I also recommend learning how to request help files within the interpreter and list available methods, functionality and modules, rather than consulting the external help files. It´s not necessary to know the language from a to z to use it within a GIS – with some basic knowledge you can get up to speed pretty fast and use it within ArcGIS. If you´re new to programming, this can be a little overwhelming at first as Python has a lot of built-in functionalities. In order to be able to use Python within a GIS, you need to learn about Python syntax, data types, commands, built-in functionalities, loops and the like. So, to begin with, I’d recommend learning the basics of Python –I´ll get to the GIS part later.
One: First things first – learning the basics This guide focuses on Python scripting as Python programming is more complex and takes more time to learn – for now, we´re good with learning Python scripting. In ArcGIS, Python scripting can be used for automating tasks (through running Python scripts), as well as writing applications, such as add-ins.
Python is a good choice to start for learning GIS programming, as it can be used as a scripting and programming language. From a beginner’s perspective, it´s not recommended to start learning as many languages right away, but instead to start easy and differentiate later on, depending on your needs. GIS programming in my opinion starts with Python, but certainly won´t end there. That´s why I put together this guide to get you started with Python programming for GIS. This is easier said than done: the possibilities can be overwhelming, especially if you don´t know where to begin. As a GIS analyst, you can raise your market value by learning to program.
