The Astropy Project is a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python astronomy packages. In addition an ecosystem of Astropy affiliated packages is growing, some of which are planned for inclusion in the Astropy core when they are matured, some with specialised functionality will remain as separate repositories.

I will give an overview of the features and implementation of the Astropy package, focusing on parts that are more generally useful for scientists and engineers (e.g. astropy.units and astropy.modeling) and highlight recent developments in the core and affiliated packages.
