Boto3 uses old credentials

Question

I am using tkinter to create gui application that returns the security groups. Currently if you want to change your credentials (e.g. if you accidentally entere

Answer 1

You need boto3.session.Session to overwrite the access credentials.

Just do this reference http://boto3.readthedocs.io/en/latest/reference/core/session.html

import boto3

# Assign you own access 
mysession = boto3.session.Session(aws_access_key_id='foo1', aws_secret_access_key='bar1')

# If you want to use different profile call foobar inside .aws/credentials
mysession = boto3.session.Session(profile_name="fooboar")

# Afterwards, just declare your AWS client/resource services    
sqs_resource=mysession.resource("sqs")

# or client 
s3_client=mysession.client("s3")

Basically, little change to your code. you just pass in the session instead of direct boto3.client/boto3.resource

self.sts_client = mysession.client('sts')
