Solving a Tennis Refactoring Challenge in Python using SOLID | by Tomer Gabay | Feb, 2024

Introduction

Code refactor challenges are well-known by software program program engineers, nonetheless a lot much less so by data scientists, though data scientists can also extraordinarily revenue from practising such challenges. By practising these, notably when making use of the SOLID guidelines, you uncover methods to put in writing considerably higher code; code that’s modular, of high quality and object-oriented. Mastering the SOLID guidelines as an data scientist can significantly elevate the usual and manageability of data science duties. That’s notably important in teams by which most data scientists are statisticians and mathematicians by origin, who might have a lot much less familiarity with programming fundamentals than software program program engineers.

There are numerous refactoring challenges accessible on-line. Possibly basically essentially the most well-known one is the Gilded Rose Kata. One different pleasing refactoring kata is the Tennis Refactoring Kata, which we’ll type out on this text.

Sometimes these challenges are referred to as katas, Inside the context of a “refactoring kata,” the phrase “kata” is borrowed from martial arts, the place it refers to a structured observe routine. In martial arts, a kata is a sequence of actions and techniques that are practiced repeatedly to reinforce expertise and fluency.

Go to https://github.com/emilybache/Tennis-Refactoring-Kata and select “Use As Template” inside the inexperienced prime correct button.

Clone the template and enter the repository in your terminal. Then, cd into the python itemizing, create a digital setting and arrange the dependencies. To examine if each little factor works run pytest. You’ll be capable of copy-paste the directions below into your terminal.

cd python
python -m venv .venv
provide .venv/bin/activate # on mac or linux
# .venvScriptsactivate # on residence home windows
pip arrange -r requirements.txt
pytest
