Learn Python by Building Data Science Applications

Summary

In this chapter, we covered the foundation of Python's data science stack—the NumPy, pandas, SciPy, scikit-learn, and Jupyter libraries. By doing so, we were able to gather an understanding of this ecosystem, why and when we need all of these packages, and how they relate to each other. Understanding their relationships helps to navigate and search for a specific functionality or tool to use.

We also touched upon the reasons why NumPy-based computations are so fast, and why this leads to a somewhat different philosophy of data-driven development. We further showcased how pandas complements NumPy arrays by supporting plenty of data formats and types, and SciPy and scikit-learn build upon those data structures, allowing us to quickly ...
