Windows only: Using the msvcrt module:
from msvcrt import kbhit, getch
a, b = 1, 1
while True:
a, b = a+b, a
print a
if kbhit() and getch() in 'sS':
print "\nThanks!"
break
There is a portable getch recipe in the Python Cookbook:
<http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/134892> that
supposedly should work on Windows, Linux and Mac OSX too.
If you just want to break the loop, and don't care too much in which state
your variables remain, you can use Ctrl-C and catch the KeyboardInterrupt:
a, b = 1, 1
try:
while True:
a, b = a+b, a
print a
except KeyboardInterrupt:
print "\nThanks!"
... continue program ...
