Python Recipes app analytics for September 8

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. WHAT THE FREE VERSION INCLUDES 12 runs and 12 edits a day - the counter resets every morning. The keyword reference is open without limits. Up to 5 examples of your own. Copying in the free app is blocked after five attempts. The full version opens all 644 examples, removes the daily limits and raises running to 30 launches a day. One purchase, no subscription. Made by a developer for developers. In development since 2015.
