进口雅虎金融股票价格与beautifulsoup和要求 [英] import yahoo finance stock price with beautifulsoup and request

问题描述

因此，我有一个检查股价的脚本.雅虎改变了一些东西，现在我得到了％的变化，而不是股价.以下是原始脚本.运行它时，我得到的是"+0.70(+ 0.03％)"，而不是2477.83.我真正看到的唯一区别是:

So I have an script that check stock prices. Yahoo change something and now I get the % change rather than the stock price. Below is the original script. When I run it, I get "+0.70 (+0.03%)", rather than 2,477.83. The only difference I really see is:

data-reactid ="36"

data-reactid="36"

和

data-reactid ="35".

data-reactid="35".

当我更改为35时，它会失败. 36件作品，但只显示％变化.我要的是股价，而不是涨跌幅.

When I change to 35, it fails. 36 works but only show % change. I want stock price, not % change.

感谢您的帮助！

import urllib.request
from bs4 import BeautifulSoup


# S&P 500
page = urllib.request.urlopen("https://finance.yahoo.com/quote/%5EGSPC?p=^GSPC")
content = page.read().decode('utf-8')
soup = BeautifulSoup(content, 'html.parser')
valsp = soup.find("span", {"data-reactid": "36"}).decode_contents(formatter="html")
print(valsp)

推荐答案

有不止一个span元素，其data-reactid ="35"属性，因此请通过class属性选择所需的一个.

There is more than one span element with the attribute data-reactid = "35" so select the one you want by the class attribute.

import urllib.request
from bs4 import BeautifulSoup

# S&P 500
page = urllib.request.urlopen("https://finance.yahoo.com/quote/%5EGSPC?p=^GSPC")
content = page.read().decode('utf-8')
soup = BeautifulSoup(content, 'html.parser')
# print (soup)
valsp = soup.find("span", {"data-reactid": "35", "class" : "Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)"}).decode_contents(formatter="html")
print(valsp)

输出:

2,477.83

唯一的变化是代码中的这一行:

The only change is this line in your code:

valsp = soup.find("span", {"data-reactid":"35"}).decode_contents(formatter="html")

到

valsp = soup.find("span", {"data-reactid": "35", "class" : "Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)"}).decode_contents(formatter="html")
