Question

我需要以下代码的帮助：

import csv
import requests
from bs4 import BeautifulSoup
import datetime

filename = "imob_" + datetime.datetime.now().strftime("%Y-%m-%d-%H-%M")+".csv"
with open(filename, "w+") as f:
    writer = csv.writer(f)
    writer.writerow(["Localizare","Pret","Data"])

    for i in range(1,100):
        r = requests.get("https://www.imobiliare.ro/inchirieri-case-vile/brasov?pagina="+format(i))

        soup = BeautifulSoup(r.text, "html.parser")
        array_price= soup.find_all('div', class_='pret')
        array_desc=soup.find_all('h2', class_='titlu-anunt hidden-xs',text=True)
        for iterator in range(0,len(array_price)):
            localizare = array_desc[iterator].text.strip()
            pret = array_price[iterator].text.strip()

            writer.writerow([localizare, pret, datetime.datetime.now()])

输出为空。有人可以给我个建议吗？谢谢。

您遇到了几个问题：

首先，如注释中所述，类price不存在。您可以使用pret，但使用soup.find_all('span', class_="pret-mare")

更容易

第二array_desc=soup.find_all('h2', class_='titlu-anunt hidden-xs',text=True)返回空。我删除了text=True，它开始起作用。

import csv
import requests
from bs4 import BeautifulSoup
import datetime

filename = "imob_" + datetime.datetime.now().strftime("%Y-%m-%d-%H-%M")+".csv"
with open(filename, "w+") as f:
    writer = csv.writer(f)
    writer.writerow(["Localizare","Pret","Data"])

    for i in range(1,100):
        r = requests.get("https://www.imobiliare.ro/inchirieri-case-vile/brasov?pagina="+format(i))

        soup = BeautifulSoup(r.text, "html.parser")
        array_price = soup.find_all('span', class_="pret-mare")
        array_desc=soup.find_all('h2', class_='titlu-anunt hidden-xs')
        for iterator in range(0,len(array_price)):
            localizare = array_desc[iterator].text.strip()
            pret = array_price[iterator].text.strip()

            writer.writerow([localizare, pret, datetime.datetime.now()])

Web抓取python，empy输出
