If your project includes a Pylint configuration file, the settings contained in that file take precedence. To find out more about Pylint, please refer to their site.

Catching very general exceptions such as
Exception is usually not recommended.
Generally, you would want to handle very specific errors in the exception handler. This ensure that you do not hide other types of errors which should be fixed. So, unless you specifically plan to handle any error, consider adding a more specific exception.
