It could even be introduced without breaking compatibility.

if being defined as
str.rstrip([iterable])
so you could either call
string.rstrip( [ '-dir' ] )
or  as
string.rstrip( '-dir' )


However I wouldn't be sure, that it really reduces the amount of
questions being asked.

In order to reduce the ambiguities one had to have two distinct functions.
If one wouldn't want to break backwards-compatibility, then the new
names would be  for stripping off prefixes / suffixes and could be
str.strip_prefix(prefixes) / str.rstrip_suffix(suffixes)


I'd love to have this functionality, though I can live with importing my
self written function.
