  • Python namespace in between builtins and global?

    - by Paul
    Hello, As I understand it python has the following outermost namespaces: Builtin - This namespace is global across the entire interpreter and all scripts running within an interpreter instance. Globals - This namespace is global across a module, ie across a single file. I am looking for a namespace in between these two, where I can share a few variables declared within the main script to modules called by it. For example, script.py: import Log from Log import foo from foo log = Log() foo() foo.py: def foo(): log.Log('test') # I want this to refer to the callers log object I want to be able to call script.py multiple times and in each case, expose the module level log object to the foo method. Any ideas if this is possible? It won't be too painful to pass down the log object, but I am working with a large chunk of code that has been ported from Javascript. I also understand that this places constraints on the caller of foo to expose its log object. Thanks, Paul

  • Manipulating binary data in Python

    - by Dominic Bou-Samra
    I am opening up a binary file like so: file = open("test/test.x", 'rb') and reading in lines to a list. Each line looks a little like: '\xbe\x00\xc8d\xf8d\x08\xe4.\x07~\x03\x9e\x07\xbe\x03\xde\x07\xfe\n' I am having a hard time manipulating this data. If I try and print each line, python freezes, and emits beeping noises (I think there's a binary beep code in there somewhere). How do I go about using this data safely? How can I convert each hex number to decimal?

  • Python: Elegant way to check if at least one regex in list matches a string

    - by houbysoft
    Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

  • Python 3 - Module: subprocess

    - by Rhys
    Hi Stack Overflow users, I've encountered a frustrating problem, can't find the answer to it. Yesterday I was trying to find a way to HIDE a subprocess.Popen. So for example, if i was opening the cmd. I would like it to be hidden, permanently. I found this code: kwargs = {} if subprocess.mswindows: su = subprocess.STARTUPINFO() su.dwFlags |= subprocess.STARTF_USESHOWWINDOW su.wShowWindow = subprocess.SW_HIDE kwargs['startupinfo'] = su subprocess.Popen("cmd.exe", **kwargs) It worked like a charm! But today, for reasons I don't need to get into, I had to reinstall python 3 (32bit) Now, when I run my program I get this error: Traceback (most recent call last): File "C:\Python31\hello.py", line 7, in <module> su.dwFlags |= subprocess.STARTF_USESHOWWINDOW AttributeError: 'module' object has no attribute 'STARTF_USESHOWWINDOW' I'm using 32bit, python3.1.3 ... just like before. If you have any clues/alternatives PLEASE post, thanks. NOTE: I am looking for a SHORT method to hide the app, not like two pages of code please

  • Unable to access LinkedIn conections using python rauth library

    - by srinath sastry
    I was trying out this example at https://github.com/litl/rauth/blob/master/examples/linkedin-web.py I get a 403, Access to connections denied error and it returns KeyError: '_total'. r_network option is present. Has anyone faced this issue? Also if you look at http://docs.python-requests.org/en/latest/user/quickstart/#oauth-authentication, the 'requests' library is initializing resource_owner_key, resource_owner_secret apart from the application keys. Not sure how these are getting passed from the 'rauth' library, Was wondering if that was causing this 403 error.

  • python - checking if a user has admin privileges

    - by Matt
    Hi, I'm writing a little program as a self-learning project in Python 3.x. my idea is for the program to allow two fields of text entry to the user, and then plug the user's input into the value of two specific registry keys. What I was wondering, and something my books don't seem to cover, is if there is a simple way to make it check if the current user can access the registry. I'd rather it cleanly tell the user that he needs admin privileges than for the program to go nuts and crash because it's trying to access a restricted area. I'd like it to make this check as soon as the program launches, before the user is given any input options. What code is needed for this? thanks for the help

  • Building a minimal plugin architecture in Python.

    - by dF
    I have an application, written in Python, which is used by a fairly technical audience (scientists). I'm looking for a good way to make the application extensible by the users, i.e. a scripting/plugin architecture. I am looking for something extremely lightweight. Most scripts, or plugins, are not going to be developed and distributed by a third-party and installed, but are going to be something whipped up by a user in a few minutes to automate a repeating task, add support for a file format, etc. So plugins should have the absolute minimum boilerplate code, and require no 'installation' other than copying to a folder (so something like setuptools entry points, or the Zope plugin architecture seems like too much.) Are there any systems like this already out there, or any projects that implement a similar scheme that I should look at for ideas / inspiration?

  • Google Application Engine slow in case of Python...

    - by Aftershock
    hi, I am reading a "table" in Python in GAE that has 1000 rows and the program stops because the time limit is reached. (So it takes at least 20 seconds.)( Is that possible that GAE is that slow? Is there a way to fix that? Is this because I use free service and I do not pay for it? Thank you. The code itself is this: for u in userall: # userall has 1000 users for stockname in stocknamesall: # 4 stocks astock= stocksowned() astock.quantity = random.randint(1,100) astock.nameid = u.key() astock.stockid = stockname.key() liststocks.append(astock);

  • Python's urllib2 don't work on some sites

    - by Binny V A
    I found that you can't read from some sites using Python's urllib2(or urllib). An example... urllib2.urlopen("http://www.dafont.com/").read() # Returns '' These sites works when you visit the site. I can even scrap them using PHP(didn't try other languages). I have seen other sites with the same issue - but can't remember the URL at the moment. My questions are... What is the cause of this issue? Any workaround for this issue?

  • Why is this logical expression in python False?

  • Python proper use of __str__ and __repr__

    - by Peter
    Hey, My current project requires extensive use of bit fields. I found a simple, functional recipe for bit a field class but it was lacking a few features I needed, so I decided to extend it. I've just got to implementing __str__ and __repr__ and I want to make sure I'm following convention. __str__ is supposed to be informal and concice, so I've made it return the bit field's decimal value (i.e. str(bit field 11) would be "3". __repr__ is supposed to be a official representation of the object, so I've made it return the actual bit string (i.e. repr(bit field 11) would be "11"). In your opinion would this implementation meet the conventions for str and repr? Additionally, I have used the bin() function to get the bit string of the value stored in the class. This isn't compatible with Python < 2.6, is there an alternative method? Cheers, Pete

  • "Streaming" MJPG using python.

    - by tyler
    I have a webcam that I want to do some image processing on using Python. It's coming through as a Motion-JPEG. I want to try to process the stuff "live," but really what I want to do is this: Open the URL, start data streaming to some buffer... Read x bytes (where x is image size) to an image Process that image Display in result panel Return to number 2 The problem is that, while I do have the resolution, I have no idea how many bytes to read. I've tried googling the M-JPEG specification but can't find anything on if the images are separated by some header or what. Anybody have any ideas?

  • python class attribute

    - by chnet
    Hi, i have a question about class attribute in python. class base : def __init__ (self): pass derived_val = 1 t1 = base() t2 = base () t2.derived_val +=1 t2.__class__.derived_val +=2 print t2.derived_val # its value is 2 print t2.__class__.derived_val # its value is 3 The results are different. I also use id() function to find t2.derived_val and t2.class.derived_val have different memory address. My problem is derived_val is class attribute. Why it is different in above example? Is it because the instance of class copy its own derived_val beside the class attribute?

  • Python 2.6, 3 abstract base class misunderstanding

    - by Aaron
    I'm not seeing what I expect when I use ABCMeta and abstractmethod. This works fine in python3: from abc import ABCMeta, abstractmethod class Super(metaclass=ABCMeta): @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... And in 2.6: class Super(): __metaclass__ = ABCMeta @abstractmethod def method(self): pass a = Super() TypeError: Can't instantiate abstract class Super ... They both also work fine (I get the expected exception) if I derive Super from object, in addition to ABCMeta. They both "fail" (no exception raised) if I derive Super from list. I want an abstract base class to be a list but abstract, and concrete in sub classes. Am I doing it wrong, or should I not want this in python?

  • Python module seeing a full list as empty in another module

    - by Nick
    I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

  • Python faster way to read fixed length fields form a file into dictionary

    - by Martlark
    I have a file of names and addresses as follows (example line) OSCAR ,CANNONS ,8 ,STIEGLITZ CIRCUIT And I want to read it into a dictionary of name and value. Here self.field_list is a list of the name, length and start point of the fixed fields in the file. What ways are there to speed up this method? (python 2.6) def line_to_dictionary(self, file_line,rec_num): file_line = file_line.lower() # Make it all lowercase return_rec = {} # Return record as a dictionary for (field_start, field_length, field_name) in self.field_list: field_data = file_line[field_start:field_start+field_length] if (self.strip_fields == True): # Strip off white spaces first field_data = field_data.strip() if (field_data != ''): # Only add non-empty fields to dictionary return_rec[field_name] = field_data # Set hidden fields # return_rec['_rec_num_'] = rec_num return_rec['_dataset_name_'] = self.name return return_rec

  • Comment out a python code block

    - by gbarry
    Is there any mechanism to comment out large blocks of Python code? Right now the only ways I can see of commenting out code are to either start every line with a #, or to enclose the code in """ (triple quotes), except that actually makes it show up in various doc tools. Edit--After reading the answers (and referring to the "duplicate"), I have concluded the correct answer is "No". One person said so, and the rest lectured us about editors. Not a bad thing, but I feel it's important to put the answer at the top.

  • Sqlite and Python -- return a dictionary using fetchone()?

    - by AndrewO
    I'm using sqlite3 in python 2.5. I've created a table that looks like this: create table votes ( bill text, senator_id text, vote text) I'm accessing it with something like this: v_cur.execute("select * from votes") row = v_cur.fetchone() bill = row[0] senator_id = row[1] vote = row[2] What I'd like to be able to do is have fetchone (or some other method) return a dictionary, rather than a list, so that I can refer to the field by name rather than position. For example: bill = row['bill'] senator_id = row['senator_id'] vote = row['vote'] I know you can do this with MySQL, but does anyone know how to do it with SQLite? Thanks!!!

  • Bash or python for changing spacing in files

    - by Werner
    Hi, I have a set of 10000 files. In all of them, the second line, looks like: AAA 3.429 3.84 so there is just one space (requirement) between AAA and the two other columns. The rest of lines on each file are completely different and correspond to 10 columns of numbers. Randomly, in around 20% of the files, and due to some errors, one gets BBB 3.429 3.84 so now there are two spaces between the first and second column. This is a big error so I need to fix it, changing from 2 to 1 space in the files where the error takes place. The first approach I thought of was to write a bash script that for each file reads the 3 values of the second line and then prints them with just one space, doing it for all the files. I wonder what do oyu think about this approach and if you could suggest something better, bashm python or someother approach. Thanks

  • How to Redirect a Python Console output to a QTextBox

    - by krishnanunni
    Hello, I'm working on developing a GUI for the recompilation of Linux kernel. For this I need to implement 4-5 Linux commands from Python. I use Qt as GUI designer. I have successfully implemented the commands using os.system() call. But the output is obtained at the console. The real problem is the output of command is a listing that takes almost 20-25 min continuous printing. How we can transfer this console output to a text box designed in Qt. Can any one help me to implement the setSource() operation in Qt using source as the live console outputs.

    I have a python CGI which runs some script in the background and shows the stdout in the html page. I run the script when the user clicks some button in the page. My problem is when the script starts running the page becomes busy and the user can't use the other client side features in the page. What I want is: The script should run in background when the user clicks the button and should notify the CGI when run is complete. Then the CGI show should the stdout of the script run. How can this be done?
