An elegant solution to a trivial exercise

import math

# Define the Square function
def square(n):
    return n * n

# Define the Cube function
def cube(n):
    return n ** 3

# Define the square root function
def root(n):
    return math.sqrt(n)

# Defined a "main" function that ties everything up in a neat package
def main():
    m = int(input("Enter your number: "))
    print("The square of {0!s} is {1!s}".format(m, square(m))) # I used the String.format method to concatenate strings.
    print("The cube of {0!s} is {1!s}".format(m, cube(m))) # I also used the "!s" directive to force conversion to string implicitly.
    print("The square root of {0!s} is {1!s}".format(m, root(m)))
