I know there is probably a simple solution to this, but the text I wrote under the elif sections in userName and passWord will not print when a user successfully logs in. Please help!

def userName():
    username = "kate"
    userInput = input('Please enter your username:\n')

    while userInput != username:

        if len(userInput) == 0:
            print("Your username can not be blank, please try again!\n")
            userInput = input('Please enter your username.\n')
        elif userInput == username:
            print("Welcome back, "   username)
            print("")
            break
        else:
            print("Sorry, that username is not in our system. Please try again!\n")
            userInput = input('Please enter your username.\n')

def passWord():
    password = "stags"
    passInput = input("Please enter your password:\n")

    while passInput != password:

        if len(passInput) == 0:
            print("Your password can not be blank, please try again!\n")
            passInput = input("Please enter your password.\n")
        elif passInput == password:
            print("You have successfully logged in!\n")
            break
        else:
            print("Sorry, your password is invalid. Please try again!")
            passInput = input("Please enter your password.\n")

def main():
    print("Hello, let's get started!")
    print("")
    userName()
    passWord()

main()

This was pointed out in the comments above, but if you change

while userInput != username:

and

while passInput != password:

to

while True:

it should work just fine. Then it forces your code to hit the elif statement rather than breaking the loop before printing what you want to say.

CodePudding user response：

In python indentation indicates where a code block starts and begins. So in your while loop in passWord() your if..elif..else must be indented exactly one tab in eg.

    while passInput != password:

        if len(passInput) == 0:
            print("Your password can not be blank, please try again!\n")
            passInput = input("Please enter your password.\n")
        elif passInput == password:
            print("You have successfully logged in!\n")
            break
        else:
            print("Sorry, your password is invalid. Please try again!")
            passInput = input("Please enter your password.\n")

Notice how the indentation always goes one tab in for each code block you want to create.
