Games of Chance – Using random numbers in Python

This is my solution to the Codecademy Pro Project “Games of Chance” using Python to generate and work with random numbers. The aim is to prduce a number of functions simulating popular games of chance, and taking in parameters to represent a “bet” and in some cases a “call”. Includes the “extra challenge” solutions.

import random

money = 100

#Write your game of chance functions here

#function to play a simple game of coin toss with player guessing Heads or Tails

def coin_toss(guess, bet):
  if bet > money:
    print('You don\'t have enough green to place that bet!')
    print('The maximum bet you can make is £' + str(money))
    return 0
  if (guess != 'Heads') and (guess != 'Tails'):
    print('Invalid guess. You can choose Heads or Tails.')
    return 0
  toss = random.randint(1, 2)
  if (guess == 'Heads') and (toss == 1):
    print('Lucky guess! The toss is Heads. You win!')
    return bet
  elif (guess == 'Tails') and (toss == 2):
    print('Lucky guess! The toss is Tails. You win!')
    return bet
  else:
    if toss == 1:
      print('The toss was Heads. You lose.')
    if toss == 2:
      print('The toss was Tails. You lose.')
    return -bet
