python - Tkinter-SyntaxError : non-keyword arg after keyword arg

Question

我有一个我无法理解的问题，因此在删除按钮中，尝试在创建按钮后将其删除的地方，出现以下错误:

Delete=Button(root,text='Delete',command=lambda : S.pack_forget(),T.pack_forget())
SyntaxError: non-keyword arg after keyword arg

码:

from Tkinter import *

root=Tk()
Menubar = Menu(root)
root.config(menu=Menubar)


def CreateButton():

    S=Button(root,text='Second Boton')
    S.pack(side='right')

    T=Button(root,text='Third Boton')
    T.pack(side='right')

    Delete=Button(root,text='Delete',command=lambda : S.pack_forget(),T.pack_forget())
    Delete.pack(side='right')


Create=Button(root,text='Create Boton',command=CreateButton)
Create.pack(side='left')

root.mainloop()

您必须在命令中放置“[]”才能访问使用多个命令。
只需从中进行编辑:

Delete=Button(root,text='Delete',command=lambda : S.pack_forget(),T.pack_forget())

至 :

Delete=Button(root,text='Delete',command=lambda : [S.pack_forget(),T.pack_forget()])
