So, a Python fanboy. Well, I remember when I learned Python 5 years ago, I did all of these. Before that I did them all with C# 14 years ago, and before that I did the same with Java, VB, PHP, C/C++, ASP, HTML etc etc(you insert any fad in past 20 years, I've done it) all the way back to 90's when I started with Pascal and Assembler.

The general answer to all of them is "you grind and RTFM". I too am awaiting the time when all I need to be expert in a new technology is to just go buy the plugin I'll insert into my brain (hopefully we'll become cyborgs, that's my optimism) but until then is grind & RTFM.
