Create a game of Rock Paper Scissors using random import a w

Create a game of Rock, Paper, Scissors using random import, a while loop, and a series of if statements. The user should input either “rock”, “paper”, or “scissors”- and the output should print the computers choice, as well as the result of the match. If the match is tied, it should automatically start a new match. For example:

Example 1:

rock, paper, scissors?: rock

Computer chose scissors.

Rock smashes scissors, you win!

Example 2:

rock, paper, scissors?: paper

Computer chose scissors.

Scissors cut paper, you lose!

Example 3:

rock, paper, scissors?: scissors

Computer chose scissors.

rock, paper, scissors?: rock

Computer chose paper.

Paper covers rock, you lose!
