[Tutor] Stop a long loop in python console or in wxpython?

[xbmuncher]

I have this script:

import time

def hello():
    print "yay you got me to print"

def longLoop():
    x = 0
    for n in range(100000):
        time.sleep(5)
        x = x + n

longLoop()


It will run in the console for a long time. How can I send a command and
cause it to stop and pursue hello() function? I don't think this is possible
in the console.. and really I'd like to create a GUI that will run the
longLoop() function after I push a button and then press another button to
stop the longLoop() function and run the hello() function. How can I do this
in the wxPython, which is gui of choice for python. I'll settle for a way to
do it via console as well. The overall idea is, is that I want to cut short
the process of a piece of code in order to start another piece of code.

Can you help me with this?

Thanks.
