Either I'm misunderstanding what you mean or you need to get a clue
about what Python can already do before you go around making suggestions
for what Python needs. Lists have supported "in" tests since at least
version 1.5.2:

Python 1.5.2 (#1, Nov  6 1999, 14:53:40) [C] on sco_sv3
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> if 3 in [1,2,3]: print "Yup, got it!"
... 
Yup, got it!

This feature may be older than version 1.5.2, but this is the oldest
version that I still have running anywhere.
