Python BeautifulSoup刮削比特币价格问题

我对python还是新手，尤其是BeautifulSoup。我已经读了几天这方面的东西，玩了一堆不同的代码，得到了混合的结果。然而，第页是我想要的比特币价格。价格位于：

16569.40美元

也就是说，我想让脚本只打印值所在的行。我当前的代码打印整个页面，但它看起来不是很好，因为它打印了很多数据。有人能帮我改进代码吗

import requests
from BeautifulSoup import BeautifulSoup

url = 'https://coinmarketcap.com/currencies/bitcoin/'
response = requests.get(url)
html = response.content

soup = BeautifulSoup(html)
div = soup.find('text-large2', attrs={'class': 'stripe'})

for row in soup.findAll('div'):
    for cell in row.findAll('tr'):
        print cell.text

这是我运行代码后得到的输出的一小部分。它看起来不太好看，也不可读

9HitBTCBCH/BTC$305,554,000$15601.901.52%Recently

试试这个：

import requests
from BeautifulSoup import BeautifulSoup

url = 'https://coinmarketcap.com/currencies/bitcoin/'
response = requests.get(url)
html = response.content

soup = BeautifulSoup(html)
div = soup.find("div", {"class" : "col-xs-6 col-sm-8 col-md-4 text-left" 
}).find("span", {"class" : "text-large2"})

for i in div:
    print i

这是我打印的16051.20

稍后编辑：如果你把上面的代码放在一个函数中并循环它，它会不断更新。我现在得到了不同的值。

这很有效。但我认为您使用的是较旧版本的BeautifulSoup，请尝试在命令提示符或PowerShell中安装bs4

import requests
from bs4 import BeautifulSoup

url = 'https://coinmarketcap.com/currencies/bitcoin/'
response = requests.get(url)
html = response.text

soup = BeautifulSoup(html, 'html.parser')

value = soup.find('span', {'class': 'text-large2'})
print(''.join(value.stripped_strings))
