There's no tablet of stone, like PEP 8 :-) It seems to be a matter of
individual taste; clarity and consistency and not overdoing
parentheses count for me.
IMO you have too much leading whitespace, you have "as" in upper,
lower and no case, and I'd set out the inner select differently:
query = """
SELECT * FROM (
SELECT a.columna, a.columnb, a.iso
FROM all AS a
WHERE a.name = LOWER(%s)
) AS c
JOIN other AS b ON c.gid = b.id
WHERE class = 'A'
ORDER BY population DESC
LIMIT %s;
"""
