APPENDIX B

INTRODUCTION TO PANDAS

This appendix introduces you to Pandas and provides code samples that illustrate some of its useful features. If you are familiar with these topics, skim through the material and peruse the code samples, just in case they contain information that is new to you.

The first part of this appendix contains a brief introduction to Pandas. This section contains code samples that illustrate some features of data frames and a brief discussion of series, which are two of the main features of Pandas.

The second part of this appendix discusses various types of data frames that you can create, such as numeric and Boolean data frames. In addition, we discuss examples of creating data frames with NumPy functions and random numbers.

Note: several code samples in this appendix reference the NumPy library for working with arrays and generating random numbers, which you can learn from online articles.
