Python Guides

Python Reference includes 48 in-depth guides that go beyond single-function documentation. Each guide opens with an introduction to the module or topic and then walks through its concepts in ordered sections with prose explanations and real code, so you can read it start to finish like a chapter of a book. Topics range from core language features such as built-in functions, strings, lists, and dictionaries to standard-library modules like os and concurrency and packaging topics. More guides: builtins, string, list, dict, os, re, math, file, datetime, json, csv, sqlite. Pair a guide with the matching category reference pages to look up individual functions, or practice what you learn in the Python playground.
