Python Concurrency with asyncio

Learn how to speed up slow Python code with concurrent programming and the cutting-edge asyncio library.

    Use coroutines and tasks alongside async/await syntax to run code concurrently
    Build web APIs and make concurrency web requests with aiohttp
    Run thousands of SQL queries concurrently
    Create a map-reduce job that can process gigabytes of data concurrently
    Use threading with asyncio to mix blocking code with asyncio code

Python is flexible, versatile, and easy to learn. It can also be very slow compared to lower-level languages. Python Concurrency with asyncio teaches you how to boost Python\'s performance by applying a variety of concurrency techniques. You\'ll learn how the complex-but-powerful asyncio library can achieve concurrency with just a single thread and use asyncio\'s APIs to run multiple web requests and database queries simultaneously. The book covers using asyncio with the entire Python concurrency landscape, including multiprocessing and multithreading.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the technology
Its easy to overload standard Python and watch your programs slow to a crawl. Th e 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.

About the book
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. Youll learn how to overcome the limitations of Python using asyncio to speed up slow web servers and microservices. Youll even combine asyncio with traditional multiprocessing techniques for huge improvements to performance.
