You are supposed to use the in operator:
index = 0
while 1:
if not "something" in text[index:]:
break
IMHO, removing find() is good because index() does the same job
without violating the Samurai Principle
(http://c2.com/cgi/wiki?SamuraiPrinciple). It would be interesting to
see the patch that replaced find() with index(), did it really make
the code more cumbersome?
