I hope I can get a better answer here:
Why isn't __sub__ defined for the internal strings? I want a good reason
for that, and not the "Go C++ if you want to do shit like that" that I
got on #python.
I mean, it wasn't much code:
import UserString
class mystr(UserString.UserString):
def __init__(self, data=""):
self.data = data
def __sub__(self, other):
return self.data.replace(other, "")
>>> s = mystr("foo bar foo foo foo bar")
>>> s - "foo"
' bar bar'
