美丽的汤变量跨班

想知道如果你可以帮助一些网络报废我试图做。美丽的汤变量跨班

下面是我想从中获取数据的span类。问题是跨度类中存在不同数据点的随机数。

我知道部分“价格-VAL”是所有迭代相同的，但我不能工作，如何获取数据时，搜索只是这一点。

<span class="price-val_196775436 odd-val ib right"> 
    2.47 
    </span>

到目前为止我的代码

url ="http://www.sportsbet.com.au/betting/american-football" 
    r = requests.get(url) 
    soup = BeautifulSoup(r.content) 
    g_data = soup.find_all("div", {"class": "accordion-body"}) 



    for item in g_data: 
      A = item.find('span', {'class': 'team-name ib'}).text 
      B = item.find('span', {'class': 'price-val_196775436 odd-val ib right'}).text

错误我得到

Traceback (most recent call last): 
    File "C:\Users\James\Desktop\NFLsportsbet.py", line 23, in <module> 
    B = item.find('span', {'class': 'price-val'}).text 
AttributeError: 'NoneType' object has no attribute 'text'

谢谢，这有助于堆@SIslam – Jimmyn

使用解析库例如lxml，并可能需要使用正则表达式或氯氟

import requests,re 
from bs4 import BeautifulSoup 

url ="http://www.sportsbet.com.au/betting/american-football" 
r = requests.get(url) 
soup = BeautifulSoup(r.content,'lxml') 
g_data = soup.find_all("div", {"class": "accordion-body"}) 



for items in g_data: 
    print items.find('span', {'class': 'team-name ib'}).text 
    print items.find('span', {'class': lambda L: L and L.startswith('price-val_')}).text 
    #print items.find('span', {'class': re.compile('price-val_*')}).text #or regex like this

它打印
