How to query database by id using SqlAlchemy?

I need to query a SQLAlchemy database by its id something similar to User.query.filter_by(username='peter') but for id. How do I do this? [Searching over Google and SO didn't help]
Query has a get function that supports querying by the primary key of the table, which I assume that id is. For example, to query for an object with ID of 23: User.query.get(23) Note: As a few other commenters and answers have mentioned, this is not simply shorthand for "Perform a query filtering on the primary key". Depending on the state of the SQLAlchemy session, running this code may query the database and return a new instance, or it may return an instance of an object queried earlier in your code without actually querying the database. If you have not already done so, consider reading the documentation on the SQLAlchemy Session to understand the ramifications.
