Python don't do anything until keystroke -

so need python program or module executes main program once specific key pressed, example f10 key. other modules found (for example getch) executes once any key pressed.

since mention msvcrt, i'll assume (windows). you'd different in linux.

f10 2-byte return, 00 68, so... first byte 00, second byte 68. there 2-byte return has 224 first byte, you'll want check that, too.

i included block on kbhit() because if let block on getch() instead, pick ctrl-c , won't able break out. blocking on gives opportunity.

you can make little more generic if you'd like, hardcoded f10.

import msvcrt  while true:     if msvcrt.kbhit():         first = ord(msvcrt.getch())              if first in (0, 224):             second = ord(msvcrt.getch())             if first == 0 , second == 68:                 break
