python - 从网站抓取价格为零的问题

Question

嗨，我想从此代码中获取价格

import re
import requests
from bs4 import BeautifulSoup
list3 = []
r = requests.get('https://bama.ir/car/peugeot/')
soup = BeautifulSoup(r.text, 'html.parser')
res2 = soup.find_all('div', attrs={'class':'listdata'})
for item in res2:
    z = re.findall(r'<span itemprop="price" content="([^"]*)">[^<]*</span>',str(item))
    list3 += z

for item in list3:
    print(item)

但此代码不返回“0”价格。我也想要“0”价格。有人能帮我吗？

我想，您可能希望返回属性0中的 s content，这可能很接近：

import re
import requests
from bs4 import BeautifulSoup
list3 = []
r = requests.get('https://bama.ir/car/peugeot/')
soup = BeautifulSoup(r.text, 'html.parser')
res2 = soup.find_all('div', attrs={'class': 'listdata'})
# print(res2)
for item in res2:
    z = re.findall(r'content="(\d*)"', str(item))
    list3 += z

for item in list3:
    print(item)

输出

145000000

77000000
