how much memory do you have?

why not try it out?  It's not exactly difficult to create large
tuples:

    T = tuple(xrange(100001))

"in" does a linear search.  The more data you have, the longer
time it takes (on average).

on an old 200 mhz box, I can do about ten "100000 in T"
searches per second.  Using a dictionary of the same size,
I can do about 200,000 lookups per second.

ymmv, as usual.
