Examples of namespaces are: the set of built-in names (containing > functions such as abs()<http://docs.python.org/2/library/functions.html#abs>, > and built-in exception names); the global names in a module; and the local > names in a function invocation. In a sense the set of attributes of an > object also form a namespace. The important thing to know about namespaces > is that there is absolutely no relation between names in different > namespaces; for instance, two different modules may both define a function > maximize without confusion — users of the modules must prefix it with the > module name. > The above paragraph was extracted from the description about namespaces from the Python tutorial(Python Scopes and Namespaces<http://docs.python.org/2/tutorial/classes.html#python-scopes-and-namespaces>).I do not understand what is meant by "A *namespace* is a mapping from names to objects". How I understand to be a namespace is a particular space within which a particular name is unique.For a example within the space set of built-in names the name "abs()" is used to denote the function which returns the absolute value of a number and no other function(operation) can be named abs() as a built-in function.Am I right?. But what is meant by "A *namespace* is a mapping from names to objects" Thanks Varuna
