Can anyone help me find the problem in my code

Question

When I return a variabele in the base case of my recursive function, it does not receive the value and receives None instead. Here is the code.

Hi. You forgot to return 'count' at the end of 'calculatePaths'. If you add that, it works. You don't return anything, therefore "None" is what you get.
