This question is an extension of this:
[What identifier of operator must be entered for assign shortcuts](https://blender.stackexchange.com/questions/63430/what-identifier-of-operator-must-be-entered-for-assign-shortcuts/63449#63449)

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
