I asked previously how the nested functions work, but unfortunately I still don't quite get it. To understand it better, can someone please show some real-wold, practical usage examples of nested functions? Many thanks ...

I wasn't aware of this, but apparently the and and or keywords aren't operators. They don't appear in the list of python operators. Just out of sheer curiosity, why is this? And if they aren't operators, what exactly are they? ...
I have an array of threads. Each of them call the run method continuously. At the end of each run method I want them to pause and wait. How can I get the threads to execute one at a time, and then continue the loop when all are finished? I need them to ALWAYS execute in order (ie: 1, 2, 3, 4 - 1, 2, 3, 4...) I'm currently using threadi...
Hello, I am a newbie going through a byte of python (3.0). This is the first programming language I have ever used. I am stuck at the point where you make a simple program that creates a backup zip file (p.75). I'm running Windows 7 (64 bit) with python 3.1. Prior to this I installed GNUWin32 + sources, and added C:\Program Files(x86)\Gn...

I do not know windows well, so that may explain my dilemma ... I am trying to run bcdedit in Windows 2008R2 from Python 2.6. My Python routine to run a command looks like this: def run_program(cmd_str): """Run the specified command, returning its output as an array of lines""" dprint("run_program(%s): entering" % cmd_str) ...
Python's tarfile module ignores errors during extraction by default, unless errorlevel is set to either 1 or 2 (or debug to 1 if only error messages need to be printed). Try doing a mkdir /tmp/foo && sudo chown root /tmp/foo && chmod a-w /tmp/foo and using tarfile to extract a .tar.gz file over /tmp/foo -- you will see that your Python...
i think you can defined either '__init__' or '__new__' in a class,but why all defined in django.utils.datastructures.py. my code: class a(object): def __init__(self): print 'aaa' def __new__(self): print 'sss' a()#print 'sss' class b: def __init__(self): print 'aaa' def __new__(self): ...
What is the most efficient way to alternate taking values from different iterators in Python, so that, for example, alternate(xrange(1, 7, 2), xrange(2, 8, 2)) would yield 1, 2, 3, 4, 5, 6. I know one way to implement it would be: def alternate(*iters): while True: for i in iters: try: yield i.nex...
I'm making a trivia webapp that will feature both standalone questions, and 5+ question quizzes. I'm looking for suggestions for designing this model. Should a quiz and its questions be stored in separate tables/objects, with a key to tie them together, or am I better off creating the quiz as a standalone entity, with lists stored for ...
In Python (2.5), should I use urllib or urllib2? What's the difference? They seem to do the same thing. (Bonus points, if I'm using Google App Engine, does this change the answer?) ...

I currently have a Python app I am developing which will data carve a block device for jpeg files. Let's just say that it sometimes works and sometimes doesn't. I have created it so that I read the block device till I find a ffd8, then I keep the stream open and search via looping for the ffd9 closure. Though I always need to take int...
I am still struggling with understanding classes, I am not certain but I have an idea that this function I have created is probably a good candidate for a class. The function takes a list of dictionaries, identifies the keys and writes out a csv file. First Q, is this function a good candidate for a class (I write out a lot of csv fil...
