An async application runs entirely in a single process and a single thread, which is nothing short of amazing. Of course this type of concurrency takes some discipline, since you can't have a task that holds on to the CPU for too long or else the remaining tasks starve. For async to w...

There aren’t many truly new major features in Python 3.10, but of the few that we do have, one of them — structural pattern matching— may be the single most significant addition to the language syntax since async. Here’s a rundown of all of the major new features in Python 3.10,...
A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to define asynchronous generators: async def ticker(delay, to): """Yield numbers from 0 to...

Python's Global Interpreter Lock or GIL, in simple words, is a mutex (or a lock) that allows only one thread to hold the control of the Python interpreter at any one time. In this article you'll learn how the GIL affects the performance of your Python pr
Example of an Assertion in Playwright (JavaScript): const { test, expect } = require('@playwright/test'); test('Login page should display welcome message after login', async ({ page }) => { // Navigate to the login page await page.goto('https://example.com/login'); // Perform log...
This will visit our local page in a 1366x900 viewport. Then we create a promise to wait for the Snipcart script to finish loading by capturing thesnipcart.readyevent. All of Cypress’s functionality is available under the globalcyobject you can see above. There is no need for any async/...
Bennet warns against the temptation to use async for all the things, in a section cleverly entitled “Everything and the kitchen async” (Source). An event loop is good for certain applications but not others. To understand more about good applications for asynchronous Python, check out the Re...
