Hi ,
Does anyone use Python for developping applications that work with a touch screen?

Yes.

You should probably specify the platform and the type of applications
that you're interested in.

Mobiles (Android, iOS, Sailfish OS)? Windows 10 Tablets? Ubuntu Touch?
Embedded systems?

You should take a look at Kivy: https://kivy.org/

I've done it on a system where the touch screen events were treated the
same way as mouse events. Coding works out about the same way.

I was thinking about Python touch screen applications for industrial boards( computers).
If I have a touch screen with that industrial board, what I must have installed to be able to
write touch screen applications in Python?

This could be any platform: QNX, Android, Windows, Embedded Windows,
Windows CE, Windows Mobile, Linux with X, Linux with Wayland, Linux
command line and a display connected via SPI or whatever...
If you don't write which platform you actually have, you will probably
not get answers that will help you.

If you go with Kivy (its built for multitouch graphical interactive
applications, can work on Windows, Linux, MacOSX, Android), see the
following page for requirements:

https://kivy.org/docs/installation/installation.html

And learning how to use it (see examples).

https://kivy.org/docs/examples/gallery.html

Really, give it a try, even on your mouse controlled interface.

Laurent.

I would like to learn more how to write python based touch application
for embedded system but I do not know what conditions a touch screen must have so that it
will response to touch.
Does anyone know?

These days GUI toolkits such as GTK+ or Qt provide convenient methods
for interacting with touch displays including touch, dragging, gestures
(pinch to zoom), multi-touch, etc.

In its simplest form GUIs on touch screens are identical to GUIs with a
mouse. Normal button widgets work great with fingers for example. Even
slider adjusters work pretty much the same with a finger and with the
mouse.

More complicated things like pinch to zoom and multi-touch require a bit
more help from the toolkit.

As Deitmar said, you will have to get a lot more specific in your questions.
