I have found a solution:

def clear_keyboard_buffer():
  try:
    while msvcrt.kbhit(): msvcrt.getwch()
  except:
    fd = sys.stdin.fileno()
    fcntl_flags = fcntl.fcntl(fd,fcntl.F_GETFL)
    fcntl.fcntl(fd,fcntl.F_SETFL,fcntl_flags|os.O_NONBLOCK)
    try:
      while sys.stdin.read(1): pass
    except:
      pass
    fcntl.fcntl(fd,fcntl.F_SETFL,fcntl_flags)
