我正在尝试从此网站https://www.programmableweb.com/apis/directory抓取每个API和类别的名称 并以这种格式打印出来
名称：Google Maps
类别：映射
由于某种原因，我的代码仅打印第一行。
我的代码
from bs4 import BeautifulSoup as bs
import requests
url = 'https://www.programmableweb.com/apis/directory'
response = requests.get(url)
data = response.text
soup = bs(data, 'html.parser')
info = soup.find_all('table',{'class':'views-table cols-4 table'})
for i in info:
name = soup.find('td',{'class':'views-field views-field-title col-md-3'}).text
category = soup.find('td',{'class':'views-field views-field-field-article-primary-category'}).text
print('name:',name, '\nCategory:', category)
如果您可以进一步帮助我，我想做的是：
答案 0 :(得分：1)
您没有遍历表中的行。您可以找到<table>标签的标签（只有1个，然后尝试遍历这些标签。您要做的是找到<tr>标签中的所有<table>标签，然后遍历<tr>标签。您还只是从soup对象中获取了第一个元素，而不是info对象中的
更简单的解决方案，因为它是您所追求的<table>标签，所以请使用pandas来抓取它（实际上是在幕后使用了beautifulsoup）。但这会为您完成所有艰苦的工作：
import pandas as pd
url = 'https://www.programmableweb.com/apis/directory'
table = pd.read_html(url)[0]
输出：
print (table.to_string())
