My little idea of how to run multiple web crawler instances simultaneously with big input file.

	# -- coding: utf-8 --
	"""To run multiple aiohttp instances concurrently.

	code snippets I found online all create a list tasks to run,
	but my example file abc.csv is too big, and contains 10 million rows,
	which cannot fit into limited memory on a AWS ec2.micro instance,
	so I use a global generator instead, to feed task dynamically.
	requires python version 3.6.4 for f string to work.
