如何从网络抓取的混合字符串中分离价格（数字）

Question

im试图编写返回我给定网址价格的代码，代码：

from bs4 import BeautifulSoup
import time
from smtplib import SMTP
import pandas as pd
import numpy as np
import requests



URL='https://www.bigbasket.com/pd/10000200/fresho-tomato-hybrid-1-kg/?nc=cl-prod-list&t_pg=&t_p=&t_s=cl-prod-list&t_pos=1&t_ch=desktop'




headers = {"User-Agent":'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36 OPR/65.0.3467.78'}


page= requests.get(URL, headers = headers)
soup = BeautifulSoup(page.content,'html.parser')


div=soup.find(id="price")
print(div)

输出：

<div id="price"><table><tbody class="_6eiYL" id="10000200"><tr class="_23Nyv"><td>MRP: </td><td class="_2ifWF">Rs <!-- -->37.50</td></tr><tr class="_157dw"><td> <!-- -->Price:</td><td class="IyLvo" data-qa="productPrice">Rs <!-- -->30</td></tr><tr class="_21awm"><td>You Save: </td><td class="IyLvo">20%</td></tr><tr><td></td> <td>(Inclusive of all taxes)</td></tr></tbody></table></div>

我想获得价格（即37.50）作为我的输出，而不是我得到的输出。

from bs4 import BeautifulSoup
import requests
import re

headers = {"User-Agent":'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36 OPR/65.0.3467.78'}

page= requests.get(URL, headers = headers)
soup = BeautifulSoup(page.content,'html.parser')

item=soup.find('div',id="price").find_next('td', text=re.compile('MRP:')).find_next('td').contents
print(item[-1])
