One way would be to have the html elements in a <form> element with a submit-Tag which has the address of the pyboard in it. Whenever you submit the form the values of the variables will be submitted with it, either in the url (method=get) or in the body (method=post) of the request.
A little bit more complicated would be a Javascript xmlhttprequest. This can be totally asynchronous and the data format can be more changed by you, for example JSON.

Take a look at "microdot" which is a web server for MicroPython. It includes an example that has a web page that lets you control a GPIO pin.

urequests is for sending HTTP requests, so that won't help here.
Did you take a look at microdot? It takes care of this for you. Let us know if we can help you get that set up.

i see microdot , but i think that it's going to overload the ram on my esp12 , because my prog is already substantial
for 2 variable there is no other less cumbersome solution ?
thank
