What is a dot operator in Python? And how powerful is it!?


Question


What is a dot operator in Python? And how powerful is it!?

 

well - if we say that almost everything in Python is an object. And furthermore - every object has certain attributes and methods.

 

In python - the typical connection between the attributes or the methods with the object is let us say named or we  an also say indicated _with_ - or let us say _by_ a “dot” (”.”) written between the attributes or the methods and the object. Let us illustrate this formal behavior in python with a little example; if we look at lessie the dog. This dog - we can say does alot of things:

 

during the whole live of a typical dog  we ca admit that - he runs, walks, bites, sleeps and lots of other thigns more.
Here’s how we can spell out the above mentioend behaviour in a so called object-oriented style - well we might write this:

Lessie = Dog()
Lessie.walks()
Lessie.wows()
Lessie.runs()
Lessie.bites()
Lessie.eats()

and so forth and so forth and so forth and so forth

 

Well besides the above mentioened things - we can say that Lessie has additionaly and furthermore lets say different attributes and different qualities.


the question is: can objects have even more objects that belong to them,


Lessie.head.hair()
Lessie.head.hair.color = "browm";
Lessie.head.mouth.theeth.length.()


quesiton: can objects have even other objects that also do belong to them - in other words - do they are able to have a connection to the object with their own methods or attributes:

You can chain methods by returning an instance of self on a method call. You cannot chain objects as the dot operator is not an accessor for dictionaries. There are ways to hack an implementation of it, if you were so inclined, but I'd argue it'd be better to utilise the built-in native accessor syntax. There are many reasons to perform method chaining, mostly around quality of life for developers using your library. Not many reasons to use object chaining with the dot accessor other than you like how it looks.

    • VR is dead on the PS at this rate, sales just aren't there. Way more VR push on the PC, even Sony knows this and that's why they added PC support to the PSVR.
    • Borderlands series, Rematch, Broken Arrow, and more get Nvidia GeForce NOW support by Pulasthi Ariyasinghe Another Nvidia GeForce NOW games update has arrived, meaning subscribers now have even more games to jump into via the cloud if they own a copy. The latest wave touts 13 more games, and that includes the Borderlands franchise from Gearbox, Remedy's brand-new cooperative shooter FBC: Firebreak, and more. With the fourth entry now on the way, for those who have yet to jump into Gearbox's wacky looter shooter universe, Borderlands, Borderlands 2, Borderlands 3, and even Borderlands: The Pre-Sequel are now a part of GeForce NOW. The Sifu developer's rule-less soccer experience, Rematch, has also been released to standard edition owners today. With the latest update, for owners of the game or PC Game Pass subscribers, it is also accessible via the cloud on GeForce NOW. Here are the games announced for the program this week: REMATCH (New release on Steam, Xbox, available on PC Game Pass, June 16) Broken Arrow (New release on Steam, June 19) Crime Simulator (New release on Steam, June 17) Date Everything! (New release on Steam, June 17) FBC: Firebreak (New release on Steam, Xbox, available on PC Game Pass, June 17) Lost in Random: The Eternal Die (New release on Steam, Xbox, available on PC Game Pass, June 17) Architect Life: A House Design Simulator (New release on Steam, June 19) Borderlands Game of the Year Enhanced (Steam) Borderlands 2 (Steam, Epic Games Store) Borderlands 3 (Steam, Epic Games Store) Borderlands: The Pre-Sequel (Steam, Epic Games Store) METAL EDEN Demo (Steam) Torque Drift 2 (Epic Games Store) As always though, keep in mind that unlike subscription services like Game Pass, a copy of a game must be owned by the GeForce NOW member (or at least have a license via PC Game Pass) to start playing via Nvidia's cloud servers.
    • WHAT? First of all, Azure, literally, runs on THE LINUX KERNEL. I know, right? Windows is easier to develop drivers? This must be the joke of the century! Developing drivers on Linux, you can interact with low level implementation straight to the core. You can build and test them with standard tools like GCC and Make, no need for a full blown IDE or SDKs, only a kernel header and a Makefile. You can load/unload drivers dynamically, without rebooting, which makes debugging MUCH easier. You don't need to sign drivers, unlike Windows, even for local testing. And a ton of other conveniences. "There is no way a Linux distribution can compete against Windows". Literally, SteamOS competes against Windows on handhelds, playing games WRITTEN for Windows, BETTER than Windows. "DirectX is the most powerful API"? Really? Vulkan provides more low level control, less overhead, scales better with more threads, it's cross platform and extensible. How, exactly, is "DirectX the most powerful API"?
    • It's easier for the console market to pull in more revenue when they're prices are higher compared to the PC where games often come out cheaper than their console versions or go on sale quicker. Having said that, I'm not going to be paying $70 or $80 for a game, regardless of the platform it's on. Revenue aside, because raising prices on consoles skew things when the prices on the PC often stay around the same levels, it's been shown that the PC market is growing while the console market is overall flat. PC will pass consoles soon dropping them into 3rd place. And the PS5 being on track to pass the PS4 doesn't say much, if the console market was actually still growing Sony would've passed the PS2 as it's best selling console with the PS3, and the PS4 would've outsold both and so on. That's not happening. It took Nintendo to release a totally different hybrid system with the Switch to inject some new life into the "console" market. Even then it's pushed as a handheld first and the majority who buy it do so because it's portable and at a good price.
    • As with the rest of the misleading statement you made about SteamOS "limitations", you are wrong again. No, the XBOX does NOT run "slimmed down and modified Windows". It runs a HEAVILY modified version of the Hyper-V hypervisor, called "Nanovisor" and 2 VM partitions. One for games, one for the apps. It is NOT Windows, it can NOT run Windows games and its DirectX components are NOT the same as for Windows, they are customized for XBOX.
