How to Create a Custom Exception in Python

In my journey as a Python developer, I've found that creating custom exceptions can significantly enhance error handling in your applications. Here are the steps to create your own exception class:

1. Define your custom exception: Inherit from the built-in Exception class.

   class MyCustomError(Exception):
       pass
   

2. Raise your exception: Use raise to trigger your custom exception where needed in your code.

   def risky_operation():
       raise MyCustomError("Something went wrong!")
   

3. Catch your exception: Use a try-except block to handle your custom exception.

   try:
       risky_operation()
   except MyCustomError as e:
       print(f"Caught an error: {e}")
   

🌟 Benefits of Custom Exceptions:
- Improved readability of your code 👀
- Specific error handling tailored to your application's needs
- Easier debugging 🐞

Embrace custom exceptions to build more robust Python applications! 💪
