Get Filename Without Extension in Python

Question

If I have a filename like one of these:

1.1.1.1.1.jpg

1.1.jpg

1.jpg

How could I get only the filename, without the extension? Would a regex be appropriate?

>>> import os
>>> os.path.splitext("1.1.1.1.1.jpg")
('1.1.1.1.1', '.jpg')

In most cases, you shouldn't use a regex for that.

os.path.splitext(filename)[0]

This will also handle a filename like .bashrc correctly by keeping the whole name.
