So I will run into trouble if I install something here to make something else work, and then take it to the company where it does not work. So, to maintain the highest level of compatibility to the machines at work, I don't install extra packages.

I suppose getting them to install Python 2 is out of the question? It is

Well there is always going to be versioning. If you mean the
incompatibility split, then for 2/3 that is not going away. There will
be a Python 4, but the core developers have said they learned their
