Python Basics: Finding and Fixing Code Bugs

Python

Everyone makes mistakes—even seasoned professional developers!

IDLE is pretty good at catching mistakes like syntax errors and run-time errors, but there’s a third type of error that you may have already experienced. Logic errors occur when an otherwise valid program doesn’t do what was intended.

Logic errors cause unexpected behaviors called bugs. Removing bugs is called debugging, and a debugger is a tool that helps you hunt down bugs and understand why they’re happening.

Knowing how to find and fix bugs in your code is a skill that you will use for your entire coding career!
