Instances of this namespace can store arbitrary attributes, which are stored in the instances dictionary. They are then available via attribute lookup, e.g. ns.attr, and index lookup, e.g. ns['attr']. The Namespaces support acquisition. To link the object to another object, set self.baseobj to the other object. Attributes not found in the Namespace instance are then looked up in the other object as well. NOTE: All methods and internal attributes must start with an underscore. Namespace attributes must *not* start with an underscore to prevent naming collisions with internal variables and methods. Note that names with leading underscore cannot be acquired. c K s | o | i i | ƒ n d S( sV Initializes the namespace with the attributes given as keywords.

The attributes named in save are not cleared. Per default all attributes are cleared. You may want to save the baseobj attribute in case you use it. Class variables are not cleared this way, but overriding instance variables do get deleted. If recursive is true (default is false), the namespace is cleared recursively, meaning that all Namespace instances contained in it are also cleared.
