In your calls to the `*print*` function, you are not calling the `*mean*` and `*mean2*` functions that you declared to calculate averages. So Python sees you trying to concatenate two function objects to strings and is not happy. That's one thing.
Secondly, your code could be refactored to define one `*mean*` function as your functions do virtually the same thing. Then, you could just call it as needed. Thirdly, you could use the `*with*` keyword. See "7.2.
