使用python的证券交易所所有股票代码的市值

Question

我需要获取证券交易所（纽约证券交易所和纳斯达克）所有股票代码的当前市值以及它们的其他信息，例如收盘价、开盘价等（但这些是可选的）。

有没有像 csv 文件或 api 请求这样的方法可以给我这些信息？

我认为yfinance api没有这个功能来返回所有股票的市值，对吧？

Answer 1

使用像 Financial Modeling Prep 这样的 API。

import pandas as pd
import requests

FMP_key = 'YOUR API KEY HERE'

# Define lists of symbols and market caps
symbols = []
market_caps = []

# Define a function to get the url based on your API key and 
def url(symbol: str, api_key):
    return "https://financialmodelingprep.com/api/v3/market-capitalization/" + symbol + "?apikey=" + api_key

# All the symbols you want the data for
all_symbols = ['AAPL', 'MSFT', 'NFLX', 'NVDA', 'FB', 'TWTR', 'TSLA', 'AMZN', 'WMT']

# DataFrame to store all the data
data = pd.DataFrame(columns = ['Symbol', 'Market Cap'])

# Iterate based on the symbols list and add to DataFrame
for item in all_symbols:
    response = requests.get(url(symbol = item, api_key = FMP_key)).json()

    symbols.append(response[0]['symbol'])
    market_caps.append(response[0]['marketCap'])
    
# Add data to the dataframe
data['Symbol'] = symbols
data['Market Cap'] = market_caps

结果：

Answer 2

以下代码示例对您有用吗？如果没有，我有几个替代示例脚本。

import requests
from bs4 import BeautifulSoup
from pandas import DataFrame
import itertools
import numpy as np
from itertools import chain

url_base = "https://finviz.com/quote.ashx?t="

tckr = ['MSFT','AAPL','AMZN']
        
i = 1

url_list = [(s, url_base + s) for s in tckr]
data_list = []

headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0'}

for t, url in url_list:
    print(i)
    i = i + 1
    print(t, url)
    print('Scrapping ticker {}...'.format(t))
    soup = BeautifulSoup(requests.get(url, headers=headers).content, 'html.parser')
    #writer.writerow([t])
    l = []
    for row in soup.select('.snapshot-table2 tr'):
        l.append([td.text for td in row.select('td')])
        x = list(chain.from_iterable(l))
        d = dict(zip(x[::2], x[1::2]))
        d['Index'] = t
        
    data_list.append(d)

-- 结果：
