I didn't really mean to become a Python programmer. I was on my way to something with a little more rocket-science feel. R, Scala, Haskell, maybe. But, since I'm here, I may as well learn something about how to do it right. In this respect, I've become a fan of Raymond Hettinger.
Python coders will enjoy and benefit from Raymond's excellent talk given at PyCon 2015 about Python style, Beyond PEP 8 -- Best practices for beautiful intelligible code.
"Who should PEP-8-ify code? The author. PEP 8 unto thyself not unto others."
To Hettinger, PEP-8 is not a weapon for bludgeoning rival developers into submission. Going beyond PEP 8 is about paying attention to the stuff that really matters - using languages features like magic methods, properties, iterators and context managers. Business logic should be clear and float to the top. In short, writing beautiful idiomatic Pythonic code.
There are plenty more videos from PyCon 2015 where that one came from.
