Question

试图让用户可以添加姓名，得分以及用户在高分榜上完成游戏的难度。

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.")

但是每次我想在列表中添加用户时都会收到错误消息

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

我看了几个例子，但不知道我哪里出错了。

Answer 1

将变量初始化为声明下方的列表。

默认情况下，当您第一次为其分配原始输入时，它们将成为字符串。

做类似的事情：

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

在全球宣布期间。无需在函数内重新初始化。

Python - AttributeError：'str'对象没有属性'append' - 数学游戏
