英文:
Tkinter Label is missing - Python not working correctly?
问题
I'm trying to get started with Tkinter.
I wrote my first little piece of code. A window opens and a button appears, but the label is missing.
import tkinter as tk
def button_click():
label.config(text="Button was clicked!")
root = tk.Tk()
root.title('Test')
root.geometry('400x300')
root.pack_propagate(False)
label = tk.Label(root, text="Hello World!")
label.pack()
button = tk.Button(root, text="Click me!", command=button_click)
button.pack()
root.mainloop()
type here
The window is black with a white button.
When I just use the label without a button, the window turns white and is completely empty.
Just tried the code on a different device, and there it works.
I'm not sure, but I think something with my Python settings is wrong; maybe I installed it wrongly. I'm working in PyCharm.

来编辑：Op 使用 MacOS。
如果你正在使用 MacOS，请移除前缀 `tk.`
```python
from tkmacosx import Label, Button
import tkinter as tk
def button_click():
label.config(text="按钮被点击了！")
root = tk.Tk()
root.title('测试')
root.geometry('400x300')
root.pack_propagate(False)
label = Label(root, text="你好，世界！")
label.pack()
button = Button(root, text="点击我！", command=button_click)
button.pack()
root.mainloop()

If you are using MacOS. Then remove prefix tk.
from tkmacosx import Label, Button
import tkinter as tk
def button_click():
label.config(text="Button was clicked!")
root = tk.Tk()
root.title('Test')
root.geometry('400x300')
root.pack_propagate(False)
label = Label(root, text="Hello World!")
label.pack()
button = Button(root, text="Click me!", command=button_click)
button.pack()
root.mainloop()
