Question

我使用Tkinter编写了很长的代码，但是根本无法使用。我不断收到一条巨大的错误消息，然后出现一个Python选项卡，告诉我它已崩溃。我在Pycharm上尝试过，通常在Terminal上尝试过，但都没有用。（Mac）

我不确定这个问题，所以我不断缩小范围。我已经确定的是，每当我在函数中使用入口小部件时，代码都会崩溃。这在我的PC上有效，但在我的mac上不起作用。香港专业教育学院尝试使用Conda，并更新Python，但我是一个真正的初学者，所以我不知道我在做什么。

from tkinter import *
from tkinter import Tk, Button, Frame, Entry, END


def the_graph():
    yeet = entry_1.get()
    return yeet

my_window = Tk()



button_1 = Button(my_window, text=" Just work please. ", command=the_graph)

label_1 = Label(my_window, text=" Label 1")
entry_1 = Entry(my_window)


label_1.grid(row=0, column=0)
entry_1.grid(row=0, column=1)
button_1.grid(row=29, column=0)

my_window.title('my window')
my_window.mainloop()

出现错误消息：

为什么在我的函数中输入Entry Widget会使python完全崩溃？
