python -i (interactive environment)

[Joe]

Thanks Michael, that's what I was looking for.

Are there any differences between that and the actual interactve prompt that 
I should be aware of?

Would you consider that a better method than using (thanks to those who 
suggested this other option):

import os
os.environ['PYTHONINSPECT'] = '1'
