Modern Python Standard Library Cookbook

There's more...

More complete solutions for error reporting in web applications in Python are available out of the standard library. If you have further needs or want to get the errors notified by email or through cloud error reporting solutions, such as Sentry, you might want to provide an error reporting WSGI library.

The Werkzeug debugger from Flask, the WebError library from the Pylons project, and the Backlash library from the TurboGears project are probably the most common solutions for this purpose.

You might also want to check whether your web framework provides some advanced error reporting configuration, as many of them provide it out of the box, relying on those libraries or other tools.
