Mastering Concurrency in Python

By: Quan Nguyen

Overview of this book

Python is one of the most popular programming languages, with numerous libraries and frameworks that facilitate high-performance computing. Concurrency and parallelism in Python are essential when it comes to multiprocessing and multithreading; they behave differently, but their common aim is to reduce the execution time. This book serves as a comprehensive introduction to various advanced concepts in concurrent engineering and programming. Mastering Concurrency in Python starts by introducing the concepts and principles in concurrency, right from Amdahl's Law to multithreading programming, followed by elucidating multiprocessing programming, web scraping, and asynchronous I/O, together with common problems that engineers and programmers face in concurrent programming. Next, the book covers a number of advanced concepts in Python concurrency and how they interact with the Python ecosystem, including the Global Interpreter Lock (GIL). Finally, you'll learn how to solve real-world concurrency problems through examples. By the end of the book, you will have gained extensive theoretical knowledge of concurrency and the ways in which concurrency is supported by the Python language

What is a communication channel? What is its connection to asynchronous programming?

Communication channels are used to denote both the physical wiring connection between different systems and the logical communication of data that facilitates computer networks. The latter is related to computing, and is more relevant to the idea of asynchronous programming. Asynchronous programming can provide functionalities that complement the process of facilitating communication channels efficiently.

What are the two main parts of the Open Systems Interconnection (OSI) model protocol layers? What purposes do each of them serve?

The media layers contain fairly low-level operations that interact with the underlying process of the communication channel, while the host layers deals with high-level data communication and manipulation.

What is the transport layer? Why is it crucial to...
