‘NoneType’ object has no attribute whatever

• none
• attribute
• object

Typically, you would get this from

something = get_answer()

# ... lots of code

if something.whatever() is 'cabbage':
    ...

You expected something to be an object returned by get_answer(), but for some reason, this function returned None (perhaps because you fell off the end of the function without an explicit return statement).

Obviously, the None object cannot perform the function you are asking it to perform, because it basically has no methods at all.

It’s hard to give general guidance, but some common fixes include explicitly checking that the result is not None, and using a try: block which guards against terminating on this error.
