Penn state has a nice collection of ArcGIS & Python
programming step by step guide for their
GEOG 485 students, which is also available for non-students via Penn state
website. This course’s is main aim is to
make student able to use the Python scripting
language to automate GIS tasks in ArcMap, assemble ArcView geoprocessing
tools into models to solve GIS problems, and run the tools from scripts to
automate GIS tasks.
Although no
previous programming experience is assumed, the course's target is to make a student as a GIS programmer/analyst in ArcGIS and Python environment.
The course is basically
divided into four parts:
Part 1: Introductionto GIS modeling and Python
You will learn fundamentals of python.
Part 2: Python and programming basics
You will dive into
Python fundamentals and will get a better understanding of the
Python concepts as they are explained and demonstrated from several
different perspectives.
Part 3: GIS data access and manipulation with Python
You will learn
the ways to read and write GIS data using Python. How you can create and open
datasets within a script? How you can read and write data using both
geoprocessing tools and cursor objects? It also has few steps by step guide to
manipulate rasters with Python.
Part 4:Practical Python for the GIS analyst
“You'll learn now to modularize a section of code to make it usable in multiple places. You'll learn how to use new Python modules, such as os, to open and read files; then you'll transfer the information in those files into geographic datasets that can be read by ArcGIS. Finally, you'll learn how to use your operating system to automatically run Python scripts at any time of day".
