Asyncio is an exciting new addition to Python. It allows regular Python programs to be developed using the asynchronous programming paradigm. It includes changes to the language to support coroutines as first-class objects, such as the async def and await expressions, and the lesser discussed async for and async with expressions for asynchronous iterators and context managers respectively. Asyncio is the way to rapidly develop scalable Python programs capable of tens or hundreds of thousands of concurrent tasks. Developing concurrent programs using coroutines and the asyncio module API can be very challenging for beginners, especially those new to asynchronous programming. Introducing: "Python Asyncio Jump-Start". A new book designed to teach you asyncio in Python, super fast! You will get a rapid-paced, 7-part course focused on getting you started and make you awesome at using asyncio. Including: * How to define, schedule, and execute asynchronous tasks as coroutines. * How to manage groups of asynchronous tasks, including waiting for all tasks, the first that, or the first task to fail. * How to define, create, and use asynchronous iterators, generators, and context manages * How to share data between coroutines with queues and how to synchronize coroutines to make code coroutine-safe. * How to run commands as subprocesses and how to implement asynchronous socket programming with streams. * How to develop a port scanner that is nearly 1,000 times faster than the sequential version. Each of the 7 lessons was carefully designed to teach one critical aspect of asyncio, with explanations, code snippets, and complete examples. Each lesson ends with an exercise for you to complete to confirm you understood the topic, a summary of what was learned, and links for further reading if you want to go deeper.

Unlock concurrency with Python threads (and run 100s or 1,000s of tasks simultaneously) The threading module provides easy-to-use thread-based concurrency in Python. Unlike Python multiprocessing, the threading module is limited by the infamous Global Interpreter Lock (GIL). Critically, the GIL is released when performing blocking I/O. Additionally, threads can share memory making them perfectly suited to I/O-bound tasks such as reading and writing from files and socket connections. This is the API you need to use to make your code run faster. Introducing: "Python Threading Jump-Start". A new book designed to teach you the threading module in Python, super fast! You will get a rapid-paced, 7-part course to get you started and make you awesome at using the threading API. Each of the 7 lessons was carefully designed to teach one critical aspect of the threading module, with explanations, code snippets and worked examples. You will discover: * How to choose tasks that are well suited to threads. * How to create and run new threads. * How to locate and query running threads. * How to use locks, semaphores, barriers and more. * How to share data between threads using queues. * How to execute ad hoc tasks with reusable worker threads. * How to gracefully stop and forcefully kill threads.

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.
