8.3 Good practices related to raising and handling exceptions

When writing code, it's important to be mindful of how you handle exceptions. You don't want to blindly catch every exception that may arise, as this can make it difficult to identify and address real programming errors. Instead, it's best to be selective and catch only those exceptions that you are specifically prepared to handle. This way, you can ensure that your code is robust, reliable, and easy to debug.

For instance, let's consider a few examples of exceptions that you might want to catch.
