Refactoring is the process of incrementally improving the design/implementation of code while retaining its behaviour. An example of a particular refactoring is Extract Method, where a code fragment is turned into a separate method with a name which explains its purpose.


One of the simpler refactorings is Rename -- renaming a class or a method or a field to better reflect what it is. The point of using a tool to perform the renaming is that it should change all references so that the program continues to function afterwards.

Refactoring is easily done in statically-typed languages such as Java but it's somewhat harder in dynamically-typed languages such as Python.

Martin Fowler wrote a book on refactoring, called "Refactoring" ;) which is considered recommended reading. He also maintains a website on the subject: http://www.refactoring.com/.
