尝试设置User-Agent标题时，请求从雅虎的页面：

import requests
from bs4 import BeautifulSoup

ticker = input("Enter the ticker symbol: ")

url = f"https://finance.yahoo.com/quote/{ticker}/history?p={ticker}"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0"
}

response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, "html.parser")
table = soup.find("table", {"class": "W(100%) M(0)"})
rows = table.tbody.find_all("tr")

stock_prices = []
for row in rows:
    cells = row.find_all("td")
    if cells and len(cells) > 3:
        try:
            stock_prices.append(float(cells[4].text.replace(",", "")))
        except ValueError:
            print("Error parsing stock price")

print(stock_prices)

图纸（例如AAPL）：
