How do I start from the beginning of the code while keeping the string value?

I need to go to line 14 of this code after the code has finished running. How would I do that?

from replit import db
import getpass
import sys

def signup():
    db["User"] = input("Enter username:\n")
    db["Pass"] = getpass.getpass("Enter Password:\n")


def login():
    print("WIP")


LorS = int(input("Login or Signup? (0 for login, 1 for Signup)\n")) # line 14

if LorS == 1:
    signup()
elif LorS == 0:
    login()
else:
    sys.exit()

>Solution :

You loop it and then exit whenever you want to.

from replit import db
import getpass
import sys
def signup():
   db["User"] = input("Enter username:\n")
   db["Pass"] = getpass.getpass("Enter Password:\n")
def login():
   print("WIP")
while True:  # you loop until you want to exit ---------
   LorS = int(input("Login or Signup? (0 for login, 1 for Signup)\n"))

   if LorS == 1:
       signup()
   elif LorS == 0:
       login()
   elif LorS != 1 or 2:
       sys.exit()
