If you’re among the Python developers put off by asyncio’s complexity, it’s time to take another look. Asyncio is complicated because it aims to solve problems in concurrent network programming for both framework and end-user developers. The features you need to consider are a small subset of the whole asyncio API, but picking out the right features is the tricky part. That’s where this practical book comes in. Veteran Python developer Caleb Hattingh helps you gain a basic understanding of asyncio’s building blocks—enough to get started writing simple event-based programs. You’ll learn why asyncio offers a safer alternative to preemptive multitasking (threading) and how this API provides a simpleway to support thousands of simultaneous socket connections. Get a critical comparison of asyncio and threading for concurrent network programming Take an asyncio walk-through, including a quickstart guidefor hitting the ground looping with event-based programming Learn the difference between asyncio features for end-user developers and those for framework developers Understand asyncio’s new async/await language syntax, including coroutines and task and future APIs Get detailed case studies (with code) of some popular asyncio-compatible third-party libraries

It's easy to overload standard Python and watch your programs slow to a crawl. The asyncio library was built to solve these problems by making it easy to divide and schedule tasks. It seamlessly handles multiple operations concurrently, leading to apps that are lightning fast and scalable. "Python concurrency with asyncio" introduces asynchronous, parallel, and concurrent programming through hands-on Python examples. Hard-to-grok concurrency topics are broken down into simple flowcharts that make it easy to see how your tasks are running. You'll learn how to overcome the limitations of Python using asyncio to speed up slow web servers and microservices. You'll even combine asyncio with traditional multiprocessing techniques for huge improvements to performance.

Asynchronous programming is built into Python. The language directly supports coroutines as first-class objects with the async and await expressions for asynchronous programming. The asyncio module provides tools for creating and managing asynchronous task and for developing non-blocking I/O client and server programs. Asyncio is not coming, it's here. Skills in asyncio are in demand and the demand is growing. Asynchronous programming and asyncio are how we develop modern scalable event-driven programs in Python. This paradigm dominates modern Python web development, API development, and network programming, and there are few Python programs that do not touch on these areas. Developing concurrent programs using coroutines and the asyncio module API can be very challenging, especially for Python developers who are new to asynchronous programming. Introducing: "Python Asyncio Mastery". A new book designed to teach you asyncio in Python, super fast! You will get fast-paced tutorials showing you how to develop asyncio programs on advanced topics. Including: * How to define, schedule, execute, check the status, and get results from asynchronous tasks. * How to manage groups of asynchronous tasks, including waiting for tasks, getting results, grouping tasks and using timeouts. * How to use more advanced features of tasks such as shielding, sleeping, waiting for, and executing blocking tasks. * How to define, create, and use asynchronous iterators, generators, context managers, and queues. * How to safely synchronize and coordinate the behavior of coroutines with mutex locks, semaphores, barriers, and more. * How to run commands and perform non-blocking inter-process communication with subprocesses. * How to develop clients and servers with socket programming and perform non-blocking reads and writes. Each tutorial is carefully designed to teach one critical aspect of how to use asyncio in your Python programs. Learn Python asyncio correctly, step-by-step.

BRIDGE THE GAP BETWEEN NOVICE AND PROFESSIONAL You've completed a basic Python programming tutorial or finished Al Sweigart's bestseller, Automate the Boring Stuff with Python. What's the next step toward becoming a capable, confident software developer? Welcome to Beyond the Basic Stuff with Python. More than a mere collection of advanced syntax and masterful tips for writing clean code, you'll learn how to advance your Python programming skills by using the command line and other professional tools like code formatters, type checkers, linters, and version control. Sweigart takes you through best practices for setting up your development environment, naming variables, and improving readability, then tackles documentation, organization and performance measurement, as well as object-oriented design and the Big-O algorithm analysis commonly used in coding interviews. The skills you learn will boost your ability to program--not just in Python but in any language. You'll learn: Coding style, and how to use Python's Black auto-formatting tool for cleaner code Common sources of bugs, and how to detect them with static analyzers How to structure the files in your code projects with the Cookiecutter template tool Functional programming techniques like lambda and higher-order functions How to profile the speed of your code with Python's built-in timeit and cProfile modules The computer science behind Big-O algorithm analysis How to make your comments and docstrings informative, and how often to write them How to create classes in object-oriented programming, and why they're used to organize code Toward the end of the book you'll read a detailed source-code breakdown of two classic command-line games, the Tower of Hanoi (a logic puzzle) and Four-in-a-Row (a two-player tile-dropping game), and a breakdown of how their code follows the book's best practices. You'll test your skills by implementing the program yourself. Of course, no single book can make you a professional software developer. But Beyond the Basic Stuff with Python will get you further down that path and make you a better programmer, as you learn to write readable code that's easy to debug and perfectly Pythonic Requirements: Covers Python 3.6 and higher
