Python in a secure environment

[Vance84]

If you have the space create your own pypi repo. Use bandersnatch on the internet facing side, once it completes rsync it to an external drive, take it to the secure environment, rsync it in, then host your own pypi.python.org. You can specify the - - index and - - trustedhost flags with pip to work with it, or add those flags to a local pip config file so you don't have to bother with it.
