Typeerror: 'nonetype' Object Has No Attribute '__getitem__'

I'm having an issue and I have no idea why this is happening and how to fix it. I'm working on developing a Videogame with python and pygame and I'm getting this error: File '/ho

Solution 1:

move.CompleteMove() does not return a value (perhaps it just prints something). Any method that does not return a value returns None, and you have assigned None to self.values.

Here is an example of this:

>>>defhello(x):...print x*2...>>>hello('world')
worldworld
>>>y = hello('world')
worldworld
>>>y>>>

You'll note y doesn't print anything, because its None (the only value that doesn't print anything on the interactive prompt).

Solution 2:

The function move.CompleteMove(events) that you use within your class probably doesn't contain a return statement. So nothing is returned to self.values (==> None). Use return in move.CompleteMove(events) to return whatever you want to store in self.values and it should work. Hope this helps.
