Why do we want to write asynchronous programs you say — because it could increase the performance of your program many many times. Imagine you have a single core machine you are running your app on. You receive a request, and you need to make two database queries to fulfil that request. Each query takes 50ms of time. With a synchronous program, you would make the second request only after completing the first — total time 100ms. With an asynchronous program, you could fire off both the queries one after the other — total time 50ms.
asyncio
Asyncio is all about writing asynchronous programs in Python. Asyncio is a beautiful symphony between an Event loop, Tasks and Coroutines all coming together so perfectly — it’s going to make you cry.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
