Rock Paper Scissors Python Program: winOrLose() takes two arguments (0 given)

I am writing a program that plays Rock Paper Scissors with the user. I have to run the program 5 times. And I am using python. Whenever I run the program and type in "R", "S", or "P", the program would result in an error:

TypeError: winOrLose() takes exactly 2 arguments (0 given)  

This is my program below:

from myro import *  
from random import *  

def userOptions():  
    print "Press R for Rock"  
    print "Press P for Paper"
    print "Press S for Scissors"

choice = raw_input("Your choice is: ")

if choice == "R":
    return "Rock"
if choice == "P":
    return "Paper"
if choice == "S":
    return "Scissors"
else:
    userOptions()


def computerRandom():
    options = ["Rock", "Paper", "Scissors"]
    cGuess = randint(0,2)
    return options[cGuess]

def winOrLose(userChoice, computerChoice):
    if userChoice == computerChoice:
        return "Tie"
    if userChoice == "Rock" and computerChoice == "Paper":
        return "Computer Wins"
    if userChoice == "Paper" and computerChoice == "Scissors":
        return "Computer Wins"
    if userChoice == "Scissors" and computerChoice == "Rock":
        return "Computer Wins"
    else:
        return "User Wins"

    while True:
        userChoice = userOptions()
        computerChoice = computerRandom()
        print "User Chose: ", userChoice
        print "Computer Chose: ", computerChoice
        result = winOrLose(userChoice, computerChoice)
        if result == "Tie":
            print "It is a tie"
        elif result == "Computer Wins":
            print "Computer Wins"
        else:
            print "User Wins"

def main():
    for index in range(1,5,1):
        speak("Rock Paper Scissors Shoot")
        userOptions()
        computerRandom()
        winOrLose()

main()

Please someone help me, I am kinda desperate at this moment to figure out how to fix this problem.

Thank you
