英文:

Why is tkinter not displaying anything?

问题

我正在尝试使用tkinter制作一个UI游戏，但在打开的窗口中没有显示任何内容，在shell中也没有错误。

```python
import tkinter as tk

count = 0

def on_button_click():
    global count
    count += 1
    label.config(text="You have clicked " + str(count) + " times!")

root = tk.Tk()
root.title("My Game")
root.geometry("800x600")

# button
button = tk.Button(root, text="Click me", command=on_button_click)
button.pack()

# label
label = tk.Label(root, text="Jitter click the button")
label.pack()

root.mainloop()

脚本的输出

我尝试过搜索不同的tkinter教程，但它们都表现得一样，是否有明显的遗漏。

你的标签和按钮创建代码位于root.mainloop()之外，并且你有两次mainloop()行。

Your label &amp; button creation code is outside your root.mainloop() and you have the mainloop() line twice.
