First of all thanks for the excellent and detailed explanation Steven.
As for namespace:
a = 5
1. a is associated to some memory location
2. the latter holds value 5
So 'a', is a reference to that memory location, so its more like a name
to that memory location, yes? Instead of accessing a memory address with
a use of an integer like "14858485995" we use 'a' instead.
So is it safe to say that in Python a == &a ? (& stands for memory address)
is the above correct?
I say this because here you said that: Instead, there is a namespace,
which is anassociation between some name and some value:
When you say that you mean that a is associated to some value as in
memory location or to that memory location's address?
