concurrent.futures

Concurrency is a powerful concept in programming that allows us to perform multiple tasks simultaneously, making our applications faster and more responsive. In Python, the concurrent.futures module provides a high-level interface for asynchronously executing callables, which can be a game changer when dealing with I/O-bound or CPU-bound tasks.

In this chapter, we will explore the features and functionalities of the concurrent.futures module, focusing on its two primary classes: ThreadPoolExecutor and ProcessPoolExecutor.

We'll dive into practical code examples to illustrate how to use these tools effectively, discuss real-world applications, and touch on some common pitfalls that you might encounter along the way.
