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(x):
    '''square x'''
    return x**2

def sum_of_squares(x, y):
    '''sum of squares of x and y'''
    return square(x) + square(y)

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