Sometimes I feel learning the basics of programming are more important than learning just bunch of code blocks from stackoverflow.

1:58 instance of a class 를 다룰 때는 object = instance. because python is a object-oriented programming language. 3:15 you yourself are an instance of the human class. Thank you

Yeah, that helped me understand too. The class is humans, and the instance would be a single specific human. Albert Einstein is an instance of humans.

sorry buddy but I personally found your explanation to be convoluted and unclear overall. You started giving vague examples and totally deviated from the initial question is what i felt after the video . I hope others understood the difference but I sure didn't. I totally appreciate your attitude to ask questions and probe deeper to find the clear answer , kudos to you inculcating such good behavior , I like this video but not your explanation. PS: her name is spelled - 'pre' 'yan' 'ka'

so, the "Instance of the Class" is "the copy of that Class" which you are going to use. And the "Object" is "the given name to that COPIED Class". and now, you can approach to that copied class(instance of class) through that given name which is called an "object"

Also, another thing I just learned while re-watching it: an instance is the definition of the object in the class (i.e. if smartphone was a class and iphone was the object, the name of the object [iphone] is the definition or instance.)

Can anyone explain if instancing does this? say 2 npcs are told by the same code that if they collide on a rock they should move left. Now this happens independently on the two depending if a collision happens. Is that what instancing does? it assigns the same code to happen independently on multiple npcs? I am making a game, but without this feature I will have to write tons of code for each of the dozens of npcs of the world each having different variables... that would be a pain!

when the object of the class is created is the object and when the object is passed into the class as argument at that time it becomes instance. is this understanding correct ? if not let me correct it...

I get it ...... so as far as an object is concerned , an object essentially is a products that are made by a class at a time .... right and these products which are created and taken at a perticular time when some methods ask for and hand overed is essentially an instance of a class which forms an object at a time May be i understood this way.

I think your examples are kinda vague not to mention how you conducted the video. So my suggestion: maybe next time you should kinda loosen up a little, not be so tense, and you should be also aware of your tone because some people given all these factors have different perceptions. Also, don't be so overzealous about someone saying sorry for asking you a question in the beginning, it appears as if you are a father lecturing his child, keep it simple and video friendly and don't be so hung up about an audience response. Any questions? Furtherore, since this video is about the difference between objects and classes I would show some code while presenting and just loosen up, you look like an angry man who has personal issues.
