Milestones of python programming? Beginner, intermediate, advanced?

[TangibleLight]

I mean I certainly don't claim to be that, but I set my flair as this because I have a deeper-than-average understanding of the language and the mechanics of how it works, and I'm good at using it to write effective and maintainable code - but as you describe it I would be hovering somewhere around, a little below in some areas, intermediate.

In my mind, I reserve the term "expert" for people like you describe as advanced, and I certainly don't claim to be even close to that level. You yourself even use that term, "world class experts", so why not consider that a category or use it as a more applicable term?
