Question

import requests
from bs4 import BeautifulSoup

res = requests.get('https://www.amcham.com.au/web/Events/Web/Events/Upcoming_Events.aspx?hkey=6f098583-ca3d-4a6f-87de-cd4f13d50b11')
soup = BeautifulSoup(res.text,"lxml")

event_title = soup.find('span', {'class': 'eventTitle'})
event_location = soup.find('span', {'class': 'city'})
event_place =  soup.find('span', {'class': 'place'})
event_date =  soup.find('span', {'class': 'eventDate'})


print(event_title.text)
print(event_place.text,event_location.text)
print(event_date.text)

我使用此代码从网站上提取即将发生的事件标题，位置，日期信息。

我期待在整个系列中循环关注网站上的活动并提取活动标题，地点，地点，日期信息，有人可以帮我一样吗？

Answer 1

您需要使用findAll获取每个的完整列表：

event_title = [i.text for i in soup.findAll('span', {'class': 'eventTitle'})]
event_location = [i.text for i in soup.findAll('span', {'class': 'city'})]
event_place = [i.text for i in soup.findAll('span', {'class': 'place'})]
event_date =  [i.text for i in soup.findAll('span', {'class': 'eventDate'})]

Answer 2

另一种方法可能如下所示：

import requests
from bs4 import BeautifulSoup

res = requests.get('https://www.amcham.com.au/web/Events/Web/Events/Upcoming_Events.aspx?hkey=6f098583-ca3d-4a6f-87de-cd4f13d50b11')
soup = BeautifulSoup(res.text,"lxml")

for item in soup.find_all(class_=["rgRow","rgAltRow"]):
    event_title = item.find(class_='eventTitle').text
    event_location = item.find(class_='city').text
    event_place =  item.find(class_='place').text
    event_date =  item.find(class_='eventDate').text
    print(event_title,event_location,event_place,event_date)

Answer 3

使用单select个查询的优化解决方案：

import requests, pprint
import collections
from bs4 import BeautifulSoup

res = requests.get('https://www.amcham.com.au/web/Events/Web/Events/Upcoming_Events.aspx?hkey=6f098583-ca3d-4a6f-87de-cd4f13d50b11')
soup = BeautifulSoup(res.text,"lxml")

event_data = collections.defaultdict(list)
for el in soup.select('span.eventTitle, span.city, span.place, span.eventDate'):
    event_data[el['class'][0]].append(el.text)

pprint.pprint(dict(event_data))

漂亮输出：
