def on_select(event):
    selected_value = event.widget.get()
    print("Selected:", selected_value)

root = tk.Tk()

# 创建菜单
menu = tk.Menu(root)

# 创建下拉菜单
dropdown_menu = tk.Menu(menu, tearoff=0)

# 添加选项到下拉菜单
dropdown_menu.add_command(label="Option 1", command=lambda: print("Option 1 selected"))
dropdown_menu.add_command(label="Option 2", command=lambda: print("Option 2 selected"))
dropdown_menu.add_command(label="Option 3", command=lambda: print("Option 3 selected"))

# 将下拉菜单添加到菜单中
menu.add_cascade(label="Options", menu=dropdown_menu)

# 将菜单添加到窗口中
