Now updated for Windows 10!
To access the Python interpreter and run Python scripts you need to know the location of python.exe for the installation you wish to use. To make running scripts easier you may wish to add this location to your system Path, either temporarily or permanently. This post describes how to do each of these as well as some general considerations.
As a researcher I often develop for Python, JavaScript (both Node.js and browser) and HTML/CSS on Windows. This series of blog posts describes my development environment from high level technologies down to the specific apps I use every day. It should be of interest to anyone doing Python or web development – hopefully you pick up some new ideas, useful apps or different ways of doing things!
Installing GDAL/OGR for Python on Windows is now even easier!
For some reason it is insanely difficult to use Spatialite from Python on Windows. In theory the following should create and connect to an in-memory database, then load the Spatialite extension (after mod_spatialite and friends have been put somewhere and added to your system Path):

conn.enable_load_extension(True)
conn.execute("SELECT load_extension('mod_spatialite')")
However, this fails stating: OperationalError: The specified module could not be found.
I have recently been working with CherryPy. Although it seems very powerful, it is quite hard to find simple and clear online examples for some things. In this case I wanted to set up a RESTful server that can accept POST requests containing JSON/GeoJSON, and return JSON/GeoJSON.

ArcGIS installs its own version of Python that is not officially registered with the system but can in reality be used just like a normal install. I personally prefer just to use this as my primary Python, but it is not always possible. The instructions below can help you let a different Python install access and use Arcpy Continue reading
The following post builds upon the script and methods developed in Part 1 and Part 2, so read them first!
The purpose of this series is not to give you a one line example that you can copy and paste to your code, but step through the process and make the underlying principles clear. Continue reading
