I have stuck a bit with this example(took this one from the book).
Here are a description steps of what I've done till now:
Step 1 - creating an empty namespace:
class rec: pass
IMHO that is not actually creating a namespace; it is just
declaring/defining an empty class.
I pythonland, a namespace is a many to one mapping between names and
objects. They are usually but not necessarily implemented with dicts.
Some might restrict the term to a mapping with a .attribute interface
for getting and setting. Others consider any string-key dict to be a
namespace. The types module has a class SimpleNamespace. It has been
proposed to move it to builtins with the name 'namespace'.
BTW, the recommended Python 3.x way is
class Rec (object):
pass
I hope you meant Python *2*.x, where '(object)' *is* needed to make a
newstyle class. In 3.x, '(object)' is optional and normally omitted
except in code meant to run unchanged in 2 and 3.
