UPDATED QUESTION FOR CLARITY:
suppose I have 2 processing generator functions:

built-in function is just a convenient way of invoking the underlying __next__
method on the object. The async equivalent of __next__
is the __anext__
method on the async iterator. There is no anext
global function, but one could easily write it:
QUESTION
I've got a simple python3 webscraper which was working synchronously. I wanted to make it asynchronus, so I modified it a bit. But the program does not iterate over an unpacked list [(,), (,), (,), ...]
even after converting it into converting it into an iterable list using iter(). Says TypeError: 'list_iterator' object is not async iterable
.
Because my code is big, and I'm still learning asynchronous programming I'll put the main parts here with the Error.
My aim was to fetch the links asynchronously to speed up the process. Is there a way to solve this ?
Code :
...ANSWER
Answered 2018-Sep-11 at 11:16Yes, you need an asynchronous iterator here. After fixing it, it downloads the urls asynchronnously in order.
After asking the project maintainer on gihub, I understand how it actually works.

Install aiostream
You can use aiostream like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
