Can someone explain to me the main difference between using def__mul__ and def__rmul__ when adding to class
Can someone explain to me the main difference between using def_mul_ and def_rmul_ when adding to class?

Good question! The
__mul__ method is needed if your class will be used in a numeric context on the left side of the multiplication operator. The
__rmul__ method is needed if your class will be used in a numeric context on the reflected side, that is the right side of the multiplication operator.
Post back if you need more help. Good luck!!
