ArcPy and ArcGIS - Second Edition

By: Silas Toms, Dara OBeirne

Overview of this book

ArcGIS allows for complex analyses of geographic information. The ArcPy module is used to script these ArcGIS analyses, providing a productive way to perform geo-analyses and automate map production. The second edition of the book focuses on new Python tools, such as the ArcGIS API for Python. Using Python, this book will guide you from basic Python scripting to advanced ArcPy script tools. This book starts off with setting up your Python environment for ArcGIS automation. Then you will learn how to output maps using ArcPy in MXD and update feature class in a geodatabase using arcpy and ArcGIS Online. Next, you will be introduced to ArcREST library followed by examples on querying, updating and manipulating ArcGIS Online feature services. Further, you will be enabling your scripts in the browser and directly interacting with ArcGIS Online using Jupyter notebook. Finally, you can learn ways to use of ArcPy to control ArcGIS Enterprise and explore topics on deployments, data quality assurances, data updates, version control, and editing safeguards. By the end of the book, you will be equipped with the knowledge required to create automated analysis with administration reducing the time-consuming nature of GIS.

String manipulation

There are three major methods for inserting variables into strings. Each has different advantages and disadvantages of a technical nature. It's good to know about all three, as they have uses beyond our needs here, so let's review them.

String manipulation method 1: string addition

String addition seems like an odd concept at first, as it would not seem possible to "add" strings together, unlike integers or floats which are numbers. However, within Python and other programming languages, this is a normal step. Using the plus sign "+", strings are "added" together to make longer strings, or to allow variables to be added into the middle of existing strings. Here are...
