Refactoring is the process of restructuring existing code without changing its external behavior.

Why Refactor?

Benefit	Description
Readability	Makes code easier to read and understand;
Maintainability	Simplifies updates and bug fixes;
Extensibility	Prepares code for future enhancements and new features;
Reduces Technical Debt	Lowers the cost of future changes and minimizes hidden issues.

Refactoring is not about:

• Adding new features;
• Fixing bugs;
• Changing the program's external behavior.

Focus on improving the internal structure of your code so that it is easier for you and others to work with.

The typical process for refactoring Python code follows a clear sequence. Each step has a specific purpose and helps ensure that your codebase becomes cleaner and safer to modify.

Step	Purpose
Identify	Find areas of the code that could be improved, such as duplicated logic, unclear variables, or complex functions;
Plan	Decide which refactoring techniques to use and break the work into manageable steps;
Perform Refactoring	Make incremental changes to improve the code structure without altering external behavior;
Test	Ensure that the code's behavior remains unchanged and that no new bugs are introduced.

By following this process, you make your codebase easier to understand, maintain, and extend while minimizing risk.
