彭博API，pybbg

Question

我想在python中使用BDS公式提取bloomberg数据，并且我已经下载了pybbg库。我想包括几个覆盖，但我得到一个错误。我试图提取的是使用excel API插件完成的：= BDS（“SUBC NO Equity”，“PG_REVENUE”，“PRODUCT_GEO_OVERRIDE = G”，“FUND_PER = Q”= 对于一个覆盖，以下代码工作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() 

跟随误差出现，如果公司不具备这个水平的细节：

Traceback (most recent call last): 
    File "C:/Users/bloomberg/.spyder-py3/temp.py", line 23, in test_bds_override 
    data = tester.bds('AKSO NO Equity','PG_REVENUE',overrides={'PRODUCT_GEO_OVERRIDE':'G','FUND_PER':'Q'})

Answer 1

我想通了，如果你添加下面的公式可以包括几个替代：

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