Should we always use tuples when instantiating them only once? E.g. *if*abc *in* ('e', 'f'): instead of *if* abc *in* ['e', 'f']:
They appear to be slightly faster sometimes.
Hi
For constant tuples ( once whose items are expressed by literals ) it is true.
Thanks Harsh

Performance-wise, I don't think it matters much; after all, most time is spent inside the loop, not in instantiating a list or tuple. Conceptually, a list often makes more sense (a list would be different items of the same type, while a tuple represents different properties of the same item).
