Write a Python program that allows a user to play Rock

-

Paper

-

Scissors

-

Lizard

-

Spock against the

computer. Have the program keep score of how many times each has won a round.

Write

functions

to

do the follow

ing:

1.

Displays the menu options to play the game, to display the score, or to quit.

Checks user input for validity and then returns the inputted value.

2.

Asks the user to input their choice: rock, paper, scissors, lizard, or Spock.

Checks user input for va

lidity and then returns the inputted value.

3.

Randomly

chooses

the computer’s throw and returns the value.

4.

Compares the two throws and returns who is the winner of that round.

Rock

crushes

scissors, and

lizard. Paper

covers

rock and

disproves

Spock. Scissors

cuts

paper and

decapitates lizard. Lizard

poisons Spock and eats paper.

Spock vaporizes rock, and

smashes scissors.

5.

Displays the scores.

The program repeats until the user decides to quit. Display

the final score before exiting.

Do not use global variables.

Check all user input for invalid values.

Solution

# The Python program for the above questions are:

# \"rock\", \"paper\", \"scissors\", \"lizard\", \"Spock\" to numbers

# 0 - rock, 1 - Spock, 2 - paper, 3 - lizard, 4 - scissors

import random

def number_to_name(number):

# convert number to a name

if number == 0:

return \"rock\"

elif number == 1:

return \"Spock\"

elif number == 2:

return \"paper\"

elif number == 3:

return \"lizard\"

else:

return \"scissors\"

  

def name_to_number(name):

# convert name to number

if name == \"rock\":

return 0

elif name == \"Spock\":

return 1

elif name == \"paper\":

return 2

elif name == \"lizard\":

return 3

else:

return 4

  

def rpsls(name):

# convert name to player_number using name_to_number

player_number = name_to_number(name)

# compute random guess for comp_number using random.randrange()

comp_number = random.randrange(0,5)

  

# compute difference of player_number and comp_number modulo five

difference = (player_number - comp_number) % 5

# convert comp_number to name using number_to_name

comp_name = number_to_name(comp_number)

# print results

print \"Player chooses\", name

print \"Computer chooses\", comp_name

if difference == 1 or difference == 2:

print \"Player wins!\"

elif difference == 3 or difference == 4:

print \"Computer wins!\"

else:

print \"Player and Computer tie!\"

print \"Thanks for Playing this Game\"
