Copy link

For future reference, line 13: return text.split('<tr class=\'athing\'>')[1].split("<a href")[1].split(">")[1].split("<")[0]

should be changed to:

return text.split('<tr class=\'athing\'')[1].split("<a href")[1].split(">")[1].split("<")[0]

The closing right angle bracket on the tr class causes an error because HN now uses an id for each tr in the style of:
<tr class='athing' id='13228490'>
