You shouldn't use the module string anymore, instead use string-methods.

Because then you need to know how large that string is. That makes the
case-distinction much easier - as -1 can never be the position of a
substring.
Besides, a value of len(haystack) + 1 says "The needle is beyond that
string" - which is bogus.

>>> "".find("fooob")
-1
as expected. Which python version do you use?
