Boto3 is AWS's python library for interacting with the AWS API. As everything (even the console under the surface) is API based, boto3 allows you to do pretty much everything you can do elsewhere. It may not always be up to date enough to follow new feateres, so ensure you have a up to date copy of the library with pip.

def get_account_number():
    stsclient = boto3.client("sts")
    response = stsclient.get_caller_identity()["Account"]
    return response

print(get_account_number())
