Googling for "python is not java" may be a good start. Also, here are 2
common C-style smells:

1/ using explicit indexing instead of iteration:

C-smell :
for i in range(len(seq)):

for item in seq:

# or if you need the index too:
for i, item in enumerate(seq):
  do_something_with(i, item)

2/ functions that returns a status code and modify their arguments. The
pythonic way is to have the function return multiple args and raise an
exception if something went wrong

python -c "print '@'.join(['.'.join([w[::-1] for w in p.split('.')]) for
p in 'onurb at xiludom.gro'.split('@')])"
