Question

我正在尝试运行一些代码并执行：

Core().Run()

然而我收到错误：

您的计划出错语法无效

并在

之后

Core().Run()

是空闲时的长红色条。有关如何运行程序的任何帮助吗？

完整代码：

    Core().Run()

Answer 1

你有一个没有except子句的大型try块;由于最后一行是Core().Run()，因此发生错误。

它认为你想要做的是：

import os
import sys
import mp3play
try:
    # for Python2
    from Tkinter import *
except ImportError:
    from tkinter import *

# The rest of your code here

语法Core（）无效。在Python中运行（）
