Defining multiple entities #4321

Hi! I would like to have multiple entities defined and use them in different Feature Views. Currently I have one entity defined as
account = Entity( name="id_account", join_keys=["id_account"], value_type=ValueType.STRING, description="The account id")

and I want to add another entity like
other_entity = Entity( name="other_id", join_keys=["other_id"], value_type=ValueType.STRING, description="Different id, identifies a person")

The question is: Is it correct to define the entities that way, one just behind the other? Or how should I define them?
