我得到所有标准普尔500指数股票的列表，然后存储每个股票信息，其中包含大量财务信息，每个股票在数据框架中约有170列，代码非常慢，我想知道它是否可以改进。
import pandas as pd
import yfinance as yf
import json
import datapackage
data_url = 'https://datahub.io/core/s-and-p-500-companies/datapackage.json'
# to load Data Package into storage
package = datapackage.Package(data_url)
# to load only tabular data
resources = package.resources
for resource in resources:
if resource.tabular:
data = pd.read_csv(resource.descriptor['path'])
spSymbols=data['Symbol']
sp500 =""
for i in spSymbols:
sp500= sp500 + i +" "
tickers= yf.Tickers(sp500)
dfStockInfo =[]
metricList=[]
#bottle neck ****
for i in spSymbols:
stock = tickers.tickers.get(i)
stockInfo= stock.info
metricList.append(stockInfo)
我想通过尝试批量调用来优化tickers.tickers.get(i)。对于每个股票，它都进行API调用。我原以为tickers= yf.Tickers(sp500)这行可以一次得到所有的股票信息，但似乎没有。谢谢!
您无法改进这一点，因为对于每个计时器，您将接收155列:
metricList = []
for t in small:
metricList.append(pd.DataFrame([yf.Ticker(t).info]))
df = pd.concat(metricList)
是(对于前五个股票):
