What are namespaces in Python

Question

I am new to Python & want to know about the concept of  "namespaces"  in Python. While I got the jist of what it is, but am unable to appreciate the gravity of this concept.Some browsing on the net revealed that one of the reasons going against PHP is that it has no native support for namespaces.

Can you explain how to use namespaces & how this feature makes programming better?

Answer 1

Namespace is basically a way to implement scope.

In Java or C the compiler determines where a variable is visible through static scope analysis.

In Python, each package, module, class, function and method function owns a "namespace" in which variable names are resolved. Plus there's a global namespace that's used if the name isn't in the local namespace.
