How to use the aioconsole.compat function in aioconsole

To help you get started, we’ve selected a few aioconsole examples, based on popular ways it is used in public projects.

Secure your code as it's written. Use Snyk Code to scan source code in minutes - no build needed - and fix issues immediately.
