Overview of this book

You already know you want to learn data science, and a smarter way to learn data science is to learn by doing. The Data Science Workshop focuses on building up your practical skills so that you can understand how to develop simple machine learning models in Python or even build an advanced model for detecting potential bank frauds with effective modern data science. You'll learn from real examples that lead to real results. Throughout The Data Science Workshop, you'll take an engaging step-by-step approach to understanding data science. You won't have to sit through any unnecessary theory. If you're short on time you can jump into a single exercise each day or spend an entire weekend training a model using sci-kit learn. It's your choice. Learning on your terms, you'll build up and reinforce key skills in a way that feels rewarding. Every physical print copy of The Data Science Workshop unlocks access to the interactive edition. With videos detailing all exercises and activities, you'll always have a guided solution. You can also benchmark yourself against assessments, track progress, and receive content updates. You'll even earn a secure credential that you can share and verify online upon completion. It's a premium learning experience that's included with your printed copy. To redeem, follow the instructions located at the start of your data science book. Fast-paced and direct, The Data Science Workshop is the ideal companion for data science beginners. You'll learn about machine learning algorithms like a data scientist, learning along the way. This process means that you'll find that your new skills stick, embedded as best practice. A solid foundation for the years ahead.

Data-Driven Feature Engineering

The previous section dealt with business-driven feature engineering. In addition to features we can derive from the business perspective, it would also be imperative to transform data through feature engineering from the perspective of data structures. We will look into different methods of identifying data structures and take a peek into some data transformation techniques.

A Quick Peek at Data Types and a Descriptive Summary

Looking at the data types such as categorical or numeric and then deriving summary statistics is a good way to take a quick peek into data before you do some of the downstream feature engineering steps. Let's take a look at an example from our dataset:

# Looking at Data types
print(bankData.dtypes)
# Looking at descriptive statistics
print(bankData.describe())

You should get the following output:
