That was good advice, but isn't going to help here. Because "input"
isn't a keyword, it's a builtin. If you want to check builtins as
well as keywords, you need
>>> if myInput in keyword.kwlist + dir(__builtins__):
(Although obviously you'd pre-build that list.)

?
>>> def check():
...     input = raw_input('Enter identifier to check >> ')
...     if input in keyword.kwlist:
...             print input, "is keyword"
...     else:
...             print input, "is not keyword"
...
Enter identifier to check >> input
input is not keyword
>>> check()
Enter identifier to check >> else
else is keyword
>>>
