to build a small tcp scanner for a netmask. The code is as follow: import socket,sys,re,struct from socket import * host = sys.argv[1] def RunScanner(host): s = socket(AF_INET, SOCK_STREAM) s.connect((host,80)) s.settimeout(0.1) String = "GET / HTTP/1.0" s.send(String) data = s.recv(1024) if data: print "host: %s have port 80 open"%(host) Slash = re.search("/", str(host)) if Slash : netR,_,Wholemask = host.partition('/') Wholemask = int(Wholemask) netR = struct.unpack("!L",inet_aton(netR))[0] for host in (inet_ntoa(struct.pack("!L", netR+n)) for n in range(0, 1<<32-Wholemask)): try: print "Doing host",host RunScanner(host) except: pass else: RunScanner(host) To launch : python script.py 10.50.23.0/24 The problem I'm having is that even with a ridiculous low settimeout value set, it takes ages to cover the 255 ip addresses since most of them are not assigned to a machine. How can i make a way faster scanner that wont get stuck if the port is close.MultiThreading ? Thanks !

• python: creating a list inside a dictionary

  - by user1871081

  I just started using python and I'm trying to create a program that will read a file that looks like this: AAA x 111 AAB x 111 AAA x 112 AAC x 123 ... the file is 50 lines long and I'm trying to make the letters into keys in a dictionary and the numbers lists that correspond with the keys. I want the output to look like this: {AAA: ['111', '112'], AAB: ['111'], AAC: [123], ...} This is what I've tried file = open("filename.txt", "r") readline = file.readline().rstrip() while readline!= "": list = [] list = readline.split(" ") j = list.index("x") k = list[0:j] v = list[p + 1:] d = {} if k in d == False d[k] = [] d[k].append(v) else d[k].append(v) readline = file.readline().rstrip() I keep getting syntax errors on my if statement and I can't figure out what I've done wrong.

• fastest way to perform string search in general and in python

  - by Rkz

  My task is to search for a string or a pattern in a list of documents that are very short (say 200 characters long). However, say there are 1 million documents of such time. What is the most efficient way to perform this search?. I was thinking of tokenizing each document and putting the words in hashtable with words as key and document number as value, there by creating a bag of words. Then perform the word search and retrieve the list of documents that contained this word. From what I can see is this operation will take O(n) operations. Is there any other way? may be without using hash-tables?. Also, is there a python library or third party package that can perform efficient searches?

  - by user553131

  I have following string. DATE: 12242010Key Type: Nod32 Anti-Vir (30d trial) Key: a5B2s-sH12B-hgtY3-io87N-srg98-KLMNO I need to create dictionary so it would be like { "DATE": "12242010", "Key Type": "Nod32 Anti-Vir (30d trial)", "Key": "a5B2s-sH12B-hgtY3-io87N-srg98-KLMNO" } The problem is that string is unformatted DATE: 12242010Key Type: Nod32 Anti-Vir (30d trial) there is no space after Date before Key Type also it would be nice to have some validation for Key, eg if there are 5 chars in each box of key and number of boxes I am a beginner in python and moreover in regular expressions. Thanks a lot.

• Python and object/class attrs - what's going on?

  - by digitala

  Can someone explain why Python does the following? >>> class Foo(object): ... bar = [] ... >>> a = Foo() >>> b = Foo() >>> a.bar.append(1) >>> b.bar [1] >>> a.bar = 1 >>> a.bar 1 >>> b.bar [1] >>> a.bar = [] >>> a.bar [] >>> b.bar [1] >>> del a.bar >>> a.bar [1] It's rather confusing!

• Python - How can I make this code asynchronous?

  - by dave

  Here's some code that illustrates my problem: def blocking1(): while True: yield 'first blocking function example' def blocking2(): while True: yield 'second blocking function example' for i in blocking1(): print 'this will be shown' for i in blocking2(): print 'this will not be shown' I have two functions which contain while True loops. These will yield data which I will then log somewhere (most likely, to an sqlite database). I've been playing around with threading and have gotten it working. However, I don't really like it... What I would like to do is make my blocking functions asynchronous. Something like: def blocking1(callback): while True: callback('first blocking function example') def blocking2(callback): while True: callback('second blocking function example') def log(data): print data blocking1(log) blocking2(log) How can I achieve this in Python? I've seen the standard library comes with asyncore and the big name in this game is Twisted but both of these seem to be used for socket IO. How can I async my non-socket related, blocking functions?

• Rename Files in Python

  - by Jeff

  Hi all, Im trying to rename some files in a directory using python. I've looked around the forums here, and because i'm a noob, I cant adapt what I need from what is out there. Say I have a file called CHEESE_CHEESE_TYPE.*** and want to remove "Cheese_" so my resulting filename would be "CHEESE_TYPE" Im trying to use the os.path.split but it's not working properly. I have also considered using string manipulations, but have not been successful with that either. Any help would be greatly appreciated. Thanks.

• How python logging get it's configuration

  - by Andrew_1510

  I used to Python logging, it works fine. The logging.basicConfig(...) set in one module (a some.py file), then we can use logging every where. Obviously, logging is global. The question is how logging find it's settings, when we not call the module where basicConfig(...) appeared (in some.py file )? Is logging scan all the packages? Even the logging.basicConfig(...) put into an any.py and the module (any.py) never get imported, or not used anywhere, the logging setting take effect!

• Python finding index in a array

  - by NIH

  I am trying to see if a company from a list of companies is in a line in a file. If it is I utilize the index of that company to increment a variable in another array. The following is my python code. I keep getting the following error: AttributeError: 'set' object has no attribute 'index'. I cannot figure out what is going wrong and think the error is the line that is surrounded by **. companies={'white house black market', 'macy','nordstrom','filene','walmart'} positives=[0 for x in xrange(len(companies))] negatives=[0 for x in xrange(len(companies))] for line in f: for company in companies: if company in line.lower(): words=tokenize.word_tokenize(line) bag=bag_of_words(words) classif=classifier.classify(bag) if classif=='pos': **indice =companies.index(company)** positives[indice]+=1 elif classif=='neg': **indice =companies.index(company)** negatives[indice]+=1

• Way to kill python thread from inside thread?

  - by user859434

  I have some python code that currently performs expensive computation by performing the computation in parallel through many threads. For a given time period, many threads are created and started on the fly that share the same code which is explicitly stated within the run method of the thread. My question is how do I stop/kill a thread at the end of its run method? (the run is only called once) I need to do this in order to create more threads for the next batch of computation. #Example class someThread(threading.Thread): def __init__(self): #some init code def run(self): #Explicitly Stated Code without constant loops #Something performed to stop/kill this thread

• Visual Studio 2010 Productivity Tips and Tricks&ndash;Part 1: Extensions

  - by ToStringTheory

  I don’t know about you, but when it comes to development, I prefer my environment to be as free of clutter as possible.  It may surprise you to know that I have tried ReSharper, and did not like it, for the reason that I stated above.  In my opinion, it had too much clutter.  Don’t get me wrong, there were a couple of features that I did like about it (inversion of if blocks, code feedback), but for the most part, I actually felt that it was slowing me down. Introduction Another large factor besides intrusiveness/speed in my choice to dislike ReSharper would probably be that I have become comfortable with my current setup and extensions.  I believe I have a good collection, and am quite happy with what I can accomplish in a short amount of time.  I figured that I would share some of my tips/findings regarding Visual Studio productivity here, and see what you had to say. The first section of things that I would like to cover, are Visual Studio Extensions.  In case you have been living under a rock for the past several years, Extensions are available under the Tools menu in Visual Studio: The extension manager enables integrated access to the Microsoft Visual Studio Gallery online with access to a few thousand different extensions.  I have tried many extensions, but for reasons of lack reliability, usability, or features, have uninstalled almost all of them.  However, I have come across several that I find I can not do without anymore: NuGet Package Manager (Microsoft) Perspectives (Adam Driscoll) Productivity Power Tools (Microsoft) Web Essentials (Mads Kristensen) Extensions NuGet Package Manager To be honest, I debated on whether or not to put this in here.  Most people seem to have it, however, there was a time when I didn’t, and was always confused when blogs/posts would say to right click and “Add Package Reference…” which with one of the latest updates is now “Manage NuGet Packages”.  So, if you haven’t downloaded the NuGet Package Manager yet, or don’t know what it is, I would highly suggest downloading it now! Features Simply put, the NuGet Package Manager gives you a GUI and command line to access different libraries that have been uploaded to NuGet. Some of its features include: Ability to search NuGet for packages via the GUI, with information in the detail bar on the right. Quick access to see what packages are in a solution, and what packages have updates available, with easy 1-click updating. If you download a package that requires references to work on other NuGet packages, they will be downloaded and referenced automatically. Productivity Tip If you use any type of source control in Visual Studio as well as using NuGet packages, be sure to right-click on the solution and click "Enable NuGet Package Restore". What this does is add a NuGet package to the solution so that it will be checked in along side your solution, as well as automatically grab packages from NuGet on build if needed. This is an extremely simple system to use to manage your package references, instead of having to manually go into TFS and add the Packages folder. Perspectives I can't stand developing with just one monitor. Especially if it comes to debugging. The great thing about Visual Studio 2010, is that all of the panels and windows are floatable, and can dock to other screens. The only bad thing is, I don't use the same toolset with everything that I am doing. By this, I mean that I don't use all of the same windows for debugging a web application, as I do for coding a WPF application. Only thing is, Visual Studio doesn't save the screen positions for all of the undocked windows. So, I got curious one day and decided to check and see if there was an extension to help out. This is where I found Perspectives. Features Perspectives gives you the ability to configure window positions across any or your monitors, and then to save the positions in a profile. Perspectives offers a Panel to manage different presets/favorites, and a toolbar to add to the toolbars at the top of Visual Studio. Ability to 'Favorite' a profile to add it to the perspectives toolbar. Productivity Tip Take the time to setup profiles for each of your scenarios - debugging web/winforms/xaml, coding, maintenance, etc. Try to remember to use the profiles for a few days, and at the end of a week, you may find that your productivity was never better. Productivity Power Tools Ah, the Productivity Power Tools... Quite possibly one of my most used extensions, if not my most used. The tool pack gives you a variety of enhancements ranging from key shortcuts, interface tweaks, and completely new features to Visual Studio 2010. Features I don't want to bore you with all of the features here, so here are my favorite: Quick Find - Unobtrusive search box in upper-right corner of the code window. Great for searching in general, especially in a file. Solution Navigator - The 'Solution Explorer' on steroids. Easy to search for files, see defined members/properties/methods in files, and my favorite feature is the 'set as root' option. Updated 'Add Reference...' Dialog - This is probably my favorite enhancement period... The 'Add Reference...' dialog redone in a manner that resembles the Extension/Package managers. I especially love the ability to search through all of the references. "Ctrl - Click" for Definition - I am still getting used to this as I usually try to use my keyboard for everything, but I love the ability to hold Ctrl and turn property/methods/variables into hyperlinks, that you click on to see their definitions. Great for travelling down a rabbit hole in an application to research problems. While there are other commands/utilities, I find these to be the ones that I lean on the most for the usefulness. Web Essentials If you have do any type of web development in ASP .Net, ASP .Net MVC, even HTML, I highly suggest grabbing the Web Essentials right NOW! This extension alone is great for productivity in web development, and greatly decreases my development time on new features. Features Some of its best features include: CSS Previews - I say 'previews' because of the multiple kinds of previews in CSS that you get font-family, color, background/background-image previews. This is great for just tweaking UI slightly in different ways and seeing how they look in the CSS window at a glance. Live Preview - One word - awesome! This goes well with my multi-monitor setup. I put the site on one monitor in a Live Preview panel, and then as I make changes to CSS/cshtml/aspx/html, the preview window will update with each save/build automatically. For CSS, you can even turn on live-update, so as you are tweaking CSS, the style changes in real time. Great for tweaking colors or font-sizes. Outlining - Small, but I like to be able to collapse regions/declarations that are in the way of new work, or are just distracting. Commenting Shortcuts - I don't know why it wasn't included by default, but it is nice to have the key shortcuts for commenting working in the CSS editor as well. Productivity Tip When working on a site, hit CTRL-ALT-ENTER to launch the Live Preview window. Dock it to another monitor. When you make changes to the document/css, just save and glance at the other monitor. No need to alt tab, then alt tab before continuing editing. Conclusion These extensions are only the most useful and least intrusive - ones that I use every day. The great thing about Visual Studio 2010 is the extensibility options that it gives developers to utilize. Have an extension that you use that isn't intrusive, but isn't listed here? Please, feel free to comment. I love trying new things, and am always looking for new additions to my toolset of the most useful. Finally, please keep an eye out for Part 2 on key shortcuts in Visual Studio. Also, if you are visiting my site (http://tostringtheory.com || http://geekswithblogs.net/tostringtheory) from an actual browser and not a feed, please let me know what you think of the new styling!

• Does Ctypes Structures and POINTERS automatically free the memory when the Python object is deleted?

  - by jsbueno

  When using Python CTypes there are the Structures, that allow you to clone c-structures on the Python side, and the POINTERS objects that create a sofisticated Python Object from a memory address value and can be used to pass objects by reference back and forth C code. What I could not find on the documentation or elsewhere is what happens when a Python object containing a Structure class that was de-referenced from a returning pointer from C Code (that is - the C function alocated memory for the structure) is itself deleted. Is the memory for the original C structure freed? If not how to do it? Furthermore -- what if the Structure contains Pointers itself, to other data that was also allocated by the C function? Does the deletion of the Structure object frees the Pointers onits members? (I doubt so) Else - -how to do it? Trying to call the system "free" from Python for the Pointers in the Structure is crashing Python for me. In other words, I have this structure filled up by a c Function call: class PIX(ctypes.Structure): """Comments not generated """ _fields_ = [ ("w", ctypes.c_uint32), ("h", ctypes.c_uint32), ("d", ctypes.c_uint32), ("wpl", ctypes.c_uint32), ("refcount", ctypes.c_uint32), ("xres", ctypes.c_uint32), ("yres", ctypes.c_uint32), ("informat", ctypes.c_int32), ("text", ctypes.POINTER(ctypes.c_char)), ("colormap", ctypes.POINTER(PIXCOLORMAP)), ("data", ctypes.POINTER(ctypes.c_uint32)) ] And I want to free the memory it is using up from Python code.

• Installed mountain lion, getting a python virtual env error?

  I recently installed mountain lion (10.8) and when I open up my terminal I get this message: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named virtualenvwrapper.hook_loader virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly. Before I try and fix this, I was hoping someone could guide me as I haven't touched python in a while and I don't want to mess up this installation.

• When a python process is killed on OSX, why doesn't it kill the child processes?

  - by Hugh

  I found myself getting very confused a while back by some changes that I found when moving Python scripts from Linux over to OSX... On Linux, if a python script has called os.system(), and the calling process is killed, the called process will be killed at the same time. On OSX, however, if the main process is killed, anything that it launched is left behind. Is there something somewhere in OSX/Python where I can change this behaviour? This is causing problems on our render farm, where the processes can be killed from the management GUI, but the top level process is really just a wrapper, so, while the render farm management might think that the process has gone and the machine is freed up for another task, the actual processor-intensive task is still running, which can lead to huge blockages. I know that I could write more logic to catch the kill signal and pass it on to the child processes, but I was hoping that it might be something that could be enabled at a lower level.

• How to choose a web server for a Python application?

  - by Phil

  Information and prerequisites: I have a project which is, at its core, a basic CRUD application. It doesn't have long running background processes which it forks at the beginning and talks to later on, nor does it have long running queries or kept alive connection requirements. It receives a request, makes some queries to the database and then responds. In order to serve static files and cachable files fast, I am going to use Varnish in all cases. Here is my question: After reading about various Python web application servers, I have seen that they all have their "fans" for certain, usually "personal" reasons, which got me confused since each usecase differs from the next. How can I learn about the core differentiating factors of Python web servers (in order) to decide how suitable they are for my project and if one would be better than the other? What are your (technically provable) thoughts on the matter? How should I choose a Python web server? Thank you.
