strip() function doesn't remove trailing numbers

Question

I try the following code but fails to remove the trailing digits using python 3.4.3

file_name = "48athens22.jpg"
result = file_name.strip("0123456789")
print (result)

Output: athens22.jpg

What has gone wrong?

Answer 1

strip() only strips from the end of a string; the 22 is not at the end of the string.

Here's how to do what you want:

import os


def strip_filename(filename):
    root, ext = os.path.splitext(filename)
    root = root.strip('0123456789')
    return root + ext


print(strip_filename('48athens22.jpg'))  # athens.jpg
