How to REPL?

[François Pinard]

Hi, people.

I vaguely remember this has been discussed, a long while ago, but do not
handily find the discussion in my archives.

Would someone happen to have a modest recipe for a read-eval-print-loop,
that could be used to trigger interactive Python from within an otherwise
batch script?  I would like read-write access to the Python environment,
if possible.  Thanks for your reply, in advance.

If it matters, on _this_ machine, I'm using 1.5.2.
