Where can I find more python extension examples ?

edited June 24 in GX Developer
I am creating an extension using python. I am using the documentation
 and api reference:

But I haven't found a place where I can see more comprehensive examples. Are there such examples?

Specifically, I want to (among others) create a dialog with multiple inputs, which should be a common task. I don't see how it is possible to adopt gxproj.get_user_input for this. The lower level API also doesn't give me direction.
