How to Debug Common Python Errors - Real Python
Briefly

Debugging is an essential skill that entails identifying and resolving issues in code. It involves systematically examining code to find the root cause of problems. Techniques such as using print statements, setting breakpoints, and logging are commonly employed to debug effectively. When an error occurs, Python generates a traceback message that displays where the issue originated, including the file path and specific line number. Understanding tracebacks is crucial for quickly diagnosing errors and implementing solutions to ensure code functions correctly.
Debugging is the process of identifying, analyzing, and resolving issues, errors, or bugs in your code. It involves systematically examining code to determine the root cause of a problem.
When Python encounters an error during execution, it prints a traceback, which is a detailed message that shows where the problem occurred in your code.
Breaking down the traceback, the first part indicates a generic message sent by Python to notify you of a problem, followed by the file path and specific line where the error originated.
Debugging often involves using tools and techniques such as breakpoints, logging, and tests to achieve error-free and optimized performance of your code.
