Python Recipes vs tocsiapp

An everyday Python reference, from strings and collections to threading and design patterns. Tricky parts of the examples are explained in comments. You know what you need, but the exact syntax escapes you: • How do I sort a dict by value? • How do I serialize an object to JSON and back? • How do I start a thread and wait for it to finish? Each of these has a ready, working example here; just adapt it to your code. • 22 sections, including basic types, arrays and collections, classes, files, serialization, functions and lambdas, exceptions, regular expressions, threading, databases, algorithms, design patterns. • Language changes by version: 8 sections from Python 3.0 to 3.13, with before-and-after code. • Keyword and function reference: over 200 articles. Browse, search, or tap a word in the code to open its article. • SQL included: over 200 queries (JOIN, GROUP BY, subqueries, data types); more than half run on a real practice database. • Run in the app: the output appears directly below the code, no IDE or local Python needed. More than 90% of examples run. Requires an internet connection. • Search covers the code itself, not just titles: type a fragment you remember and find the example. • Edit examples or add your own; your changes and additions are saved in the app. • Everything except running code works offline. No account needed. Examples are curated from professional sources and checked before release: the code works and is easy to follow. FREE VERSION • 12 runs (examples and SQL combined) and 12 edits a day • Full keyword and function reference, no limits • Up to 5 examples of your own The full version unlocks every example and query, removes the limits on edits and on your own examples, and raises the daily run limits to 30 for examples and 80 for SQL. One-time purchase, no subscription. Built by a developer for developers. The CodePro project has been in active development since 2015.
