How to make input come after input if certain line inserted and if not runs OtherCode

[deanhystad]

You should not test for Adrian or mad or any other user name. You should take the name and then check if the name is valid. In this example I have a dictionary mapping user names to passwords.

users = {"Adrian":"Rocky", "mad":"world"}

def login():
    name = input("Username: ")
    password = input("Password: ")
    if users.get(name, None) == password:
        return name
    return None

if name := login():
    print(f"Welcome {name}")
else:
    print("Invalid username and/or password")

The idea is to avoid writing code for a particular case and instead write code that is generic. This code doesn't care who the users are or what the passwords are. All it cares about is that someone entered a username/password pair that matched an entry in the user database.
