Guess the Number Repeat

[eschneider92 at comcast.net]

How do I make the following program play the 'guess the number game' twice?

import random
guessesTaken = 0
print('Hello! What is your name?')
myName = input()
number = random.randint(1, 20)
print('Well, ' + myName + ', I am thinking of a number between 1 and 20.')
while guessesTaken < 6:
    print('Take a guess.') 
    guess = input()
    guess = int(guess)
    print('You have ' + str(5 - guessesTaken) + ' guesses left.')
    guessesTaken = guessesTaken + 1
    if guess < number:
        print('Your guess is too low.')
    if guess > number:
        print('Your guess is too high.')
    if guess == number:
        break
if guess == number:
    guessesTaken = str(guessesTaken)
    print('Good job, ' + myName + '! You guessed my number in ' + guessesTaken + ' guesses!')
if guess != number:
    number = str(number)
    print('Nope. The number I was thinking of was ' + number)
