Question

以下是代码：

def StartGame():
    root = Tk()
    root.title("Maths Quiz - Trigonometry and Pythagoras' Theorem | Start The Game")
    root.geometry("640x480")
    root.configure(background = "gray92")
    TotScore = 0
    Count = 0
    while Count < 10:
        AnswerReply = None
        WorkingArea = Text(root, width = 70, height = 10, wrap = WORD).place(x = 38, y = 100)
        n = GetRandomNumber
        Question,RealAnswer = QuestionLibrary(Opposite,Adjacent,Hypotenuse,Angle,n)
        AskQuestion = Label(root, text = Question).place(x = 38, y = 300)
        PauseButton = ttk.Button(root, text = "Pause").place(x = 380, y = 10)
        HelpButton = ttk.Button(root, text = "Help", command = helpbutton_click).place(x = 460, y = 10)
        QuitButton = ttk.Button(root, text = "Quit", command = root.destroy).place(x = 540, y = 10)
        AnswerEntry = Entry(root)
        AnswerEntry.place(x = 252, y = 375)
        SubmitButton = ttk.Button(root, text = "Submit", command = submit_answer).place(x = 276, y = 400)
        Count += 1
    root.mainloop()

这是与提交按钮一起使用的功能：

def submit_answer():
    Answer = AnswerEntry.get()
    print(Answer)
    TotScore,AnswerReply = IsAnswerCorrect(Answer,RealAnswer)
    ScoreLabel = ttk.Label(root, text = TotScore).place(x = 10, y = 10)
    AnswerReplyLabel = ttk.Label(root, text = AnswerReply).place(x = 295, y = 440)

这是我点击SubmitButton

时得到的错误

Traceback (most recent call last):
  File "C:\Python32\lib\tkinter\__init__.py", line 1399, in __call__
    return self.func(*args)
  File "C:\Users\ANNIE\Documents\School\Computing\Project\Python\GUI Maths Quiz.py", line 178, in submit_answer
    Answer = AnswerEntry.get()
AttributeError: 'int' object has no attribute 'get'

我正在尝试制作一个测验游戏，我使用AnswerEntry Entry框从用户那里获得输入，但它告诉我该对象没有属性获取，请帮忙！

Answer 1

如果您希望AnswerEntry = Entry(root)行影响在函数外部定义的全局名称，则需要将其声明为StartGame()函数内的全局名称：

global AnswerEntry
AnswerEntry = Entry(root)

对函数中变量的赋值使该变量名仅作为函数的局部。您似乎已在其他地方为全局AnswerEntry分配了一个整数值，因此submit_answer()会在您致电AnswerEntry.get()时看到。

你应该真的避免使用全局变量。

Answer 2

AnswerEntry是一个整数，而不是一个对象，所以你不能在他身上调用该方法。

也许你错过了对象实例？

AttributeError：'int'对象没有属性'get'
