Practical case: Create a window

We can use the Tkinter library to create a simple window:

import tkinter as tk

# 创建一个主窗口
root = tk.Tk()

# 设置窗口标题
root.title("My Window")

# 设置窗口大小
root.geometry("300x200")

# 创建一个标签
label = tk.Label(root, text="Hello, Python!")
label.pack()

# 启动窗口事件循环
root.mainloop()

Running this code will create a window called "My Window" containing a label that displays the text "Hello, Python!"
