numpy and matplotlib are the leaders here.

Certainly. In your position I think the easiest option is to have
Python installed on all your machines and simply copy your programs aka
scripts from machine to machine. I suppose it all depends on how easy
it is to bribe your admin people!!!

No "usually" about it :)

http://ipython.org/notebook.html could be what you're looking for here,
both for your collaboration rather than comparing notes by email, and
for actually producing your output.

Anaconda always comes up in this area, with numpy, ipython and
matplotlib included in the distibution, see

No, they'll work perfectly happily side by side.
If you're not already aware then scipy http://www.scipy.org/ should be
pointed out, as well as pypi https://pypi.python.org/pypi which
currently holds 64383 packages. Heck, I almost forgot pythonlibs
http://www.lfd.uci.edu/~gohlke/pythonlibs/ which is a godsend if you
haven't got Visual Studio and don't want to install it.

My fellow Pythonistas, ask not what our language can do for you, ask
