Python - AttributeError: 'str' object has no attribute 'append' - maths game

Trying to make it so a user can add a name, score and what difficulty the user completed the game on to high scores list.

def teacher_page():
    global scores, name, difficulties
    t_choice = None
    while t_choice !="0":
        print("\nWhat would you like to do?")
        print(
        """
        0 - Main Menu
        1 - Add a score
        2 - Remove a score
        3 - View highscores
        """
        )

        t_choice = input("Choice: ")
        print()

    #exit
        if t_choice == "0":
            main_menu()
    #add a score
        elif t_choice == "1":
            names = input("Name of the new user to add?\n")
            name.append(names)
            score = input("What did the user score?\n")
            scores.append(score)
            difficulty = input("And which difficulty did they complete it on?\n")
            difficulties.append(difficulty)
    #remove a score
        elif t_choice == "2":      
            names = input("Name of the user you want to remove?\n")
            if names in name:
                name.remove(names)          
            score = int(input("What did they score?\n"))
            if score in scores:
                scores.remove(score)
    #view highscores
        elif t_choice == "3":
            print("High Scores:")
            for score in scores:
                print(name, score, "on the difficulty ", difficulties)
    #if the t_choice does not = to 0,1,2,3
        else:
            print("Sorry but", t_choice, "isn't a vaild choice.")

But every-time I want to add a user to the list I get the error message 

AttributeError: 'str' object has no attribute 'append'

I've had a look at a few examples but not sure where I'm going wrong.

Initialize your variables as lists right below their declaration.

By default, when you assign raw input to them for the first time, they become strings.

Do something like:

global scores, name, difficulties
scores=[]
name=[]
difficulties=[]

During global declaration. Need not initialize again within the function.
