Python 3.8.0a2 is the second of four planned alpha releases of Python 3.8, the next feature release of Python.  During the alpha phase, Python 3.8 remains under heavy development: additional features will be added and existing features may be modified or deleted.  Please keep in mind that this is a preview release and its use is not recommended for production environments.  The next preview release, Python 3.8.0a3, is planned for 2019-03-25.

Thanks to all of the many volunteers who help make Python development and these releases possible!  Please consider supporting our efforts by volunteering yourself or through organization contributions to the Python Software Foundation.
