🐞 Debugging and Error Handling: Your Ultimate Guide 🐞

Hey there, future AP Computer Science Principles rockstar! Errors, or as we like to call them, bugs, are a normal part of coding. Don't sweat it; everyone encounters them. This guide will help you understand, identify, and squash those bugs like a pro. Let's dive in!

πŸ” Common Errors

Here’s a breakdown of the usual suspects you'll encounter:

πŸ‘Ύ Syntax Errors

Key Concept

These occur when you break the grammatical rules of a programming language. Think of it like forgetting a period at the end of a sentence, or misspelling a word in English. The computer won't understand your instructions and will throw an error.

  • Examples:
    • Forgetting a closing parenthesis )
    • Misspelling a variable name
    • Incorrect indentation (especially in Python)
Exam Tip

Most code editors highlight syntax errors, making them relatively easy to spot and fix. Pay attention to those red squiggly lines!
