How does the Python database orm framework SQLAlchemy exclude specified fields and not map / serialize specified fields when mapping fields?

as shown in the figure below, does SQLAlchemy have a simple way to directly declare that the specified field is not mapped / serialized?

for example, does java"s Hibernate framework have such a function?

(although there are other "indirect" solutions, but not convenient enough)
