Bloomberg API, pybbg

Question

I'm trying to extract bloomberg data using the BDS formula in python and I have downloaded the pybbg library. I want to include several overrides but I get an error. What I'm trying to extract is done following with the excel API addin: =BDS("SUBC NO Equity","PG_REVENUE","PRODUCT_GEO_OVERRIDE=G","FUND_PER=Q"= For one override, following code works (https://github.com/kyuni22/pybbg):

import unittest
import datetime
import pybg

class TestPybbg(unittest.TestCase):
    def test_bds(self):
        tester = pybbg.Pybbg()
        data = tester.bds('SUBC NO Equity','PG_REVENUE',overrides={'FUND_PER': 'Q'})
        print(data)

if __name__ == '__main__':
    unittest.main()

Following Error arises if the Company doesn't have that level detail:

Answer 1

I figured it out, if you add the following to the formula you can include several overrides:

data = tester.bds('SUBC NO Equity','PG_REVENUE',overrides={'PRODUCT_GEO_OVERRIDE':'G','FUND_PER':'Q'})
