Question

我正在尝试使用python中的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收到错误。我正在尝试提取的内容是使用excel API addin：= BDS（“SUBC NO Equity”，“PG_REVENUE”，“PRODUCT_GEO_OVERRIDE = G”，“FUND_PER = Q”= 对于一个覆盖，以下代码有效（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()

如果公司没有该级别详细信息，则会出现以下错误：

我想通了，如果你在公式中添加以下内容，你可以包含几个覆盖：

def parse(u):
    u = u.rstrip('\n')
    r = requests.get(u, headers=headers)
    if r.status_code == 200:
        html = r.text.strip()
        soup = BeautifulSoup(html, 'lxml')
        headings = soup.select('table p')
        for h in headings:
            b = h.find('b')
            if b is not None:
                print(b.text)
                print(h.text + '\n')
                print('=================================')
