aiohttp + aiocron

aiohttp_with_cronjob.py

# Example of running aiohttp and aiocron together
#
# Packages: aiohttp==3.8.1 aiocron==1.8
# Tested python version: python:3.10.0
# Issue: aircron not working once aiohttp start
# Solution Concept: Both share the same event loop

# A cronjob that run every minutes
# Assign the created event loop to aiocron
