Sort filenames in directory in ascending order [duplicate]

by

Assuming there’s just one number in each file name:

>>> dirFiles = ['Picture 03.jpg', '02.jpg', '1.jpg']
>>> dirFiles.sort(key=lambda f: int(filter(str.isdigit, f)))
>>> dirFiles
['1.jpg', '02.jpg', 'Picture 03.jpg']

A version that also works in Python 3:

>>> dirFiles.sort(key=lambda f: int(re.sub('\D', '', f)))
