You can use "named profile" to have multiple credentials settings. See https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html

[myprofile]  # or [default]
aws_access_key_id=[copy from csv]
aws_secret_access_key=[copy from csv]
region=us-east-2  # wherever you want

Usage

Run Script

If you use [myprofile], you need to specify AWS_PROFILE environment variable.

export AWS_PROFILE=myprofile

If you use [default] section, you can omit AWS_PROFILE.

python ec2_spot_price.py -i g3.4xlarge,p2.xlarge
