Question

我正在尝试编写一个非常简单的python / beautiful汤脚本

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup 
my_url = 'https://www.travelok.com/listings/sid.1?last_region=&searchFormText=camping'
uclient = uReq(my_url)
page_html = uclient.read()
uclient.close()
filename = "oklahoma_state_parks.csv"
f = open(filename,"w")
headers = "park_name, park_phone, \n"
f.write (headers)
page_soup = soup(page_html, 'html.parser')
containers = page_soup.findAll("article", {"class":"search-result"})

这是确保其在此处工作的测试代码。

parkinfo_name_test = containers[0].h2.text
parkinfo_phone_test = containers[0].address.div.text

parkinfo_name_test_2 = containers[2].h2.text
parkinfo_phone_test_2 = containers[2].address.div.text

如果我现在运行代码（此处的所有内容），则工作正常。我可以打印（parkinfo_name_test）并得到第一个结果。但是当我尝试循环它时-它失败了。当我尝试使用代码我收到一条错误消息：

for container in containers:
    parkinfo_name = container[0].h2.text
    parkinfo_phone = container[0].address.div.text 

    print ("parkinfo_name: " + parkinfo_name)
    print ("parkinfo_phone " + parkinfo_phone)

    f.write (parkinfo_name + "," + parkinfo_phone + "\n")
    f.close ()

这是我收到的错误消息：
追溯（最近一次通话）：文件“ oklahoma_state_parks.py”，第43行，位于parkinfo_name = container [0] .h2.text
文件“ C：\ Users \ Myname \ AppData \ Local \ Programs \ Python \ Python37-32 \ lib \ site-packages \ beautifulsoup4-4.6.1-py3.7.egg \ bs4 \ element.py”，第1071行，位于__getitem__return self.attrs [key]中 KeyError：0

Answer 1

问题似乎在这里：

for container in containers:
    parkinfo_name = container[0].h2.text

尝试通过这种方式进行操作：

for container in containers:
    parkinfo_name = container.h2.text
    parkinfo_phone = container.address.div.text 

    print ("parkinfo_name: " + parkinfo_name)
    print ("parkinfo_phone " + parkinfo_phone)

    f.write (parkinfo_name + "," + parkinfo_phone + "\n")
    f.close ()

Python“返回self.attrs [key]”错误
