Question

In the game of Lucky Sevens, the player rolls a pair of dice. If the dots add up to 7, the player wins $4; otherwise, the player loses $1. Suppose that, to entice the gullible, a casino tells players that there are many ways to win: (1, 6), (2, 5), and soon. A little mathematical analysis reveals that there are not enough ways to win to make the game worthwhile; however, because many people's eyes glaze over at the first mention of mathematics “wins $4”.

      Your challenge is to write a program in python that demonstrates the futility of playing the game. Your Python program should take as input the amount of money that the player wants to put into the pot, and play the game until the pot is empty.

          The program should have at least TWO functions (Input validation and Sum of the dots of user’s two dice). Like the program 1, your code should be user-friendly and able to handle all possible user input. The game should be able to allow a user to ply several times.

          The program should print a table as following:

      Number of rolls             Win or Loss                Current value of the pot

                  1                                 Put                                    $10

                  2                                 Win                                  $14

                  3                                 Loss                                  $11

                  4

                  ##                              Loss                                  $0

        You lost your money after ## rolls of play.

        The maximum amount of money in the pot during the playing is $##.

        Do you want to play again?

      At that point the player’s pot is empty (the Current value of the pot is zero), the program should display the number of rolls it took to break the player, as well as maximum amount of money in the pot during the playing.

Answer 1

import random

# function to roll 2 die and return the result of sum of those die

def rollDie():

return(random.randint(1,6) + random.randint(1,6))

def main():

while True: # loop that continues till the user wants

pot = int(raw_input('Enter the money in the pot : $')) # input of initial pot

rolls = 0

maxPot = pot

print('%20s %20s %s'%('Number of rolls','Win or Loss','Current value of the pot'))

# loop that continues till the pot is non-empty

while pot > 0:

rolls = rolls + 1

result = rollDie()

# check the result

if result == 7:

pot = pot + 4

print('%20d %20s %10s' %(rolls,'Win','$'+str(pot)))

else:

pot = pot - 1

print('%20d %20s %10s' %(rolls,'Loss','$'+str(pot)))

if pot > maxPot: #check for maxPot

maxPot = pot

#print the result

print('Took %d rolls to empty the pot' %(rolls))

print('Maximum pot : $%d' %(maxPot))

cont = raw_input('Do you want to continue ? (y/n) ')

if cont.lower() == 'n':

break

#call the main function

if _name_ == "__main__":

main()
