If you replace None to another value that cannot be compared with int (e.g. string), you will got the same nasty case.Here's a particularly nasty case:l = [(1, None), (2, None)] l.sort() l[(1, None), (2, None)]l = [(1, None), (2, None), (3, 4)] l.sort() l[(1, None), (2, None), (3, 4)]l = [(1, None), (2, None), (3, 4), (2, 3)] l.sort()Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unorderable types: int() < NoneType()
