Python“ Def”无效语法

Question

I am kinda new to python and I only been learning it for about a week. I am writing some script and I am using two def statements and it will say Invalid syntax fro the first def of the two defs

Here is the code:

from tkinter import *
import tkinter.messagebox

master = Tk()
def continue():
    answer = tkinter.messagebox.askquestion('Error 408!', 'Something went wrong here. Click terminate to quit the app')
    if answer == 'Yes':
        quit()

dlabel = Label(text='Pick a Button').pack()
master.title('Uselessapp')
master.geometry('200x200')

button = Button(master, text="Play Game", command=continue)
button.pack()

mlabel = Label(text='--------').pack()

def quitapp():
    quit()

button = Button(master, text="Quit", command=quitapp)

button.pack()

mainloop()

Please help!

Answer 1

您正在使用关键字作为函数名称，这是Python保留无法使用的名称.Python中有一个实际的关键字称为`` continue ''。您为函数使用了另一个名称，一个不是关键字的名称。

Answer 2

You have named your function continue which is a reserved word in python

The following identifiers are used as reserved words, or keywords of the language, and cannot be used as ordinary identifiers.

False      class      finally    is         return
None       continue   for        lambda     try
True       def        from       nonlocal   while
and        del        global     not        with
as         elif       if         or         yield
assert     else       import     pass
break      except     in         raise
