Returns a character string if a key is pressed during the call of Inkey(). It doesn't interrupt (halt) the program flow.

If special keys (non-ASCII) have to be handled, RawKey() should be called after Inkey().

k$ = Inkey()

​I use python for some little things here too Never having tried this in python, so I had to look this up​ not sure where that code which you found came from I just looked on the python org website And there appears to be a "getkey" library https://pypi.python.org/pypi/getkey/0.6.5 eg. from getkey import getkey, keys key = getkey() if key == keys.UP: ... # Handle the UP key elif key == keys.DOWN: ... # Handle the DOWN key else: # Handle other text characters buffer += key print(buffer)
