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

Asynchronous versus other programming models

Asynchronous programming is one of the major concepts in concurrency specifically, and in programming in general. However, it is quite a complex concept that can be considerably challenging for us to sometimes differentiate it from other programming models. In this section, we will be comparing asynchronous programming with synchronous programming and other concurrent programming models that we have seen (that is, threading and multiprocessing).

Asynchronous versus synchronous programming

Again, asynchronous programming is fundamentally different from synchronous programming because of its task-switching nature. In synchronous programming, the instructions of a program are executed...
