這是我的代碼
from tkinter.ttk import Separator
import requests

url='https://www.yellowpages.ca/search/si/2/hvac services/Ontario ON'
headers = {'user-agent' : 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36' , 'Accept-Language': 'en-US, en;q=0.5'}
r = requests.get(url, headers = headers)
soup = BeautifulSoup(r.content, 'html.parser')
articles = soup.find_all('div', class_ ='listing__content__wrapper')
for item in articles:
company_name = item.find('a', class_ ="listing__name--link listing__link jsListingName").get_text(strip=True, separator='\n')
print(company_name)
#print(len(articles))
問題：1. print(len(articles))= 34 個串列計數 OK
2. print(company_name)= 只有一個 company_name 顯示不是所有 company_name 串列
我該如何為所有 company_name 串列做些什么？
uj5u.com熱心網友回復：
這只是一個小小的調整 - 檢查你的列印命令的 indet 它應該在你的 for 回圈中而不是在外面運行：
for item in articles:
company_name = item.find('a', class_ ="listing__name--link listing__link jsListingName").get_text(strip=True, separator='\n')
print(company_name)
