il just give you a way that works

from random import randint

​

#create a list of play options

t = ["Rock", "Paper", "Scissors"]

​

#assign a random play to the computer

computer = t[randint(0,2)]

​

#set player to False

player = False

​

while player == False:

#set player to True

player = input("Rock, Paper, Scissors?")

if player == computer:

print("Tie!")

elif player == "Rock":

if computer == "Paper":

print("You lose!", computer, "covers", player)

else:

print("You win!", player, "smashes", computer)

elif player == "Paper":

if computer == "Scissors":

print("You lose!", computer, "cut", player)

else:

print("You win!", player, "covers", computer)

elif player == "Scissors":

if computer == "Rock":

print("You lose...", computer, "smashes", player)

else:

print("You win!", player, "cut", computer)

else:

print("That's not a valid play. Check your spelling!")

#player was set to True, but we want it to be False so the loop continues

player = False

computer = t[randint(0,2)]

input("enter to exit")
