Answer 1

Pass it as a parameter

def accounts():
    yourCode = input("Please enter your user code. 
If you already have an account, type your account user code. 
Otherwise, enter a new one to create an account: ")

   
    with open("users.txt", "r") as rf:
        users = rf.readlines() 
        for each_user in [user.split(",") for user in users]: 
            if each_user[0] == yourCode: 
                print(f"Welcome {each_user[1]}") 
                xxApp(each_user) 
                return None 
    ...


def xxApp(user):
    age = user[2]
    print(age)
