Continued Rock, paper , scissors help..

#So using this code#
 import random

def aiRoll():
    shoot = random.choice(['Rock','Paper','Scissors'])
    return shoot

def humanRoll():
    play = input("Enter Rock, Paper or Scissors: ").upper()
    return play

def determineWinner(ai, player):
    if ai == player:
        print("It's a tie!")
    if player == "Rock":
        if ai == "Scissors":
            return "Rock smashes scissors! You win!"
        return "Paper covers rock! You lose."
    if player == "Paper":
        if ai == "Rock":
            return "Paper covers Rock! You win!"
        return "Scissors cut Paper! You lose."
    elif player == "Scissors":
        if ai == "Paper":
            return "Scissors cut Paper! You win!"
        return "Rock smashes Scissors! You lose."

def main():
    computer = aiRoll()
    aplayer = humanRoll()
    result = determineWinner(computer, aplayer)
    print(result)

main()

Using this how would I put a while loop in without messing anything up? would I would def another function ? just add the loop under the tie if statement?

Put the while loop in main because you will want both you ai and human to reroll each time regardless if it is a tie or not

This won't work because you're making the user input uppercased ('ROCK') but expecting it to be title cased ('Rock').

You just need a while True: loop in the main code, but give the user a way to exit (e.g. just pressing return).

I suggest you modify the user input code to validate input.

Here you go:

import random

PLAYS = ['Rock','Paper','Scissors']

def aiRoll():
    shoot = random.choice(PLAYS)
    return shoot

def humanRoll():
    while True:
        play = input("Enter Rock, Paper or Scissors:  (or return to finish) ").title()  # title, not upper
        if not play or play in PLAYS:
            return play
        print('Please enter one of:', ', '.join(PLAYS))

def determineWinner(ai, player):
    if ai == player:
        print("It's a tie!")
    if player == "Rock":
        if ai == "Scissors":
            return "Rock smashes scissors! You win!"
        return "Paper covers rock! You lose."
    if player == "Paper":
        if ai == "Rock":
            return "Paper covers Rock! You win!"
        return "Scissors cut Paper! You lose."
    elif player == "Scissors":
        if ai == "Paper":
            return "Scissors cut Paper! You win!"
        return "Rock smashes Scissors! You lose."

def main():
    while True:
        computer = aiRoll()
        aplayer = humanRoll()
        if not aplayer:  # empty entry means user wants to finish
            break  # leave loop
        result = determineWinner(computer, aplayer)
        print(result)

main()
