#38827 — Simulate Keyboard keypress Delay

I am using the windows api feature getasynckeystate() to check the status of every key pressed; like this;

#always checking
while(True):
    #iterate through list of ascii codes
    for num in range(0,127):
        #if ascii code key is being pressed
        if win32api.GetAsyncKeyState(num):
            #do stuff

This works great, almost. The issue that comes up now is that every time i press a key, the code grabs two or three key presses.

So i tried making sure that repeated keys weren't pressed repeatedly;

#always checking
while(True):
    #iterate through list of ascii codes
    for num in range(0,127):
        #if ascii code key is being pressed
        if win32api.GetAsyncKeyState(num):
            if oldkeychar == num:
                #don't do stuff
            else:
                #do stuff

this works great, but It won't record stuff like 'look' or 'suffer' because it doesn't record repeated keys. So I try doing a delay instead;

#always checking
while(True):
    #iterate through list of ascii codes
    for num in range(0,127):
        #if ascii code key is being pressed
        if win32api.GetAsyncKeyState(num):
            if oldkeychar == num:
                if crrenttime > (time.time() - .5)
                    #do stuff because key has been repeated, but not because it was held down
                else:
                    #don't do stuff because key is pressed to soon
            else:
                #do stuff because key is not repeated
                currenttime = time.time()

this almost works, but I end recording some double keypresses, and missing others. Does anybody have any suggestions?

work better? Grab all the keys at once into an array, then scan the
array for status...

	Off hand, the simplest scheme I could think of is, when you detect a
key press, you loop over it until you detect the key release -- only
then do you start scanning for other keys.

	IOWs, you should not be triggering on the state itself, but on the
change of state in both directions.

I believe you can use the raw_input function in python.

But loop through strings ended by \r\n or \r.

this will only work on a windows machine. It is from C++ runtime lib 
msvcrt.dll


in py module 
import msvcrt

while 1:
    ch = msvcrt.getch()   ## returns one char
    if ch == 'Y' :
       # do stuff or break
        break

    print "%d (%r)"  % (ch, ch)


  # also,  kbhit()  #  returns true if char is available

  # also, ungetch(ch)  # undo char ch
