Exercise 22.1

1. Write a function called square() that takes a number as an argument and returns the square of that number.

2. Write a function called sum_of_squares() that takes two numbers as arguments, calls square() for each of them separately and returns the sum of their squares.

def square(a):
    number = a**2
    
    return number

def sum_of_squares(a, b):
    sum = square(a) + square(b)
    
    return sum

z = sum_of_squares(3.0, 4.0)
print(z)
