Couple of things...

* isnumeric() is a function not a property so you have to call it
* == comparison to True/False does work but isn't pythonic, you can
just use logical operators
* as Colin has said, you are only checking if BOTH numbers are not
numeric, I suppose you need either or.

This should work:

NumberOne = input("Number 1: ")
NumberTwo = input("Number 2: ")
if not (NumberOne.isnumeric() and NumberTwo.isnumeric()):
    print("Those weren't numbers")

Thanks,
