Quotes About Namespace

in active directory domain lingo, a group of computers that shares a single namespace and DNS structure is called a domain. a group of domains linked in parent-child relationships (also like the roots of a tree) is called a tree.

Window is the global object. It may seem a little weird, but the window object acts as your global environment, so the names of any properties or methods from window are resolved even if you don't prepend them with window. In addition, any global variables you define are also put into the window namespace, so you can reference them as window.myvariable.

Every time you use an expression of the form object.attr where object is an instance or class object, Python searches the namespace tree from bottom to top, beginning with object, looking for the first attr it can find.
