[Pythonmac-SIG] how to interrupt a running script in 1.6a2 ?

[David and Jessica Fashena]

Hello all,

I have just begun using Python and have a basic question.  I was running a
script (pi.py) in the Python 1.6a2/Demo/scripts folder to calculate Pi
forever.  Having seen a few thousand digits, I was unable to   halt the
program, and ultimately had to force a machine restart.   I tried a number
of different key combinations e.g. cntrl-c, cntrl-d, ESC, command- etc.

Is there a way to halt a running script?

thanks much,
