The namespace is a Python dictionary, which contains key-value pairs, which are variable identifiers as keys and their values. That it looks like JSON is just because it's logically the same structure, and the print function in Python is apparently overloaded to display dicts like this.
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"...
Hi, may I ask what other languages you were referring to when you said "python doesn't truly have anything resembling global variables as defined in other programming languages".
Why Did not covered
what is namespaces ???
you started from type of namespaces...
i was about to ask that
Really helpful. Thanks a lot for your effort. The best example for a good teaching style.
Thank you very much for this video! It is very educational :)
Amazing video, very useful! Unrelated: are you dutch? :D
I have a little question why is the print function not copied to the local namespace ?
Great info! Thanks this makes it very clear and is super helpful.
????????????????????????? so what is a namespace, it looks like a JSON string to me, do we need to use it when programming python ?????

Excellent video thanks !
Where is the next episode? I need it...

@@v4n5h4j I think C++ and JS can be taken as example for that.
i like how u call underscores as dunders or w/e lol so funny
1.5x speed ^.^
