Is there anyway to iterate database object and call them?

Question

I have a database object db with fields

db.one = 1
db.two = 2
db.three = 3

Is there any way to do something like

require_comparison_list = ["one", "three"]
for field in dir(db):
   if field in reqire_comparison_list:
       print(db.field)

where db.field will give me 1 and 3.

Thank you
