So I've got this snippet of code. And it works (It says 1 is non-prime).: n = 1 s = 'prime' for i in range(2, n / 2 + 1): if n == 1 or n % i == 0: s= 'non-' +s break print s My problem is that if I change the fourth line to: if n % i == 0 or n == 1:, it doesn't work (it says 1 is prime.) Why is that? Since I'm us...

Here's one specific example; but I'm looking for a general answer if possible. #m is a MatchObject #I know there's only one named group in the regex #I want to retrieve the name and the value g, v = m.groupdict().popitem() #do something else with m...
Say I have something like the following: dest = "\n".join( [line for line in src.split("\n") if line[:1]!="#"] ) (i.e. strip any lines starting with # from the multi-line string src) src is very large, so I'm assuming .split() will create a large intermediate list. I can change the list comprehension to a generator expression, but i...

I've been playing around with a timing decorator for my pylons app to provide on the fly timing info for specific functions. I've done this by creating a decorator & simply attaching it to any function in the controller I want timed. It's been pointed out however that decorators could add a fair amount of overhead to the call, and that ...
I'm new to python, and starting to learn website development with pylons and sqlalchemy. I've read the document of sqlalchemy and pylons, but still have a lot of problems.

Hi all, how can I iterate and retrieve all fields of a django model? I know that foo.item._meta.get_all_field_names() brings me all field names. How can I access those fields (incl. their actual values) on a model instance? (Except the normal notation foo.fieldname). I need this in order to build a custom output for my model including...
Hi there. In my program I need to download 3-4 files simultaneously (from different servers which are quite slow). I'm aware of the solution involving python threads or qt threads, but I'm wondering: since it seems to be a quite common task, maybe there's a library which I feed with urls and simply receive the files? Thanks in advance! ...

I want to convert an integer (int or long) a big-endian byte string. The byte string has to be of variable length, so that only the minimum number of bytes are used (the total length length of the preceding data is known, so the variable length can be inferred). My current solution is import bitstring bitstring.BitString(hex=hex(456))...
