What I'd imagine would be stripping of a suffix or the first match in a
list of suffixes exactly once.

TO me this seems the most common use case, though one is surprised how
functions can be used.


Example:

def strip_suffix(str,*suffixes):
    for suffix in suffixes:
        if str.endswith(suffix):
            return str[-len(suffix):]
    return str
