Software Refactoring Exercise
Chapter 1: Software refactoring exercise
Template Method pattern
Compare the FibonacciSequence and TriangleNumberSequence classes. There seems to be a lot of duplication, doesn’t it? Identify parts of the code that are similar, and parts that are different.
Make a copy of sequence.py and name it template.py.
Try to refactor the code in template.py to reduce the duplication using a Template Method pattern.
When you are done, run python3 template.py to make sure that your code is still behaving correctly.
