Python resultset
WebResultSet: The actual data asked for in the query when using a fetch method such as .fetchall () on a ResultProxy. This separation between the ResultSet and ResultProxy allows us to fetch as much or as little data as we desire. Once we have a ResultSet, we can use Python to access all the data within it by column name and by list style indexes. This gives you a result set – i.e. all the elements that match the class. You can either iterate over them or, if you know you only have one dataFrame, you can use find instead. From your code it seems the latter is what you need, to deal with the immediate problem: table = soup.find(class_='dataframe')
