"In computer science, polymorphism means allowing a single definition
to be used with different types of data (specifically, different
classes of objects)."

>>> len("abcd")
4
>>> len([1,2,3,4,5,6])
6

Looks pretty polymorphic to me. In fact, Python's polymorphism support
is so good that it makes inheritance much less important than it is in
other languages.
