从雅虎财经获取股票价格的问题

Question

我正在从 yahoo Finance（NVIDIA 股票）进行一些网络抓取，我想知道为什么当我运行我的代码时我总是得到相同的值，但是在我的浏览器中当我刷新页面时我得到不同的值（如它应该是），我该如何解决它？

import requests
from datetime import datetime
import time

def Is_Number(string):
    try:
        int(string)
        return True
    except:
        if(string == '.'):
            return True
        else:
            return False



session = requests.Session()
for i in range(10):

    Response = session.get("https://finance.yahoo.com/quote/NVDA?p=NVDA")

    KeyWord = 'data-pricehint'
    Index = Response.text.find(KeyWord) + 26

    GoOn = True
    CurrentPrice = ""
    while(GoOn == True):

    if ( Is_Number(Response.text[Index])):
        CurrentPrice = CurrentPrice + Response.text[Index]
        Index = Index + 1
    else:
        GoOn = False

    CurrentTime = datetime.now().strftime('%H:%M:%S')

    print("# Price:",CurrentPrice,"at",CurrentTime)

    time.sleep(10)

你为什么不试试 yfinance 呢？：

pip install yfinance

import yfinance as yf
import time


def get_price() -> float:
    return yf.Ticker("NVDA").info.get("regularMarketPrice")


def run():
    for i in range(10):
        print(f"{i}: {get_price()}")
        time.sleep(10)


if __name__ == '__main__':
    run()
