With the advent of asynchronous in Python, I refer to asyncio, we sometimes find ourselves in situations where we would like to use an asynchronous library in an existing synchronous program. Except that coroutines are not made to work in the synchronous world. Well… that was before introducing you to the following library.😁

Greenletio solves this issue with a bit of magic using the greenlet library. So let’s see how it works.

Installation

To use Greenletio, we will need Python 3.7 or higher.

$ pip install greenletio
# or
$ poetry add greenletio
