A namespace is a set of currently declared symbolic names and information on the item to which each name refers.

Consider a namespace to be a dictionary, with the keys being the object names and the values being the objects themselves.

In Python, a namespace is a mechanism to provide a unique name for each object.

In Python, everything is an object, such as a variable or a method.

In other words, it is a collection of the declared symbolic names and information on the object to which each name refers.
