[Python-Dev] UserString (original) (raw)

I noticed that UserString objects have methods that do not accept other UserString objects as arguments:

from UserString import UserString UserString('slartibartfast').count(UserString('a'))

Traceback (most recent call last): File "<pyshell#2>", line 1, in -toplevel- UserString('slartibartfast').count(UserString('a')) File "C:\PY24\lib\UserString.py", line 66, in count return self.data.count(sub, start, end) TypeError: expected a character buffer object

UserString('abc') in UserString('abcde')

Traceback (most recent call last): File "<pyshell#1>", line 1, in -toplevel- UserString('abc') in UserString('abcde') File "C:\PY24\lib\UserString.py", line 35, in contains return char in self.data TypeError: 'in ' requires string as left operand

This sort of thing is easy to test for and easy to fix. The question is whether we care about updating this module anymore or is it a relic. Also, is the use case one that we care about. AFAICT, this has never come up before.
