Obtenez de l'Attribut href du Lien de balise td BeautifulSoup Python

Je suis nouveau en Python et quelqu'un m'a suggéré d'utiliser Belle soupe pour la mise au Rebut et je me suis heurté à un problème pour récupérer l'attribut href d'une balise td Colonne 2 sur la base de l'année dans la colonne 4.

<table class="tableFile2" summary="Results">

<th width="10%" scope="col">Format</th>

<th width="10%" scope="col">Filing Date</th>
<th width="15%" scope="col">File/Film Number</th>
