Catch errors the right way: Python Error Handling
This talk will guide you through the essentials of effective error handling in Python, focusing on common pitfalls and best practices. You’ll learn how to target specific errors, use custom exceptions
In this talk, I will explore the essential principles of effective error handling in Python, focusing on common pitfalls and best practices. The session is designed to help developers write more robust, maintainable code by improving how exceptions are managed.
Key Topics Covered:
Targeting Errors Precisely: How to avoid wrapping unnecessary code in try/except blocks, ensuring that only the lines that may actually raise an exception are included.
Explicit Error Handling: The importance of catching specific exceptions rather than using broad, generic ones, leading to better debugging and code clarity.
Custom Exceptions: How to define and use custom exceptions to provide more meaningful error messages and context, making code easier to understand and maintain.
Motivation:
This talk was inspired by my experiences at work, where I’ve noticed that some errors pass silently or are raised without sufficient context. This leads to code that is difficult to debug and maintain, resulting in wasted time and resources. By addressing these issues, I aim to help educate people to write more reliable code that is easier to manage and troubleshoot.
