Question

我尝试运行这个我在这个网站上找到它的Python程序，但是当我运行它没有任何反应时，我怎么能运行这个代码？我需要在代码中添加任何内容吗？我正在使用这个网站来运行它repl.it：非常感谢你。 ................

# The following is a database of problems, keywords, and solutions.
PROBLEMS = (('My phone does not turn on.',

if __name__ == '__main__':
    main()

Answer 1

在该网站repl.it上，在最终if之前，我添加了print(__name__)并获得了输出builtins。所以我们看到，当在repl.it上运行时，程序失败了__name__ == 'main'的非常重要的条件。

只需调用函数main，就可以修改程序使其在repl.it上工作只需更换程序的最后两行：

main()

Answer 2

如果您在该网站上运行该脚本，则需要自己调用main函数。在右栏中输入：

main()

使主函数执行。这被编译成字节代码，在那个网站上你基本上启动了解释器并导入了脚本，但你仍然需要调用该函数。

如果您所在的计算机上安装了python解释器，您实际上可以键入python name_of_file.py，然后通过在那里执行最后一个if语句来运行该脚本。

Answer 3

在你做了Aaron Mansheim所说的话之后，你需要提供一些意见。

点击＆＃39;输入＆＃39;在屏幕的右上角，然后键入脚本中提到的替代方案之一，如

My phone does not turn on.
yes

然后点击＆＃39;设置输入＆＃39;。然后再次运行代码。

顺便说一句，这可能是我学习如何使用Python代码的最慢的方法之一。您应该在您的计算机上安装Python并以该形式使用它。我的两分钱。

我试图运行我在这个网站上找到的这个程序，但它不起作用
