PyPy, the Python implementation that uses an optimizing compiler for speed, has been awarded $200,000 as part of Mozilla’s Open Source Support initiative.
According to a blog post from the PyPy team, the money will go toward funding Python 3.5 support in PyPy.
PyPy supports Python 3 through a separate version of the interpreter, similar to how the default Python 3 and Python 2 implementations are developed independently.
