Refactor your legacy code base

Python is currently used in many different areas such as software construction, systems administration, and data processing. In all of these areas, experienced professionals can find examples of inefficiency, problems, and other perils, as a result of bad code. After reading this book, readers will understand these problems, and more importantly, how to correct them.

This book covers the following exciting features:Set up tools to effectively work in a development environmentExplore how the magic methods of Python can help us write better codeExamine the traits of Python to create advanced object-oriented designUnderstand removal of duplicated code using decorators and descriptorsEffectively refactor code with the help of unit testsLearn to implement the SOLID principles in Python

Setup

Create a virtual environment, and once activated run:

make setup

This will install the common dependencies. Besides this, each chapter mighthave additional ones, for which anothermake setup will have to be runinside that particular directory.

Each chapter has its corresponding directory given by its number.

Inside each chapter directory, tests can be run by:

make test

This requires themake application installed (in Unix environments).In environments without access to themake command, the same code can betested by running the commands on theMakefile:

python -m doctest *.pypython -m unittest *.py

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

class Point:    def __init__(self, lat, long):        self.lat = lat        self.long = long

• In Chapter 2, page 41: Add the following import in the code:from datetime import date

Following is what you need for this book:This book will appeal to team leads, software architects and senior software engineers who would like to work on their legacy systems to save cost and improve efficiency. A strong understanding of Programming is assumed.

With the following software and hardware list you can run all code files present in the book (Chapter 1-10).
