Question

不知道出了什么问题，但是python代码在尝试执行网络抓取时会输出一个空白文件。代码正在成功执行，但是输出文件中没有任何数据。以下是详细信息。以下代码有什么问题？标题和价格只是我要提取的两个字段。

import requests
import os

from bs4 import BeautifulSoup
URL = 'https://sa.aqar.fm/%D8%A3%D8%B1%D8%A7%D8%B6%D9%8A- 
%D9%84%D9%84%D8%A8%D9%8A%D8%B9/1'
myfile = "Landsv11245.csv"
if os.path.isfile(myfile):

    f = open(myfile, "w", encoding='utf-8')

        f.writelines("title" + "," + "price" + "," + "size" + "," + "bed" + "," + "bath" + "\n")

print (URL)
res = requests.get(URL)
soup = BeautifulSoup(res.text, 'lxml')   
f = open(myfile, "a", encoding='utf-8')
for items in soup.select(".content [id^='single-id-']"):
        title = items.select_one("h4 a").text
        price = items.select_one(".prices").text
        f.write(title +","+ price.replace(",", "") + "\n")
f.close()

f.writelines（“标题” +“，” +“价格” +“，” +“大小” +“，” +“床” +“，” +“浴” +“ \ n”）其他：
f =打开（myfile，“ w”，编码=“ utf-8”） f.writelines（“标题” +“，” +“价格” +“，” +“ \ n”）

 URL = 'https://sa.aqar.fm/%D8%A3%D8%B1%D8%A7%D8%B6%D9%8A-

 print (URL)
 res = requests.get(URL)
 soup = BeautifulSoup(res.text, 'lxml')   
 f = open(myfile, "a", encoding='utf-8')
 for items in soup.select(".content [id^='single-id-']"):
 title = items.select_one("h4 a").text
 price = items.select_one(".prices").text
 f.write(title +","+ price.replace(",", "") + "\n")
 f.close()

Python输出文件为空-Web抓取
