The Data Wrangling Workshop - Second Edition

By: Brian Lipp, Shubhadeep Roychowdhury, Dr. Tirthajyoti Sarkar

Overview of this book

While a huge amount of data is readily available to us, it is not useful in its raw form. For data to be meaningful, it must be curated and refined. If you’re a beginner, then The Data Wrangling Workshop will help to break down the process for you. You’ll start with the basics and build your knowledge, progressing from the core aspects behind data wrangling, to using the most popular tools and techniques. This book starts by showing you how to work with data structures using Python. Through examples and activities, you’ll understand why you should stay away from traditional methods of data cleaning used in other languages and take advantage of the specialized pre-built routines in Python. Later, you’ll learn how to use the same Python backend to extract and transform data from an array of sources, including the internet, large database vaults, and Excel financial tables. To help you prepare for more challenging scenarios, the book teaches you how to handle missing or incorrect data, and reformat it based on the requirements from your downstream analytics tool. By the end of this book, you will have developed a solid understanding of how to perform data wrangling with Python, and learned several techniques and best practices to extract, clean, transform, and format your data efficiently, from a diverse array of sources.

Preface

An Extension to Data Wrangling

This is the concluding chapter of this book; we want to give you a broad overview of some of the exciting technologies and frameworks that you may need to learn about beyond data wrangling to work as a full-stack data scientist. Data wrangling is an essential part of the whole data science and analytics pipeline, but it is not the whole enterprise. You have learned invaluable skills and techniques in this book, but it is always good to broaden your horizons and look beyond to see what other tools that are out there that can give you an edge in this competitive and ever-changing world.

Additional Skills Required to Become a Data Scientist

To practice as a fully qualified data scientist/analyst, you should have some basic skills in your repertoire, irrespective of the particular programming language you choose to focus on. These skills and know-how are language-agnostic and can be utilized with any framework that you have to embrace, depending on...
