我面临一个问题。请帮助我

这是代码：

import pandas
import quandl
import time

df = quandl.get('FINRA/FNSQ_GOOGL')
print(df.head())

我面临的错误是：

import pandas 
import quandl
import time

df=''
while df=='':
try:
    df = quandl.get('FINRA/FNSQ_GOOGL')
except:
    time.sleep(5)
    print("try")
    continue
print(df.head())

如果有人帮助我解决这个问题，我将不胜感激。提前致谢！！

df = quandl.get('FINRA/FNSQ_GOOGL')对我来说效果很好。该错误表明证书验证失败，这意味着您的客户端无法验证服务器的证书。您可能需要更新您的 SSL CA 证书包。

您可以尝试升级certifi包：pip install -U certifi。我的系统正在使用certifi-2017.11.5.
