Question

当我在循环中的变量末尾添加.text时，它引发了AttributeError。我将其删除，它会打印出所有标签以及信息。我不知道为什么它不断抛出AttributeError。

感谢任何帮助，T.T

我尝试过：

biz_name = result.find('span', attrs={'itemprop':'name'}).text

和

biz_name = result.find('span', attrs={'itemprop':'name'}).text[1:-1]

这是结果的一个单元格：

<span itemprop="name">Efrain Jimenez Jr. General Contractor Inc.</span>

和脚本：

import requests
from bs4 import BeautifulSoup
import pandas as pd
import csv

r = requests.get('https://www.yellowpages.com/search?search_terms=remodeling&geo_location_terms=New+York%2C+NY')

soup = BeautifulSoup(r.text, 'html.parser')

results = soup.find_all('div', attrs={'class':'info'})

records = []

for result in results:
    biz_name = result.find('span', attrs={'itemprop':'name'})
    biz_phone = result.find('div', attrs={'itemprop':'telephone'})
    biz_address = result.find('span', attrs={'itemprop':'streetAddress'})
    biz_city = result.find('span', attrs={'itemprop':'addressLocality'})
    biz_zip = result.find('span', attrs={'itemprop':'postalCode'})
    records.append((biz_name, biz_phone, biz_address, biz_city, biz_zip))

df = pd.DataFrame(records, columns=['biz_name', 'biz_phone', 'biz_address', 'biz_city', 'biz_zip'])

df.to_csv('Yp_Remodel.csv', index=False, encoding='utf-8')

也许不是最理想的答案，但似乎在某些情况下，某些值是“ None”，因此，如果尝试访问其文本，则会出现错误。试试这个，对我有用。

import requests
from bs4 import BeautifulSoup
import pandas as pd
import csv

r = requests.get('https://www.yellowpages.com/search?search_terms=remodeling&geo_location_terms=New+York%2C+NY')
soup = BeautifulSoup(r.text, 'html.parser')
results = soup.find_all('div', attrs={'class':'info'})

records = []

for result in results:
    biz_name = result.find('span', attrs={'itemprop':'name'}).text if result.find('span', attrs={'itemprop':'name'}) is not None else ''
    biz_phone = result.find('div', attrs={'itemprop':'telephone'}).text if result.find('span', attrs={'itemprop':'telephone'}) is not None else ''
    biz_address = result.find('span', attrs={'itemprop':'streetAddress'}).text if result.find('span', attrs={'itemprop':'streetAddress'}) is not None else ''
    biz_city = result.find('span', attrs={'itemprop':'addressLocality'}).text if result.find('span', attrs={'itemprop':'addressLocality'}) is not None else ''
    biz_zip = result.find('span', attrs={'itemprop':'postalCode'}).text if result.find('span', attrs={'itemprop':'postalCode'}) is not None else ''
    records.append((biz_name, biz_phone, biz_address, biz_city, biz_zip))


df = pd.DataFrame(records, columns=['biz_name', 'biz_phone', 'biz_address', 'biz_city', 'biz_zip'])

df.to_csv('Yp_Remodel.csv', index=False, encoding='utf-8')

AttributeError：'NoneType'对象没有属性'text'-元组
