Did I miss something? I have no idea where I went wrong

So, I have written a simple login system program. But when I run the program, select an action, like Register, it just gets terminated. It doesn’t run the functions.

I’m so confused and I can’t figure out what’s wrong. Please help me. Thank you.

Here is the code:

import os
choice = ""

def login():
    global username_not_to_be_used
    global username

    username = input("Please enter your username: ")
    username_not_to_be_used = username
    file_check_L = os.path.isfile("C:/Users/Mercado Family/Desktop/JOSH FILES/" + username + " .txt")
    if file_check_L == False:
        print("Username doesn't exist.")
        start()
    elif file_check_L == True:
        def passwordCheck ():
            passw_check_L = open("C:/Users/Mercado Family/Desktop/JOSH FILES/" + username + " .txt","r")
            passw_L = input("Please enter your passwpord.")

            if passw_check_L != passw_L:
                print("Incorrect Password. Please try again.")
                passwordCheck()
            elif passw_check_L == passw_L:
                print("Welcome " + username)
def register():
    new_user = input("Please enter a new username: ")
    file_check_R = os.path.isfile("C:/Users/Mercado Family/Desktop/JOSH FILES/" + new_user + " .txt")
    if file_check_R == True:
        while file_check_R:
            print("This username already exist. Please enter a new one.")
            continue
    elif file_check_R == False:
        print("Your username is " + new_user)

    new_passw = input("Please enter your desired password: ")
    confirm_passw = input("Please confirm your password: ")

    if new_passw == confirm_passw:
        user_details = open("C:/Users/Mercado Family/Desktop/JOSH FILES/" + new_user + " .txt")
        user_details.write(new_passw)
        user_details.close()
        print("Your account as been created.")

        start()

    else:
        print("Error. Please try again.")
        start()

def start():
    print("1. Login")
    print("2. Register")
    print("3. Quit")
    choice = input("What do you want to do?")
    if choice == 1:
        print("Please login.")
        login()
    elif choice == 2:
        print("Please register.")
        register()
    elif choice == 3:
        print("Thank you, have a nice day.")
        quit()



start()

The variable ‘choice’ is a string not a number. Then the if statement is testing for a number.

print(type(choice))
<class 'str'>

Also, it is good to have an else statement to catch anything that does not fall within the if statements. You will never know what input you will get from users.

    if choice == 1:
        print("Please login.")
        login()
    elif choice == 2:
        print("Please register.")
        register()
    elif choice == 3:
        print("Thank you, have a nice day.")
        quit()
    else:
        print('Invalid input.')
