Assigning HotKeys Using Python Commands This question is an extension of this:
What identifier of operator must be entered for assign shortcuts

I did not understand how have copied Python command or Data Path
 available I could to determine that it is the context is wm.context_toggle
and attribute is space_data.use_occlude_geometry.

Could someone explain in more detail the thing about where the operators came from?

I found on the official website section initiated to the python, but I can not be guided in it
Since i don't want to add another comment:

You can list all available operators via Info Menu -&gt; Help -&gt; Operator Cheat Sheet and look at the Text Block generated in the Text Editor

The operators are listed by category in this section (at the bottom of the page) of the API documentation.

If you drag down the Info Area you can see a history of recently used (registered) operators

You can hover over buttons with python tooltips enabled.

The context data is listed in this section (available members depend on the area/mode)

The different spaces used by the corresponding editors/areas are listed in this section (subclasses - top of the page)
