用Python写一个爬虫爬取58同城租房信息

好的，我们可以使用 Python 中的 requests 库和 BeautifulSoup 库来实现爬取 58 同城租房信息的功能。具体步骤如下：

1. 导入所需库：

import requests
from bs4 import BeautifulSoup

2. 构造 URL 并发送请求：

url = 'https://hz.58.com/chuzu/pn1/'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299'
}
response = requests.get(url, headers=headers)

3. 解析 HTML 并提取数据：

soup = BeautifulSoup(response.text, 'html.parser')
house_list = soup.select('.list > li')
for house in house_list:
    title = house.select('.des > h2 > a')[0].text.strip()
    price = house.select('.money > b')[0].text.strip()
    house_type = house.select('.room > p')[0].text.strip()
    location = house.select('.add > a')[0].text.strip()
    print(title, price, house_type, location)

完整代码如下：

import requests
from bs4 import BeautifulSoup

url = 'https://hz.58.com/chuzu/pn1/'
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Edge/16.16299'
}
response = requests.get(url, headers=headers)

soup = BeautifulSoup(response.text, 'html.parser')
house_list = soup.select('.list > li')
for house in house_list:
    title = house.select('.des > h2 > a')[0].text.strip()
    price = house.select('.money > b')[0].text.strip()
    house_type = house.select('.room > p')[0].text.strip()
    location = house.select('.add > a')[0].text.strip()
    print(title, price, house_type, location)

这样就完成了爬取 58 同城租房信息的功能。需要注意的是，爬虫涉及到的数据抓取和使用需要遵守相关法律法规，如有违反后果自负。
