Python Tkinter 错误对象没有属性

所以我正在制作一个类似于街机游戏的程序。我希望在单击框架后 labelGuess 出现在顶层窗口中，但它给了我这个错误:

AttributeError: 'Window' 对象没有属性 'window'

这是代码:

from tkinter import *
from tkinter import font
import time

class Window(Frame):

    def __init__(self, master):

        Frame.__init__(self, master)
        self.master = master

        master.title("Arcade Games")
        master.geometry("800x600+560+240")

        b = Button(self, text="Guess the number", command=self.new_window)
        b.pack(side="top")
        self.customFont = font.Font(master, font="Heraldica", size=12)

        self.guess_number()

    def new_window(self):

        id = "Welcome to the 'Guess your number' game!\nAll you need to do is follow the steps\nand I will guess your number!\n\nClick anywhere to start!"
        self.window = Toplevel(self.master)
        frame = Frame(self.window)
        frame.bind("<Button-1>", self.guess_number)
        frame.pack()
        self.window.title("Guess the number")
        self.window.geometry("400x300+710+390")
        label = Label(self.window, text=id, font=self.customFont)
        label.pack(side="top", fill="both", padx=20, pady=20)

    def guess_number(self):


        labelGuess = Label(self.window, text="Pick a number between 1 and 10", font=self.customFont)
        time.sleep(2)
        labelGuess.pack(fill=BOTH, padx=20, pady=20)

if __name__ == "__main__":
    root = Tk()
    view = Window(root)
    view.pack(side="top", fill="both", expand=True)
    root.mainloop()

最佳答案

在您按下按钮并触发 guess_number 事件回调之前，您在初始化方法中对 new_window 的初始调用可能已被调用。在 guess_number 中，您试图将 self.window 作为参数传递给 Label() 但当时它是未定义的。
