Call a function from another file?

Question

Set_up: I have a .py file for each function I need to use in a program.

In this program, I need to call the function from the external files.

I\'ve tried:

Answer 1

Inside MathMethod.Py.

def Add(a,b):
   return a+b 

def subtract(a,b):
  return a-b

Inside Main.Py

import MathMethod as MM 
  print(MM.Add(200,1000))

Output:1200
