Why should you as a Data Scientist care about Software Engineering concepts?  Here we'll cover specific Software Engineering concepts and how these important ideas can revolutionize your Data Science workflow!

Python, data science, & software engineering

The big ideas

Python modularity in the wild

Introduction to packages & documentation

Installing packages with pip

Leveraging documentation

Conventions and PEP 8

Using pycodestyle

Conforming to PEP 8

PEP 8 in documentation

Software Engineering & Data Science

Become a fully fledged Python package developer by writing your first package!  You'll learn how to structure and write Python code that you can be installed, used, and distributed just like famous packages such as NumPy and Pandas.

Writing your first package

Minimal package requirements

Naming packages

Recognizing packages

Adding functionality to packages

Adding functionality to your package

Using your package's new functionality

Making your package portable

Writing requirements.txt

Installing package requirements

Creating setup.py

Listing requirements in setup.py

Writing a Python Module

Object Oriented Programming is a staple of Python development.  By leveraging classes and inheritance your Python package will become a much more powerful tool for your users.

Adding classes to a package

Writing a class for your package

Using your package's class

Adding functionality to classes

Writing a non-public method

Using your class's functionality

Classes and the DRY principle

Using inheritance to create a class

Adding functionality to a child class

Using your child class

Multilevel inheritance

Exploring with dir and help

Creating a grandchild class

Using inherited methods

Utilizing Classes

You've now written a fully functional Python package for text analysis!  To make maintaining your project as easy as possible we'll leverage best practices around concepts such as documentation and unit testing.

Documentation

Identifying good comments

Identifying proper docstrings

Writing docstrings

Readability counts

Using good function names

Using good variable names

Refactoring for readability

Unit testing

Using doctest

Using pytest

Documentation & testing in practice

Documenting classes for Sphinx

Identifying tools

Final Thoughts

Maintainability

Data scientists can experience huge benefits by learning concepts from the field of software engineering, allowing them to more easily reutilize their code and share it with collaborators. In this course, you'll learn all about the important ideas of modularity, documentation, & automated testing, and you'll see how they can help you solve Data Science problems quicker and in a way that will make future you happy. You'll even get to use your acquired software engineering chops to write your very own Python package for performing text analytics.
