Python 电报机器人突然变得沉默

Question

我在 python-telegram-bot v20 库上有一个电报机器人。有时它会停止应答，我会收到此错误：

vThe above exception was the direct cause of the following exception:

如何防止此错误或至少使用错误处理程序处理它？

Answer 1

原因：只要你关闭计算机，你的代码就会停止运行。

为了防止这种情况，您可以在服务器上运行您的程序（此处：telegram chatbot），或者使用在线集成开发环境和网络托管服务，例如https://www.pythonanywhere.com/（我是更担心的是还有许多其他选择）。

另外，为了避免所有这些冗长的错误消息，只需使用

try ... except

捕获它即可。
