Run an interactive PyShell from within Go4:

Thanks to TPython's interpreter state being preserved in between calls, 
closing/reopening PyShell allows to continue a session. Note that the 
analysis is paused for each command-line input, and opening a PyShell 
counts as one call.

Under Ubuntu, PyShell is part of the "python-wxtools" package:
sudo apt-get install python-wxtools
