In Python, when you're trying to add information to an exception, it's essential to understand the nuances of how exceptions work. The issue arises because Python's built-in exception handling doesn't allow direct modification of exception attributes.

⚠️ Common Causes

  • Directly modifying an exception attribute in the `except` block.

✅ Best Solutions to Fix It

Method 1: Raising a New Exception with Additional Information

  1. Step 1: Create a new exception class that inherits from the original exception type, and add the desired information to it.

Method 2: Using Custom Exception Handling

  1. Step 1: Define a custom exception handling function that takes the original exception as an argument, and returns a new exception with the desired information.

✨ Wrapping Up

By using one of these methods, you can effectively add information to an exception in Python and achieve the desired behavior.
