Replacing Filename characters with python

Question

I have some code which adds the word \"_manual\" onto the end of a load of filenames.. I need to change the script so that it deletes the last two letters of the filename (ES)

Answer 1

For a more generalized take on hughdbrown's answer. This code can be used to remove any particular character or set of characters.

import os

paths = (os.path.join(root, filename)
        for root, _, filenames in os.walk('C:\FolderName')
        for filename in filenames)

for path in paths:
    # the '#' in the example below will be replaced by the '-' in the filenames in the directory
    newname = path.replace('#', '-')
    if newname != path:
        os.rename(path, newname)
