Start the program by calling the user function

user()

So im trying to make a simple appliacation for my school assignment where i have to make a trip planner and i have to create roles like admin , merchant , and traveler.so the admin has add function where he can add new merchants to access the merchant function. But everytime I try to sign with the new user the terminal freezes.
