python - How to ignore a th tag while parsing html table? -

hello quite new parsing html tables python , beautifulsoup4. has been going until have run weird table uses 'th' tag midway through table, causing parse quit , throw 'index out of range' error. i've tried searching , google no avail. question how ignore or strip rogue 'th' tag while parsing table?

here code have far:

from mechanize import browser bs4 import beautifulsoup mech = browser() url = 'https://www.moscone.com/site/do/event/list' page = mech.open(url) html = page.read() soup = beautifulsoup(html) table = soup.find('table', { 'id' : 'list' }) row in table.findall('tr')[3:]: col = row.findall('td') date = col[0].string name = col[1].string location = col[2].string record = (name, date, location) final = ','.join(record) print(final)

here little snippet of html causes error

<td> convention </td> </tr> <tr> <th class="title" colspan="4"> mon dec 01 00:00:00 pst 2014 </th> </tr> <tr> <td> 12/06/14 - 12/09/14 </td>

i want info above , below rogue 'th' indicates start of new month on table

you can check if th in row , parse content if not, this:

for row in table.findall('tr')[3:]: # create sure th not in row if not row.find_all('th'): col = row.findall('td') date = col[0].string name = col[1].string location = col[2].string record = (name, date, location) final = ','.join(record) print(final)

this results provided url without indexerror:
