Python 3 Rewrite

[cpressland]

Python 2 is EoL soon. Pls rewrite to the 3's.

I don't think that is the right approach. Python 3 is already over 10 years old, this is really not fitting for mangodb, which is on the top edge of technological development. Rather I'd say go directly with Python 4.

Why not Python 6 at least?
