for example, i've noticed several java developers i know
write python code like
this:
foo_list = [...]
for i in range(len(foo_list)):
print '%d %s' % (i, foo_list[i])

Try googling for "python is not java" !-)

really? I'd say breaking stuff just because you can is remarkably
unpythonic.

which is a perfectly valid way of doing things if you're targeting older
Python platforms as we
know write python code like
this:
foo_list = [...]
for i in range(len(foo_list)):
print '%d %s' % (i, foo_list[i])
of course, one way to do this would be to use enumerate:
for i, foo in enumerate(foo_list):
print '%d %s' % (i, foo)
i'm guessing there is a lot
