To see how one goes from concurrency toasync/await, we'll write a real-world concurrent program – a TCP echo server that supposed to handle multiple clients simultaneously. We'll start with the simplest, sequential version of the server that is not concurrent. Then we'll make it concurrent...

But for simple jobs you won’t need to. Read and write data with streams in Python The best scenarios for async are long-running network operations, where the application may block waiting for some other resource to return a result. To that end, asyncio offers streams, which are high-...
The asyncio module in Python provides a framework for writing single−threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related operations. It allows us to write asynchronous code in a structured and ...
Every time we runawait(e.g.await resp.text()) we give control back to python (more specifically to theevent loopas we're going to see soon) to decide what to do in the meantime. In other words,async only "works" when you have to wait for IO operations. ...

Note: In practice, you’re unlikely to write your own infinite sequence generator. The itertools module provides a very efficient infinite sequence generator with itertools.count(). Now that you’ve seen a simple use case for an infinite sequence generator, let’s dive deeper into how generators...

Multiparadigm: It lets you write code in different styles, including object-oriented, imperative, and functional style. Dynamically typed: It checks variable types at runtime, so you don’t need to declare them explicitly. Strongly typed: It won’t let unsafe operations on incompatible types go...
