Also, the attribute name used by the class to hold a descriptor takes
prece- dence over attributes stored on instances.

Python does not have ‘object’ as a keyword. ‘and’ is a keyword.

random.rand returns a list. x is a label to this list (container).
y=x creates another label to the same container/list.

I can testify, as the person who started this thread, that there is no
fear or suspicion of lambda here. I use it
I believe the namespace object you are referring to is exactly a class.
IIRC, classes came about as a "module in a module".
Regardless, all use cases you've listed are already satisfied by use of the
static and class method decorators. Methods decorated with these do not

Could you please tell me how to compare both id by using equal operator.
