• Create a file named mymath.py containing:
• A function add(a, b) → returns the sum of two numbers.
• A function sub(a, b) → returns the difference of two numbers.

In another file calculator.py:

It should ask the user to choose an operation (add or sub) and enter two numbers, then print the result.

Choose operation (add/sub): add
