[PYTHON] use something other than the default profile with boto3

By default

import boto3

s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
    print(bucket.name)

Specify ACCESS_KEY and SECRET_KEY

import boto3
from boto3.session import Session

session = Session(aws_access_key_id='<YOUR ACCESS KEY ID>',
                  aws_secret_access_key='<YOUR SECRET KEY>',
                  region_name='<REGION NAME>')

s3 = session.resource('s3')

Specify by profile name in ~ / .aws / credentials

Pass profile_name to Session.

Documentation I can't understand it by looking at it, [github issue](https://github.com/boto/boto3/pull/ Found in 69)

import boto3
from boto3.session import Session

profile = '<YOUR_PROFILE_NAME>'
session = Session(profile_name=profile)

s3 = session.resource('s3')
