This suggests that you have a variable somewhere called input
that is hiding the function. Try doing del(input)
and try it again.

As to what input does; it evaluates whatever string you give
to it so if your user types in some malicious Python code
input will execute it. For that reason input is usually frowned
on as a security risk and int(raw_input()) is preferred.
