Here are some general websites and tutorials for learning how to code in a variety of languages:
- Lessons from Data Carpentry . Free open source lessons for R, Python, SQL. Applied programming options based on field of study.
- Data Camp. Paid service but excellent and expansive content. A worthwhile investment if you need to learn a language. R, Python, SQL, and more.
- Software Carpentry lessons for open source content development in Shell, Git, Python, and R. Content is designed to be instructed, but individuals can move through content in a self-paced format.
Python is an open-source development language used widely for data science and used heavily in geospatial science. It’s fairly easy to learn, is integrated to the ArcGIS world, and has dozens of available libraries for spatial data management, analysis, and visualization.
There is no shortage of Python resources online, but here are few to get you started:
