I'm a fairly strong Python coder, but too much of my style is a little haphazard, and I'm sure there are more Pythonic solutions to many problems than the ones I come up with. Which PEPs are essential for any well versed Pythonista to read?
I'd also recommend PEPs 8 and 257. I know this deviates slightly from the original question, but I'd like to point out that PyCharm (probably the best Python IDE around in my opinion) automatically checks if you're following some of the most important PEP 8 guidelines, just in case anyone's interested...
Which PEP's are must reads?
