I want to make a rock-paper-scissors program

from tkinter import *
import random as r

def GBB() :
    global com
    com = random.randint(1,3)


def vs() :
    if com==user :
        print ("It's a tie!" Rock-paper-scissors again!")
    else com==1 :
        if user==2 :
        print("I won! I'll go up 1 space~")
    else com==1 :
        if user==3 :
        print ("I lost...")
    else com==2 :
        if user==1 :
        print ("I lost...")
    else com==2 :
        if user==3 :
        print("I won! I'll go up 3 spaces~")
    else com==3 :
        if user==1 :
        print("I won! I'll go up 2 spaces~")
    else com==3 :
        if user==2 :
        print ("I lost...")

    path1 = PhotoImage (file = "left scissors.gif")
