Day19 参加职训(机器学习与资料分析工程师培训班)，Python程序设计

上午:Python程序设计

延续上次的tkinter，制作Menu有下拉式选单的功能

import tkinter as tk

def Hello():
    print('hello')

base = tk.Tk()
Menu01 = tk.Menu(base)

Submenu01 = tk.Menu(Menu01, tearoff = 0)
Submenu01.add_command(label = 'New File', command = Hello)
Submenu01.add_command(label = 'Open', command = Hello)
Submenu01.add_command(label = 'Save', command = Hello)
Submenu01.add_separator()
Submenu01.add_command(label = 'Exit', command = base.quit)
Menu01.add_cascade(label = 'File',menu = Submenu01)

Submenu02 = tk.Menu(Submenu01, tearoff = 0)
Submenu02.add_command(label = 'Cut', command = Hello)
Submenu02.add_command(label = 'Copy', command = Hello)
Submenu02.add_command(label = 'Paste', command = Hello)
Submenu02.add_command(label = 'Select All', command = Hello)
Submenu02.add_separator()
Submenu02.add_command(label = 'Find...', command = Hello)
Submenu02.add_command(label = 'Find again', command = Hello)
Menu01.add_cascade(label = 'Edit',menu = Submenu02)

Submenu03 = tk.Menu(Menu01, tearoff = 0)
Submenu03.add_command(label = 'TK Help', command = Hello)
Submenu03.add_command(label = 'Demo', command = Hello)
Submenu03.add_separator()
Submenu03.add_command(label = 'About TK', command = Hello)
Menu01.add_cascade(label = 'Help',menu = Submenu03)

base.config(menu = Menu01)
base.mainloop()

查询即时PM 2.5
