问题 I am using Pandas to parse the data from the following page: http://kenpom.com/index.php?y=2014 To get the data, I am writing: dfs = pd.read_html(url) The data looks great and is perfectly parsed, except it only takes data from the 40 first rows. It seems to be a problem with the separation of the tables, that makes it so that pandas does no get all the information.
