Python中tkinter中控件的使用（7,Menu顶层菜单栏)

import tkinter

win = tkinter.Tk()
win.title("Menu顶层菜单栏")
win.geometry("800x600+600+100")

#菜单条
menubar =tkinter.Menu(win)
win.config(menu=menubar)
def func():
    print("lalaa")
#创建一个菜单选项
menu1=tkinter.Menu(menubar,tearoff=False)
#给菜单选项，添加菜单内容
for item in ["Python","C","C++","OC","Swift","C#","shell",
             "java","JS","PHP","汇编","NodeJs","退出"]:
    if item=="退出":
        menu1.add_separator()#添加一个分割线
        menu1.add_command(label=item,command=lambda :win.quit())#lambda:win.quit==win.quit
    else:
        menu1.add_command(label=item,command=func)
#向菜单条上添加菜单
menubar.add_cascade(label="语言",menu=menu1)

menu2=tkinter.Menu(menubar,tearoff=False)
menu2.add_command(label="red")
menu2.add_command(label="blue")
menubar.add_cascade(label="颜色",menu=menu2)



win.mainloop()
