[4.0.x] Refs #33476 -- Refactored problematic code before reformatting by Black.

In these cases Black produces unexpected results, e.g.

def make_random_password(
    self,
    length=10,
    allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789',
):

or

cursor.execute("""
SELECT ...
""",
    [table name],
)
