- pygame module to work with touch input— get the number of touch devices — get the a touch device id for a given index — the number of active fingers for a given touch device — get information about an active finger New in pygame 2: This module requires SDL2. - pygame._sdl2.touch.get_num_devices()¶
- get the number of touch devicesget_num_devices() -> intReturn the number of available touch devices. 
 - pygame._sdl2.touch.get_device()¶
- get the a touch device id for a given indexget_device(index) -> touchid- Parameters:

- touchid (int) -- The touch device id. 
- index (int) -- The index of the finger to return information about, between 0 and the - number of active fingers.
 
 Return a dict for the finger indexactive ontouchid. The dict contains these keys:id the id of the finger (an integer). x the normalized x position of the finger, between 0 and 1. y the normalized y position of the finger, between 0 and 1. pressure the amount of pressure applied by the finger, between 0 and 1.
