kandi X-RAY | coroutines-demo Summary

coroutines-demo is a Python library typically used in Programming Style, Reactive Programming, Framework applications. coroutines-demo has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

Script for live-coding an implementation of Python async coroutines analogous to asyncio.coroutine in the Python 3.4 standard library:. tornado.gen.coroutine is an earlier inspiration for the same idea. The example program is a "web crawler" that fetches only two URLs. Files are named in order. To run the examples, first start server.py in a separate terminal session. (It requires Flask.) server.py is designed to be slow - each URL takes about a second to download. This provides a good example of async’s strength suit.

QUESTION

Python: what does await do in the following context?

Asked 2020-Mar-28 at 23:47

I try to learn coroutines from example located at https://github.com/ajdavis/coroutines-demo/blob/master/50.py. It was created by user https://stackoverflow.com/users/618967/a-jesse-jiryu-davis in 2015.

I see await f multiple times in the code. f was an empty Future, why it needs to be await. Can someone explain this concept in a more cleary way?

This code is a kind of weird way to use await. Most code that uses await doesn't interact with the coroutine implementation as directly as this code does.

Python coroutines are implemented on top of the old iterator and generator machinery, with a little extra enforcement to avoid mixing them up. get works like a generator, and await f works like yield from f.__await__() would if f were a generator. Since f.__await__ is implemented as yield self, await f behaves like yield f. (Don't try replacing await f with any sort of yield - manually yielding doesn't work the same way in a coroutine.)

The code you're looking at wraps all get coroutines in a Task object, and Task.step looks like this:

The problem is that async (the same as launch) is defined as an extension function on CoroutineScope. In the following example, it is invoked in the receiver CoroutineScope of withContext:

The simplest way to solve your issue is to replace

compile(kotlin ("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.0"))

with

compile("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.0")

So why do you need to remove kotlin function? If you check its source code (below) you will see that it appends module name to string "org.jetbrains.kotlin:kotlin-" so in your case the final string becomes "org.jetbrains.kotlin:kotlin-org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.0" which is obviously invalid and should cause an error (but it doesn't, so it is a bug).
