有人知道为什么我的tkinter按钮没有显示吗？

Question

这是针对GitHub上的python项目的，我正在为Magic 8 Ball模拟制作GUI。我似乎无法使用.pack（）函数，或者我的窗口永远加载而无需实例化。

When created

When I click a button the text appears

window = Tk()
window.configure(bg="black")
window.title("Magic 8 Ball")
Label(window, text="Ask the Magic 8 Ball the question on your mind or enter X to exit: ", bg="black", fg="white")\
    .grid(row=0, column=0)


# Create entry box to type question
entrybox = Entry(window, width=30, bg="white")
entrybox.grid(row=1, column=0)


# Create output box at below buttons
output = Text(window, bg="white", fg="black", width=40, height=5)
output.grid(row=4, column=0)


# Create 4 button: Ask, Clear, Play Again, Quit
button_frame = Frame(window)
button_frame.configure(bg="black")
button_frame.grid(row=2, column=0)

#button_frame.pack(fill=X, side=BOTTOM)
Button(button_frame, text="Ask", width=10, bg="black", fg="white", command=click).grid(row=2, column=0)
Button(button_frame, text="Clear", width=10, command=clear).grid(row=2, column=1)
Button(button_frame, text="Play Again", width=10,command=repeat).grid(row=3, column=0)
Button(button_frame, text="Quit", width=10, command=close).grid(row=3, column=1)


window.mainloop()

我认为我们将需要有关您的操作系统和python版本的更多规范。我在Python 3.5.0和Windows 10上运行了它，结果是：

因此，我认为这不是您的代码中的错误。我确实必须添加所有功能并导入您丢失的东西，所以我运行的结果看起来像这样：

from tkinter import *
window = Tk()
def click():
    print('click')
def clear():
    print('clear')
def repeat():
    print('repeat')
def close():
    print('close')
window.configure(bg="black")
window.title("Magic 8 Ball")
Label(window, text="Ask the Magic 8 Ball the question on your mind or enter X to exit: ", bg="black", fg="white")\
    .grid(row=0, column=0)


# Create entry box to type question
entrybox = Entry(window, width=30, bg="white")
entrybox.grid(row=1, column=0)


# Create output box at below buttons
output = Text(window, bg="white", fg="black", width=40, height=5)
output.grid(row=4, column=0)


# Create 4 button: Ask, Clear, Play Again, Quit
button_frame = Frame(window)
button_frame.configure(bg="black")
button_frame.grid(row=2, column=0)

#button_frame.pack(fill=X, side=BOTTOM)
Button(button_frame, text="Ask", width=10, bg="black", fg="white", command=click).grid(row=2, column=0)
Button(button_frame, text="Clear", width=10, command=clear).grid(row=2, column=1)
Button(button_frame, text="Play Again", width=10,command=repeat).grid(row=3, column=0)
Button(button_frame, text="Quit", width=10, command=close).grid(row=3, column=1)


window.mainloop()
