Concurrent.futures example
The concurrent.futures module was added in Python 3.2. According to the Python documentation it provides the developer with a high-level interface for asynchronously executing callables. Basically concurrent.futures is an abstraction layer on top of Python’s threading and multiprocessing modules that simplifies using them. In this example, we write a simple message on the output to let the user know the program is performing the calculation. The method get() will block the execution until the task is complete. But we don't have to worry about that since our example only get to the point where get() is called after making sure that the task is finished. Easy parallel python with concurrent.futures. As of version 3.3, python includes the very promising concurrent.futures module, with elegant context managers for running tasks concurrently. Thanks to the simple and consistent interface you can use both threads and processes with minimal effort. The concurrent.futures modules provides interfaces for running tasks using pools of thread or process workers. The APIs are the same, so applications can switch between threads and processes with minimal changes. The module provides two types of classes for interacting with the pools. The concurrent.futures module provides a high-level interface for asynchronously executing callables. The asynchronous execution can be performed with threads, using ThreadPoolExecutor, or separate processes, using ProcessPoolExecutor. Both implement the same interface, which is defined by the abstract Executor class. I want to enable parallel processing/threading of my program using the concurrent.futures module. Unfortunately I can't seem to find any nice, simple, idiot-proof examples of using the concurrent.futures module. They typically require more advanced knowledge of python or processing/threading concepts and jargon. concurrent.futures — Asynchronous computation¶ The concurrent.futures module provides a high-level interface for asynchronously executing callables. The asynchronous execution can be be performed by threads using ThreadPoolExecutor or seperate processes using ProcessPoolExecutor .

18 Mar 2018 This example uses map() to concurrently produce a set of results from an input iterable. The task uses time.sleep() to pause a different amount of 16 Oct 2019 Some examples of how I've been using concurrent.futures to speed up the tasks are slow – for example, making HTTP requests – and I want For example say you have to make 1000 network requests, using concurrent. futures will make it so you don't get stuck waiting for a few slow network responses 25 Mar 2018 The two key ways to use the futures.Executor map method (via threads or processes) and their pros and cons; Some useful sample and 3 Aug 2016 The concurrent.futures module was added in Python 3.2. According to the Python This sounds kind of confusing, so let's look at an example:

The module is part of the standard library since Python 3.2 . Let's look at a simple example.
