Default Region in collect.py code

[vnandyal]

Note the Network Visualization functionality (command prepare) is no longer maintained.

Code being called - collect.py
Working out of a virtualenv environment and Docker

I have a few questions regarding the default region in the collect.py code.

1. What does the following code snippet do ?

default_region = os.environ.get("AWS_REGION", 'us-east-1')

if 'gov-' in default_region:
    default_region = 'us-gov-west-1'
elif 'cn-'  in default_region:
    default_region = 'cn-north-1'
else:
    default_region = 'us-east-1'

2. Does the code in the snippet set the default region to us-east-1 if the other conditions are not met ?
3. What if I have a default region set to us-west-1 in my aws config ? Will us-west-1 be used instead of the above ?

Can anyone respond to my queries?

Seems like it gets the environment variable 'AWS_REGION' and if its not set it makes the default region be 'us-east-1', but I am guessing.
