pip install tk

import tkinter as tk

# 创建主窗口
root = tk.Tk()
root.title("我的第一个Tkinter程序")

# 创建标签
label = tk.Label(root, text="Hello Tkinter!")

# 启动主循环
root.mainloop()

import tkinter as tk

root = tk.Tk()
root.title("界面布局示例")

# 创建标签和按钮
label = tk.Label(root, text="这是一个标签")
label.pack()

button = tk.Button(root, text="点击我")
button.pack()

root.mainloop()

import tkinter as tk

root = tk.Tk()
root.title("事件处理示例")

button = tk.Button(root, text="点击我显示文本", command=show_text)
button.pack()

result_label = tk.Label(root, text="")
result_label.pack()

root.mainloop()

entry = tk.Entry(root)
entry.pack()

check_button = tk.Checkbutton(root, text="选择我")
check_button.pack()

radio_button = tk.Radiobutton(root, text="选项1")
radio_button.pack()

listbox = tk.Listbox(root)
