Well, no. First-level names, yes, but each object itself is a namespace, so every name will be bound to an object that can contain names. To use my favorite example:

def f(): pass f.permissions = 'author'

Except that those are not names, they are attributes. Namespaces nest, in Python; permissions does not live in namespace, which becomes obvious if you try to nest it

def f(): return permissions

f.permissions = 'author' print f()

Traceback (most recent call last): File "a.py", line 5, in ? print f() File "a.py", line 2, in f return permissions NameError: global name 'permissions' is not defined
