Answer 1

In the first class total is a function as well as an attribute of the class. That is not okay :) Python thinks that the total you are referring to in the final line is the integer variable total and not the function.

It is considered a good practice to name the function total as get_total instead

Answer 2

This is because you have a property called total, as well as a function called total. When you run roll, you are overwriting the class's definition of total.

In other words, before you run roll, player1.total is a function. However, once you run roll, you set player1.total to be a number. From then on, when you reference player1.total, you are referring to that number.

You might want to rename the total function to something like getTotal, or something similar.
