PLZ HELP!!! I'm a beginner in coding!
Lina20 [59]

import random

rock,paper,scissors = 1,2,3

choice = int(input("Please choose 1 2 or 3: "))

computer = random.randint(1,3)

player_won = False

draw = False

if choice == computer:

   draw = True

elif choice == 1 and computer == 3:

   player_won = True

elif choice == 2 and computer == 1:

   player_won = True

elif choice == 3 and computer == 2:

   player_won = True

if player_won:

   print("You won!")

elif not player_won and not draw:

   print("The computer won!")

else:

   print("It's a draw!")

First, I recommend importing at the beginning of your program. Also, you can combine all your same datatype variables in one line. You also need to cast your user choice to an integer so you can compare it with the computer's choice. I wrote the if, elif, and else statements using a boolean variable. I simply wrote all the possibilities that would result in the player winning and this would result in the player_won variable being true. If this is the case, we print to the console, "You won!"
