ALCF Discontinues Support for Python 2

The Python development group has discontinued support for Python 2 as of January 1, 2020, and the ALCF has followed suit. Currently installed Python 2 modules will continue to be available, but in a strictly unsupported capacity. Users are advised to port their code to Python 3 to ensure future compatibility with ALCF software. Official documentation for transitioning from Python 2 to Python 3 can be found at https://docs.python.org/3/howto/pyporting.html. Users are also advised to follow the recommendations at https://www.python.org/dev/peps/pep-0394/ and to explicitly call the version of Python required by their script.
