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?
