Astropy Tutorials: Learn how to do common astro tasks with astropy and Python by Adrian Price-Whelan.
From the post:
Astropy is a community-developed Python package intended to provide much of the core functionality and common tools needed for astronomy and astrophysics research (c.f., IRAF, idlastro). In order to provide demonstrations of the package and subpackage features and how they interact, we are announcing Astropy tutorials. These tutorials are aimed to be accessible by folks with little-to-no python experience and we hope they will be useful exercises for those just getting started with programming, Python, and/or the Astropy package. (The tutorials complement the Astropy documentation, which provides more detailed and complete information about the contents of the package along with short examples of code usage.)
The Astropy tutorials work through software tasks common in astronomical data manipulation and analysis. For example, the “Read and plot catalog information from a text file” tutorial demonstrates using astropy.io.ascii for reading and writing ASCII data, astropy.coordinates and astropy.units for converting RA (as a sexagesimal angle) to decimal degrees, and then uses matplotlib for making a color-magnitude diagram an all-sky projection of the source positions.
The more data processing you do in any domain, the better your data processing skills overall.
If you already know Python, take this opportunity to learn some astronomy.
If you already like astronomy, take this opportunity to learn some Python and data processing.
Either way, you can’t lose!
Enjoy!
