Eh? How is the first easier to read than the second?? You have a nested function call in the first! Regardless, testing if a member is part of a ranged set is always going to be slower. It's the nature of what you're doing. Building a set and then searching it takes much longer than a single modulus and subtraction (which is all an integer comparison is). -- http://mail.python.org/mailman/listinfo/python-list
