Namespaces in Python: Built-in, Global, Enclosing, and Local

What are the namespaces in Python? In a program of any complexity, you’ll create hundreds or thousands of names, each pointing to a specific object. How does Python keep track of all these names so that they don’t interfere with one another? This video covers Python namespaces, the structures used to organize the symbolic names assigned to objects in a Python program.

Since you are working with an interactive version of python,
you fail to mention which namespace is being referenced when
executing globals().

In a multi module application (most applications) merely executing
globals() at the interactive prompt gives different results depending
on where it is executed. The truth is that globals() is accessing
the "current" namespace or "current" module.

Python took a perfectly good word - "globals" - and is using that word
to really mean "module" scope.

Python, does not truly have anything resembling "global" variables
or "global" functions as defined in other programming languages.
This difference is an ongoing source of confusion and quirky programming
errors. I suggest you consder multi module applications when you speak of "globals"...

so what is a namespace, it looks like a JSON string to me, do we need to use it when programming python
