Question 3

Given below is semi-complete code of a module basic.py :

#
"""..............."""  
def square(x):
"""..............."""
    return mul(x, x)
...............mul(x, y):
"""..............."""
    return x * y
def div(x, y):
    """..............."""
    return float(x)/y
...............fdiv(x, y)...............
"""..............."""
...............x//y
def floordiv(x, y)...............
...............fdiv(x, y)

Complete the code. Save it as a module.

Answer 
# basic.py
"""This module contains basic mathematical operations."""

def square(x):
    """Returns the square of a number."""
    return mul(x, x)

def mul(x, y):
    """Returns the product of two numbers."""
    return x * y

def div(x, y):
    """Returns the result of dividing x by y."""
    return float(x) / y

def fdiv(x, y):
    """Returns the result of floor division of x by y."""
    return x // y

def floordiv(x, y):
    return fdiv(x, y)

The code is saved with .py extension to save it as module.
