This chapter was a brief introduction to this book. You learned how to set up a Python environment in Wakari.io to be able to run the code samples provided throughout the text. This included instructions on how to update the default Wakari.io Python environment to support the required packages that are required for all of the examples in the remainder of the text.

In the next chapter, we will dive into using pandas and its core data structures, Series and DataFrame. These will be core to representing data in later chapters, where we primarily use pandas DataFrame objects to represent financial data, which we apply to various financial analyses.
