How to start the program from the beginning.

[iamaghost]

Hey guys,

im currently just trying to make very basic rock, paper, scissors game but i strumbled upon the following problem:

i wrote basic code to play Rock, Paper, Scissors. After every round i call the playagain() function to ask the user, if he wants to play again. If he does, i want the code to start over again.

Heres my Code:

import random



# user input
# random cpu for R,S,P
# compare results
# print winner
# Ask to play again

def playagain():
    print("do you want to play again?")
    choose = input("Yes or No?")
    choose = choose.upper()
    if choose == "YES":
        print("a") # THE PROBLEM IS HERE: IF THE USER INPUT EQUALS "YES", THEN START FROM THE BEGINNING
    else:
        exit()


# cpu options to randomly choose
options = ["R", "P", "S"]
cpu = [i for i in random.choice(options)]
cpu = cpu[0]

user = input("Choose [R]ock, [P]aper or [S]cissors: ").upper()

# What if user gives wrong input?
while user not in options:
    user = input("Choose [R]ock, [P]aper or [S]cissors: ").upper()

if cpu == user:
    print("Draw!")
elif user == "R" and cpu == "S":
    print("You Win!")
    playagain()
elif user == "R" and cpu == "P":
    print("Fucking looser. You Suck!")
    playagain()
elif user == "P" and cpu == "R":
    print("You Win!")
    playagain()
elif user == "P" and cpu == "S":
    print("you fucking suck!")
    playagain()
elif user == "S" and cpu == "R":
    print("you suck!")
    playagain()
elif user == "S" and cpu == "P":
    print("You Win!")
    playagain()

thanks ahead!
