This doesn't do what you think it does. The parameter to rstrip is a set:
as long as the last character is in the set 'abcdhiloprs/', it will remove
it and check the next one. All of the characters in "shop" are in that
In a few minutes, I couldn't think of a clever one-liner to do this. You
could do it with re.sub, but that seems like overkill.
chk = '/src/oship/atbldr'
cwd = os.getcwd()
if cwd.endswith( chk ):
cwd = cwd[:-len(chk)]
