os.path.splitext(filename) splits a filename into a name part (which may include
a path) and an extension part:
import os
f, e = os.path.splitext(filename)
the extension will include the separator, so the following is always true:
assert f + e == filename
if you don't want the period, you can strip it off:
if e[:1] == ".":
e = e[1:]
but it's often easier to change your code to take the dot into account; instead
of
if e[:1] == ".":
e = e[1:]
if e == "txt":
handle_text_file(filename)
elif e in ("png", "jpg"):
handle_image_file(filename)
do
if e == ".txt":
handle_text_file(filename)
elif e in (".png", ".jpg"):
handle_image_file(filename)
on the other hand, for maximum portability, you can use
f, e = os.path.splitext(filename)
if e.startswith(os.extsep):
e = e[len(os.extsep):]
if e == "txt":
...
but that's probably overkill...
