How to execute/run a *.py file, win7, py3.2..?

[vmars316]

Greetings,
windows7, portablePython3.2:
What if i wanted to send myProg.py to a friend to RUN (who has python
installed).
Isn't there a way just to doubleClick on myProg.py, to get it into the
interpret/RUN?
Could i RUN a myProg.o ?
There must be a way to initiate the RUNning of a myProg.py without
IDLE or pyScript, or the like.
What if i wanted to write my own program in maybe "C",
who's job it is to initiate interpret/run any *.py program.
How does IDLE or pyScript do it?
And yes. i am interested in py2exe or the like, for windows7.
And would like to know what's available, like py2exe.

Thanks...vm
