Commenting is essential in Python code because it serves as a method for explaining the code's functionality. Comments provide context for what specific sections of the code do, which can be especially helpful for anyone reading the code later, including the original author. By using comments, developers can describe the logic behind complex algorithms, note important decisions, and provide additional information that may not be immediately obvious from the code itself. This practice enhances readability and maintainability, allowing others (or the same developer at a later time) to quickly understand the purpose and flow of the code without needing to decipher every line.
Additionally, comments can be valuable during collaboration among team members, as they can clarify intentions and facilitate smoother communication about the codebase. Overall, well-commented code contributes to better software development practices and aids in the long-term management of the code.
