Everyone makes mistakesβeven seasoned professional developers!
IDLE is pretty good at catching mistakes like syntax errors and run-time errors, but thereβs a third type of error that you may have already experienced. Logic errors occur when an otherwise valid program doesnβt 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 theyβre happening.
Knowing how to find and fix bugs in your code is a skill that you will use for your entire coding career!
In this Python Basics video course, youβll:
- Learn how to use IDLEβs Debug Control window
- Practice debugging on a buggy function
- Learn alternative methods for debugging your code
