Overview of this book

The Pandas Workshop will teach you how to be more productive with data and generate real business insights to inform your decision-making. You will be guided through real-world data science problems and shown how to apply key techniques in the context of realistic examples and exercises. Engaging activities will then challenge you to apply your new skills in a way that prepares you for real data science projects. You’ll see how experienced data scientists tackle a wide range of problems using data analysis with pandas. Unlike other Python books, which focus on theory and spend too long on dry, technical explanations, this workshop is designed to quickly get you to write clean code and build your understanding through hands-on practice. As you work through this Python pandas book, you’ll tackle various real-world scenarios, such as using an air quality dataset to understand the pattern of nitrogen dioxide emissions in a city, as well as analyzing transportation data to improve bus transportation services. By the end of this data analytics book, you’ll have the knowledge, skills, and confidence you need to solve your own challenging data science problems with pandas.

Summary

In this chapter, you learned about the fundamentals of pandas data types and how to control them. After going through the range of data types in pandas, you learned how to inspect the underlying dtype of your data and how to convert it from one type into another. You also saw how converting your initial data into the appropriate dtypes can greatly reduce the memory usage of a DataFrame. Next, you learned about missing data, from how it's represented to its impact on dtypes. Then, you delved deeper into nullable and non-nullable dtypes and learned about the methods, functions, and operations that are specific to certain dtypes.

In the next chapter, you will learn about the different methods you can use to select data with pandas, be it with a DataFrame or a Series.
