Given Turing-completeness, one should more precisely ask whether there
is already a library for doing something in Python rather than whether
something is possible with Python.

It is generally customary to wait /at least/ one day before pinging on
one's question again.

If you were to have searched PyPI (http://pypi....), you would
have found psutil, which seems to fit your bill:

Turing-completeness is irrelevant to questions like getting memory and
CPU info for a process. These are not issues of computability...

True, but given that it is possible to access most *nix APIs from
Python and win32all provides what I understand to be extensive access
to the Win32 API from Python, cross-platform coding is almost always
possible in Python. You might have to manually deal with each case
yourself though. (More technically, I suppose that's being
multi-platform with relatively easy DIY cross-platform).

Cheers,
Chris
