Courses Plus Student 937 PointsDealing with variables and integers.
I was following the video and playing around with variables. I set age equal to 20, multiplied it by 10 and divided it by 10, giving me a float of 20.0. That raised an interesting question, could I turn the variable back into an integer? I tried 'int("age")' but got back "ValueError: invalid literal for int() with base 10: 'age'". Purely for curiosity, how would you go about turning the variable back to an integer?

int(age)
You could also keep it from becoming a float to start with if you use integer division ("age //= 10") instead of regular division.
