These are a few of my favorite PEPs, or Python Enhancements Proposals I’ve encountered recently. PEP 0, PEP 8 and PEP 20 are great reads for those aspiring to hone their Python skills. The documentation sometimes references specific PEPs directly also. They document Python’s evolution over time and the rationale behind it. Here are some good ones to remember!
PEP 0 — Index of Python Enhancement Proposals
PEP 8 — Style Guide for Python Code
PEP 20 — The Zen of Python
PEP 249 — Python Database API Specification v2.0
PEP 3131 — Supporting Non-ASCII Identifiers
PEP 3333 — Python Web Server Gateway Interface v1.0.1
