Indentations matter a lot in python, and as the error suggests, you have an indentation problem. You should only indent when creating a new block of code, for example after if, for or while statements.

Just remove the whitespaces before module:

i = path.rfind('.')
module, attr = path[:i], path[i+1:]

print i
#or
import pdb; pdb.set_trace()
