关于财务数据获取按季度的问题，这里应该是有误的。其实帖子里面也指出来了，应该是按年度取到的就是按年汇总后的， 而不是q4季度的，通过执行下代码就知道
```
years = ["2019","2019q1","2019q2","2019q3","2019q4"]
df_list = []
for year in years:
q = query(valuation.code, (cash_flow.net_operate_cash_flow).label("nocf")).filter(valuation.code.in_(stock_list))
df_year = get_fundamentals(q, statDate=year).set_index('code')
df_list.append(df_year)
df = pd.concat(df_list, axis=1, keys=years)
dfq = (df[years[1]]+df[years[2]]+df[years[3]]+df[years[4]])
dfq.columns = ["dfq"]
result = pd.concat([dfq,df[years[0]]], axis=1)
result
```
