While not exactly "the interactive interpreter", you can use pdb
to drop to a debugging prompt where you can "access the modules,
functions and variables the application can". The common idiom
is to insert a line like

import pdb; pdb.set_trace()

in your code to have a break-point stop execution at the
designated point and leave you at a prompt where you can explore.

-tkc

pdb is a debugger, and provides a lot more than you're looking for, I
presume.
You may want to look at the code [1] and cmd [2] modules too.

you can also use the -i switch to start the interactive interpreter once
the script reaches execution:
$ python -i myprogram.py
program output
