Should session be closed after each query in sqlalchemy?

I am using sqlalchemy orm query, I want to know if closing session after each query is really necessary?

def foo():
   session = get_orm_sqlalchemy_session()
   try:
      pass
   except Exception as ex:
      logging.error(str(ex), stack_info=traceback.print_exc())
   finally:
      session.close()

Closing the session after each query is a common practice to ensure that database connections are properly managed and resources are released.

There are several reasons why a session should be closed:

• ensure that database connections are returned to the connection pool and resources are freed.
• makes sure that all transactions are properly committed or rolled back, avoiding potenstial issues with lingering sessions
• ensure that the application remains in a consistent state when a session is closed in case of exceptions

Note that: scoped_session of SQLAlchemy provides thread-local sessions, the framework can handle session lifecycle automatically.
