Summary

In this chapter, we discussed about the Zen of Python and covered the basics of programming using Python. We began our exploration of ArcPy and how it can be integrated with other Python modules to produce complete workflows. We also discussed the Python standard library and the basic data types of Python.

Next, we will discuss how to configure Python for use with ArcGIS, and explore how to use Integrated Development Environments (IDEs) to write scripts.
