Python for Pros: Code Lab

You can already know Python — now you'll learn how professionals work with it. This course takes you from data modelling to decorators, tests and asyncio to your own network protocols and REST clients.

CODE THAT REALLY WORKS
You can run each example directly in the app, change it, and start it again. Python runs on your device — lessons, exercises, and exams also work offline.

48 LESSONS IN 8 CHAPTERS
• The Python data model: references, iterators, generators, pattern matching, bytes and Unicode
• Functions: *args/**kwargs, Closures, Decorators, functools, Type Hints
• Object Orientation: MRO, Properties, Dataclasses, Protocols, Dunder Methods, Context Manager
• Quality: own exceptions, logging, unittest, TDD, debugging, refactoring
• Data: collections, itertools, regular expressions, JSON/CSV, time zones, pathlib
• Performance: Big-O, timeit, __slots__, asyncio, tasks, queues and timeouts
• Networking: TCP/UDP, sockets, own protocols, HTTP, URLs, REST APIs with retry
• Architecture: packages, argparse and four large projects

NETWORKING TO TOUCH
The app includes a simulated network with Echo servers, DNS, and a REST API. You write real socket and asyncio code — the same code runs on your own computer with the normal socket module.

LAB: 144 TASKS WITH AUTOMATIC EXAMINATION
Three tasks per lesson (medium, difficult, expert) with hidden tests, plus 8 chapter projects with 40 to 120 lines. The app shows you exactly which case is still wrong.

EXAMINATIONS AND CERTIFICATE
480 quiz questions, 8 chapter tests and a final exam with 40 questions and 4 programming tasks in 90 minutes. If you pass everything, you will receive a personal certificate as a PDF.

IN ADDITION
• Learning video for each lesson (online)
• Lexicon with all technical terms
• Playground for own programs
• Night mode and customisable font size
• 9 languages

Buy once, use forever. No subscription, no advertising, no data collection.

The certificate is a proof of learning of this app and not a state-recognised degree. Python is a brand of the Python Software Foundation; this app is an independent learning offering.
