Two approaches are feasible here.  Best would be to change your
library code (usually in minor ways) so that it just works on both
version 2.7 and 3.x  That would mainly involve including from __future__
imports inside a conditional clause - based on version check.  Many of
the most painful differences have been back ported to 2.7

If that's just not doable, then write the code such that either 2to3 or
3to2 will convert your master copy to the other state.  If you can avoid
separately editing the two versions, bug will be lots easier to contain.
    (see  https://wiki.python.org/moin/3to2   but I haven't ever used
it)

First, I haven't seen any mention of a source control system.  Get one,
learn it, and use it.  That should always hold your master copy.  And
the actual repository should be on a system you can access from any of
the others.

Then, once you can get to such a repository, you use it to sync your
various local copies on your individual machines.  You could have the
synch happen automatically once a day, or whatever.  You could also
build an auto-synch utility which pushed the synch from the server
whenever the server was updated.

If you're always going to be using these machines with real-time access
to the central server, you could use Windows shares to avoid needing any
updates.  Just create a share on the server, and mount it on each of the
clients.  Add it to your system.path and you're done.

I don't like that last answer because I'm frequently *don't* have access
even to the internet, never mind to a particular server.
