Accessor Method: This method is used to access the state of the object i.e, the data hidden in the object can be accessed from this method. However, this method cannot change the state of the object, it can only access the data hidden. We can name these methods with the word get.
A function like Turtle or Point that creates a new object instance is called a constructor, and every class automatically provides a constructor function which is named the same as the class.
Instantiation: The new keyword is a Java operator that creates the object. As discussed below, this is also known as instantiating a class.
The __set__() method is invoked when the value is set to the attribute, and unlike the __get__() method, it returns nothing. It has two arguments apart from the descriptor object itself, i.e., the instance which is the same as the __get__() method and the value argument, which is the value you assign to the attribute.
When investigating for another question, I found the following:
>>> class A:
... def m(self): return 42
...
>>> a = A()
This was expected:
>>> A.m == A.m
True
>>> a.m == a.m
True
But this I did not expect:
>>> a.m is a.m
False
And especially not this:
>>> A.m is A.m
False
Python seems to create new objects for each method access. Why am I seeing this behavior? I.e. what is the reason why it can't reuse one object per class and one per instance?
