The Astropy Project is a community effort to develop a core package for astronomy using the Python programming language and improve usability, interoperability, and collaboration between astronomy Python packages. The core astropy package contains functionality aimed at professional astronomers and astrophysicists, but may be useful to anyone developing astronomy software. The Astropy Project also includes "affiliated packages," Python packages that are not necessarily developed by the core development team, but share the goals of Astropy, and often build from the core package's code and infrastructure.
Aside from the actual code, Astropy is also a community of astronomy-associated users and developers that agree that sharing utilities is healthy for the community and the science it produces. This community is of course central to accomplishing anything with the code itself. We welcome anyone who wishes to contribute to the project and expect everyone in our community to follow the code of conduct when interacting with others.
