Question

In python:

The randrange(min, max) produces a random integer

greater than or equal to min and less than max.

So randrange(0,3) produces either 0, 1, or 2

Write a program that asks the user to input

paper, rock, scissors, or done

If they input something else, repeat  the question.

If they input 'done', exit the game loop.

If they input rock, paper, or scissors, have the

computer pick a random choice.

Write a function that takes two strings, each 'rock', 'paper', or 'scissors' and returns a value indicating whether the first string won, lost, or tied the contest.

(perhaps 1 for winning, 0 for a tie, -1 for a loss)

rules:

Rock smashes scissors. Scissors cut paper. Paper covers rock. If both players select the same choice, the round is a tie.

Use your function to determine the winner after each choice.

Keep track of how many times the player has won, lost, and tied.

Print whether the player or the computer won the round or if it is a tie.

When the game loop ends, print the number of wins, losses, and ties.
