Using aws-cli --query Option To Simplify Output - Alestic.com
Nice little tutorial demonstrating how to capture AWS command output from Bash Shell scripts into variables to use in scripts.

e.g. Get the status of an RDS Instance e.g. started, stopped, starting, stopping, modifying that sort of thing. You can do it like this:

rds_instance_status=$(aws --profile my-profile rds describe-db-instances --db-instance-identifier helis-staging-rds-instance-1 --query 'DBInstances[0].DBInstanceStatus')

Note that the query option drills down the output, which, by default is returned as JSON text.

MySQLdb User's Guide
I don't get it, but I guess you're supposed to use %s as a placeholder even for integers (so not %d) in a query string that is used in a cursor.execute() statement. I tried it with pymysql. I'm not sure why, but it worked.

This is the explanation: In this example, max_price=5 Why, then, use %s in the string? Because MySQLdb will convert it to a SQL literal value, which is the string '5'. When it's finished, the query will actually say, "...WHERE price < 5".
