Python Recipes

A reference of everyday Python, from strings and collections to threading and design patterns. Every example is written out in full and explained.

• 22 sections: simple types, arrays and collections, classes, files, serialization, functions and lambdas, exceptions, regular expressions, threading, databases, algorithms, patterns.
• Run in the app: the example really executes and the output appears under the code. Needs an internet connection.
• What changed in new versions: eight sections from Python 3.0 to 3.13, with "before" and "after" code side by side.
• Keyword and function reference: 203 articles, fully open with no daily counter.
• SQL alongside: 243 queries against a live practice database - JOIN, GROUP BY, subqueries, data types.
• Edit any example and run it again; one tap brings the original back.
• Add your own examples - they are kept in the app and always at hand.
• Search by section name or by a fragment of code.
• Everything except running works offline. No account needed.
