• sqlalchemy
  • tuple

The question is about why a simple single column query such as

>>> results = session.query(MyModel.id).all()

results in a list of tuples of id (and/or what to do about it):

>>> results
[(1,), (2,), (3,), (4,)]

instead of a list of ids. A simple solution is to iterate over the results and
use unpacking:

>>> [value for value, in results]
[1, 2, 3, 4]
