[PYTHON] About the uncluttered arrangement in the import order of flake8

from sqlalchemy import Column
from sqlalchemy import or_

In the above cases, I100 warning may be issued, and the warning cannot be set to 0 no matter how the order is changed, and as a result, the code below is settled.

from sqlalchemy import Column

from sqlalchemy import or_

Since this kind of thing often occurs in other packages, I investigated it, but in such a case, it seems that the cause is that it is specified by a path that can simply access the package.

In the case of the above example, it seems that this is the correct one.

from sqlalchemy import Column

from sqlalchemy.sql.expression import or_

Since the above is the official path, it should not be lined up with sqlalchemy.

It's a hassle to write so far, so as a result, I settled down in this way.

from sqlalchemy import Column

from sqlalchemy.sql import or_

Be careful about paths that can be abbreviated (only when using import order).
