Python Functions Forward Definitions

[Oliver123456]

So i am trying to make it possible so in one function it will define a variable, but above that i need another function to use that same variable (this is because i am calling that fiunction in the first function). How can I do this?

import re

def rollDieWithPoints():
   print("hi")
   print(user1)
   print(user2)
   print("hi again")

def authentication():
    file = open("users.txt")
    text = file.read()
    user1NameInput = input("What is your name user 1?: ")
    re_res = re.search(r'^{}, (.*)$'.format(user1NameInput), text, re.MULTILINE)
    if re_res:
        password = re_res.group(1)
        user1PasswordInput = input("What is you password user 1?: ")
        if password == user1PasswordInput:
           print("Welcome to the game user 1, now for user 2")
           user2NameInput = input("What is your name user 2?: ")
           re_res = re.search(r'^{}, (.*)$'.format(user2NameInput), text, re.MULTILINE)
           if re_res:
              password = re_res.group(1)
              userPasswordInput = input("What is you password user 2?: ")
              if password == userPasswordInput:
                 print("Welcome to the game, now you can both play")
                 user1 = user1NameInput
                 user2 = user2NameInput
                 rollDieWithPoints()
              else:
                 print("Wrong password, try again")
           else:
              newUsernameInput = input("That username is not in the system, would you like to create a new user by that name? (Y/N): ")
              if newUsernameInput == "Y":
                 file = open("users.txt", "a")
                 newUsernamePasswordInput = input("Please enter your password?: ")
                 file.write("\n" + userNameInput + ", " + newUsernamePasswordInput)
                 file.close()
              elif newUsernameInput == "N":
                 print("Okay, username incorrect, try again")
              else:
                 print("That is not an input, please try again")
        else:
            print("Wrong password, try again")
    else:
       newUsernameInput = input("That username is not in the system, would you like to create a new user by that name? (Y/N): ")
       if newUsernameInput == "Y":
          file = open("users.txt", "a")
          newUsernamePasswordInput = input("Please enter your password?: ")
          file.write("\n" + userNameInput + ", " + newUsernamePasswordInput)
          file.close()
       elif newUsernameInput == "N":
          print("Okay, username incorrect, try again")
       else:
          print("That is not an input, please try again")
    file.close()

def start():
    authentication()

start()

I want the initial definitions to happen in authentication() and then the use to happen in rollDieWithPoints().

 

Thanks!

# Define a function that takes two arguments
# user1 and user2.
def rollDieWithPoints(user1, user2):
  print(user1)
  print(user2)
  
# In your authentication method, you can simple call
# the rollDieWithPoints function, passing your two
# variables as the arguments.
def authentication():
  # ...
  if password == userPasswordInput:
    rollDieWithPoints(user1NameInput, user2NameInput)
  # ...

Thanks, i knew it was a simple solution but not exactly what the solution was!
