Namespaces

Class Namespaces provides a small collection of types. Neither type has public methods of interest; they are used solely in the context of Python’s own protocols.

NamespaceableMeta

class class_namespaces.NamespaceableMeta

Metaclass for classes that can contain namespaces.

A note for people extending the functionality: The base class for NamespaceableMeta uses a non-standard super() invocation in its definitions of several methods. This was the only way I could find to mitigate some bugs I encountered with a standard invocation. If you override any of methods defined on built-in types, I recommend this form for maximal reusability:

super(class, type(self)).__method__(self, …)

Namespaceable

class class_namespaces.Namespaceable

Optional convenience class. Inherit from it to get the metaclass.

Namespace

class class_namespaces.Namespace(*args, **kwargs)

Namespace.

Namespace() -> new empty namespace Namespace(mapping) -> new namespace initialized from a mapping object’s

(key, value) pairs

Namespace(iterable) -> new namespace initialized as if via:

d = {} for k, v in iterable:

d[k] = v

ns = Namespace(d)

Namespace(**kwargs) -> new namespace initialized with the name=value pairs

in the keyword argument list. For example: Namespace(one=1, two=2)

Namespaces implement the context manager protocol. When the context is entered in an appropriate class creation scope, the Namespace shadows the currently visible scope.

Namespaces can be re-entered after they are exited, provided they’re in the same parent scope.
