从多个标签中获取数据 BeautifulSoup/Python

Question

I am trying to get as much data as possible from this site including the title, time and the event per time.

For example for the Aniversary Awards Ceremony, it should print that title, 8:30, and the name of event that happens at 8:30.

The tags after the title, (such as the time) start to repeat/change multiple times not allowing to pull with accuracy. Is there a better way to approach this? Pull all data as accurate to the site?

Thanks

import requests
from bs4 import BeautifulSoup
import pandas as pd
productlinks=[]

url='https://www.sitcancer.org/2020/program/annual-meeting-schedule-2020'
r=requests.get(url)
soup=BeautifulSoup(r.content,'html.parser')
productlist=soup.find_all('div',class_='HtmlContent')
for section in productlist:
    title=section.find('span',style="font-family: helvetica; color: #ef4136;")
    if title is not None:
        title=title.text
    else:
        title='No'
    print(title)

This should get you close enough to what you need, and you can take from there:

from bs4 import Tag, NavigableString
tabs = soup.select('div.HtmlContent table[style="height: 740px; width: 100%;"] tbody')
for t in tabs[0]:    
    if not isinstance(t, NavigableString ) and len(t.text.strip())>0:        
        if 'Session' in t.text:
            print(t.text)
        else:
            if t.select_one('h3') is not None:
                print(t.text.strip())
            else:                
                for w in t.select('td span strong'):
                    print(w.text.strip())
                for f in t.select('span[style="color: #000000;"]'):
                    print(f.text.strip())  

    

Output:

9 a.m.–3:15 p.m. EST*
