Hi,
I was wondering if anyone knew of a built in Python function that will
check if an item is a member of a list, i.e., if item i is a member of
list l.
I read of a function "in" but I can't seem to get that to work and
finding pages for "python in" does not reveal very many relevant
sources.

Yes, `in` is the relevant operator. It's quite simple to use: a = [1, 4, 9, 16, 25] 2 in a
False 4 in a
True
If you're having problems using it in some circumstance, you'll have to
be specific.

Thanks, I was using "in" incorrectly. Thanks a lot! This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
