Im trying to grab all data(text) coming from a URL which is constantly sending text, I tried using PHP but that would mean having the script running the whole time which it isn’t really made for (I think). So I ended up using a BASH script. At the moment I use wget (I couldn’t get CURL to output the text to a file) wget --tries=0 --ret...
I read somewhere that functions should always return only one type so the following code is considered as bad code: def x(foo): if 'bar' in foo: return (foo, 'bar') return None I guess the better solution would be def x(foo): if 'bar' in foo: return (foo, 'bar') return () Wouldn't it be cheaper memory wise to return a None ...
I'm writing a web app using python with web.py, and I want to implement my own logging system. I'd like to log detailed information about each request that come to python (static files are handled by web servers). Currently I'm thinking about writing the logs to a pipe. On the other side, there should be cronolog. My main concern is th...
I have a vector consisting of a point, speed and direction. We will call this vector R. And another vector that only consists of a point and a speed. No direction. We will call this one T. Now, what I am trying to do is to find the shortest intersection point of these two vectors. Since T has no direction, this is proving to be difficult...

I've always set up metaclasses something like this: class SomeMetaClass(type): def __new__(cls, name, bases, dict): #do stuff here But I just came across a metaclass that was defined like this: class SomeMetaClass(type): def __init__(self, name, bases, dict): #do stuff here Is there any reason to prefer one ...

I'm trying to write a heavily email-based application in the Python SDK of Google App Engine. I've noticed that Google allows you to receive email via its API, and that it easily gives you access to the standard fields like From, To, Body, etc. However, if I'm trying to verify that an email address came from who it said it came from (kin...
EDIT: This question is invalid. Turns out a transparent proxy was making an onward HTTP 1.0 request even though urllib/httplib was indeed making a HTTP 1.1 request originally. ORIGINAL QUESTION: By default urllib2.urlopen always makes a HTTP 1.0 request. Is there any way to get it to talk HTTP 1.1 ? ...
If I make two lists of functions: def makeFun(i): return lambda: i a = [makeFun(i) for i in range(10)] b = [lambda: i for i in range(10)] why the lists a and b are not equal? For example: >>> a[2]() 2 >>> b[2]() 9 ...

If that line is not empty it continues. However, I am getting this error: ValueError: invalid literal for int() with base 10: ''.` It is re...
When I use urllib2 to make a HTTP 1.1 connection via a squid proxy, squid makes a new ongoing connection in HTTP 1.0. How can I persuade Squid to talk 1.1 to the destination server? ...

I'm using the trick "python -c 'import myscript.py'" to perform a syntax check on a script which uses 'import gtk'. I get the following error when performing the syntax check, which implies that the gtk module is executing a check for the X display, even though all that's being done at this point is to import the module. Traceback (mos...
I have a script that acts as a wrapper for some unit tests written using the Python unittest module. In addition to cleaning up some files, creating an output stream and generating some code, it loads test cases into a suite using unittest.TestLoader().loadTestsFromTestCase() I am already using optparse to pull out several command-li...
I've never used python before. I've used php for about 5 years now. I plan to learn python, but I'm not sure what for yet. If I can think of a project that might be better to do in python, I'll use that to learn it. Edit: just to add this as an important note, I do mean strictly for linux, not multi-platform. Edit 2: I'm hoping for obje...
