import boto3

consumer = boto3.consumer('rds')

response = consumer.describe_db_engine_versions(
    DBParameterGroupFamily='mysql5.6',
    DefaultOnly=True,
    Engine='mysql',
    EngineVersion='5.6',
    ListSupportedCharacterSets=True,
)

print(response)

When the above code is run we get an output as under −
