Answer 1

import json
import boto3


roleARN = 'arn:aws:iam::account-of-role-to-assume:role/name-of-role'
client = boto3.client('sts')
response = client.assume_role(RoleArn=roleARN, 
                              RoleSessionName='RoleSessionName', 
                              DurationSeconds=900)

dynamodb_client = boto3.client('dynamodb', region_name='us-east-1',
                    aws_access_key_id=response['Credentials']['AccessKeyId'],
                    aws_secret_access_key=response['Credentials']['SecretAccessKey'],
                    aws_session_token = response['Credentials']['SessionToken'])

response = dynamodb_client.get_item(
Key={
    'key1': {
        'S': '1',
    },
    'key2': {
        'S': '2',
    },
},
TableName='TestTable')
print(response)
