How to calculate a mod b in Python?

Question

Is there a modulo function in the Python math library?

Isn\'t 15 % 4, 3? But 15 mod 4 is 1, right?

Answer 1

I don't think you're fully grasping modulo. a % b and a mod b are just two different ways to express modulo. In this case, python uses %. No, 15 mod 4 is not 1, 15 % 4 == 15 mod 4 == 3.
