Basically, it just says (to me at least): "I intend to use these name within this block, but don't care about them elsewhere." It's sort of an informal scope without actual scoping rules. But of course, this is just existing Python, and anyone who wants to or doesn't is free to use or not use that style. In truth, I've thought about doing it from time to time, but never actually bothered in production code, just as a toy. -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons.
