Rock,paper,scissors Tally counter python [closed]

I have fixed your code . . .

from random import randint

print ("Rock ,Paper,Scissors game.")

#Function to get computer input
def generate():
    comlist = ["rock","paper","scissors"]
    comans = comlist[randint(-1,2)]
    if comans == "rock":
        print ("Computer choose rock.")
    elif comans == "paper" :
        print ("Computer choose paper.")
    elif comans == "scissors":
        print ("Computer choose scissors.")
    return comans

#Function to get user input
def user():
    userchoice = input ("Choose rock, paper , or scissors.")
    while userchoice != 'rock' and userchoice != 'paper' and userchoice != 'scissors':
        print ("Invalid input. Please enter again")
        userchoice = input ("Choose rock, paper , or scissors.")
    if userchoice == "rock":
        print ("You  choose rock.")
        choice = userchoice
    elif userchoice == "paper" :
        print ("You choose paper.")
        choice = userchoice
    else:
        userchoice == "scissors"
        print ("You choose scissors.")
        choice = userchoice
    return choice

#Function to determine winner
def result(comans ,choice):
    result_set=""
    if choice == comans:
        print ("Tie")
    elif choice == "rock":
        if computer == "paper":
            print ("You lose")
        else :
            print("You win")
            result_set="win"
    elif choice == "paper":

        else:
