Python & SQL Pro vs Learn Python (Step By Step)

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; the daily limit is 30 launches. • 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, browsable as a list and searchable. • SQL alongside: 243 queries against a live practice database - JOIN, GROUP BY, subqueries, data types. Queries have their own daily count. • 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: examples, search, favourites. No account needed. • Light and dark themes, font and size, line numbers, soft wrapping. Every example is picked from trusted sources and thoroughly tested. Made by a developer for developers. In development since 2015.
