Divide a path on the extension separator

Divide a path on the extension separator.

import os.path

for path in ['test.txt',
             'filename',
             '/user/system/test.txt',
             '/',
             '']: print('"%s" :' % path, os.path.splitext(path))

Output:

"test.txt" : ('test', '.txt')
"filename" : ('filename', '')
"/user/system/test.txt" : ('/user/system/test', '.txt')
"/" : ('/', '')
"" : ('', '')
