Exception Chaining

When it comes to handling errors in your Python applications, the way you manage those errors can make a big difference in debugging and maintaining your code. One powerful concept in Python's exception handling arsenal is exception chaining.

This technique allows you to link exceptions together, providing a clearer picture of what went wrong and why. It’s especially useful in complex applications where errors can cascade through multiple layers of code.

Imagine working on a web application where a failure in one part of the system leads to errors in another. If you only capture the final error, you might miss the root cause. Exception chaining enables you to connect those dots, giving you a richer context when an error occurs.
