Python Basics: Finding and Fixing Code Bugs

Writing code is only half the battle; knowing how to fix it when it breaks is what makes you a true programmer. This text-based course guides you through the essential process of identifying, understanding, and resolving errors in your Python programs. You will transition from feeling frustrated by error messages to confidently reading tracebacks and systematically diagnosing bugs. By learning how the Python interpreter communicates, you will build the mental models necessary to write cleaner, more resilient code. What you'll learn: - Understand common Python error types, including SyntaxError, TypeError, and NameError. - Read and interpret Python tracebacks to locate the exact source of a bug. - Apply systematic debugging techniques to isolate and resolve logical errors. - Use modern type hints and basic testing principles to prevent bugs before they happen. - Practice troubleshooting common beginner mistakes through structured written exercises. The course begins with foundational definitions of bugs and errors, introducing you to the Python interpreter's feedback system. You will then progress to reading tracebacks, analyzing code logic, and adopting preventative coding habits. Designed specifically for beginner Python programmers who want to build confidence in troubleshooting, this course requires no prior debugging experience.
