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

Summary

In this chapter, we provided a high-level analysis of concurrent programs in Python, via scheduling, testing, and debugging. Scheduling can be done in Python via the APScheduler module, which provides powerful and flexible functionalities to specify how scheduled jobs should be executed later on in the future. Furthermore, the module allows scheduled jobs to be distributed and executed across different threads and processes, offering a concurrency improvement in testing speed.

Concurrency also introduces complex problems in terms of testing and debugging, resulting from simultaneous and parallel interactions between the agents in a program. However, these problems can be approached effectively, with methodical solutions and the appropriate tools.

This topic marks the end of our journey through Mastering Concurrency in Python. Throughout this book, we have considered and...
