tem = sys.argv[1]
pos = tem.rfind('.')
if pos != -1:
  im,func = tem[:pos], tem[pos+1:]

Definitely.  Factoring out the .attr[sub] is even more readable to me.

Alternative (initially leaves func with leading '.'):
import os
im, func = os.path.splitext(sys.argv[1])
func = func[1:]

Example:
>>> s = os.path.splitext
>>> s('abc')
('abc', '')
>>> s('ab.c')
('ab', '.c')
>>> s('a.b.c')
('a.b', '.c')
