slice behavior is not consistent for negative lower or upper arguments, which could be surprising: >>> 'hello'[:-2] 'hel' >>> 'hello'[:-1] 'hell' >>> 'hello'[:-0] '' this is obvious when written as literal, but not so obvious when using variables in expressions like 'fullname[:-len(lastname)]'. same goes for 'lower'.
