Thank you for that. The distinction is important. ('==' vs 'is')
You also only showed it working on module globals. (For code at top-level, locals() returns the same as globals() )
You could also try it inside functions, where locals() really makes sense as a name. And you could try it in a nested function where there may very well be non-locals (eg. closure items) that aren't local or global.
But more interestingly, you could try it on items of a list, or members of a dictionary, where there's no name at all associated with the object.
