What would be a good scheme for storing and referencing these files? I considered just making a folder "resources" in the main directory, but there is a problem; Some images are used from w...

Is there a way to programmatically force a Python script to drop into a REPL at an arbitrary point in its execution, even if the script was launched from the command line?

I have no problems getting the file to upload and if I save it to disk, all formatting is intact. I wrote a function to read in the the file within Django using: data = csv.reader(f.read()) where f is the Django file object that I get from 'form.cleaned_data['file']' and yes the file is already bound to the form. When I try to read ...

I was optimising some Python code, and tried the following experiment: import time start = time.clock() x = 0 for i in range(10000000): x += 1 end = time.clock() print '+=',end-start start = time.clock() x = 0 for i in range(10000000): x -= -1 end = time.clock() print '-=',end-start The second loop is reliably faster, anyw...
I have some code that is using mechanize and a password protected site. I can login just fine and get the results I expect.
