Ok I was speaking quasi metaphorically
If you have some non-metaphors please tell!

Take the basic 'content':
x = 1
y = 2
z = 3

A. Occuring exactly as above at module level
B. Occuring exactly as above inside a function
C. Occuring thus
x = 1
foo(2,3)

def foo(y,z):
...

D. 
def foo():
  x = 1
  def bar():
     y, z = 2,3
...

E.
def foo():
  x = 1
  bar(2,3)
  ...

def bar(y,z):
  ...


In A,B,C,D,E at some point there's x,y,z having values (contents) 1,2,3
How do you distinguish them?

I call it the shape of the scope (or environment or bindings or namespace or
...???)

You have a better descriptor for the idea?
