Hardly, since the "code segment" is byte compiled. It can be disassembled with
the "dis" module (see below), but there is no way to get the source code
(including variable names and comments), even though the translation process is
pretty straightforward.

The best way for your kind of interactive work is propably to choose an IDE,
which allows you to execute arbitrary regions of an editor window. The Emacs
pymode does, IDLE propably also.
