mimic -i from script

[John Hunter]

Is it possible at the end of a script to issue some python command
that will cause the python shell to open as if the -i flag had been
used


Eg, 

  > python -i somefile.py 

and 

  > python somefile.py 

will both behave the same if somefile.py ends with the right magic
incantation?

Thanks,
John Hunter
