I was going through this topic again and asking chatGPT for clarifications.
GPT: No, I wouldn’t say that turning a class into an object is the opposite of the type() function in Python.

In Python, a class is a type, and when you create an instance of that class, you are creating an object of that type. So, in a sense, a class can be seen as a blueprint for creating objects of that type.

The type() function in Python can be used to determine the type of an object or a class. When called with a class as an argument, type() returns the type of that class, which is type. When called with an object as an argument, type() returns the type of that object, which is the class it was instantiated from.

So, in summary, turning a class into an object is not the opposite of the type() function. Rather, a class is a type, and the type() function can be used to determine the type of a class or an object.

Me: would you say then that the following statement is inaccurate: Instantiation takes a class and turns it into an object, the type() function does the opposite of that. When called with an object, it returns the class that the object is an instance of.

GPT: Yes, I would say that the statement “Instantiation takes a class and turns it into an object, the type() function does the opposite of that. When called with an object, it returns the class that the object is an instance of” is inaccurate.

Instantiation does not turn a class into an object. Rather, it creates a new instance of the class, which is an object of that class. The class itself is not transformed into an object, but rather serves as a blueprint or template for creating new objects.

Similarly, the type() function does not do the opposite of instantiation. When called with an object, it returns the type of that object, which is the class that the object was instantiated from. It does not transform the object back into a class or blueprint.

So, to summarize: instantiation creates an object from a class, and the type() function returns the class of an object, but neither of these operations transforms one into the other.
