title: Power BI: Multiple tables as output of Python in Power Query
body: <p>I am running a Python script in the Power Query editor of Power BI to transform and work with my data.  After these computations, I want to return the dataset and another table to the Power Query editor.  Am I correct that this second table needs to be a Pandas Dataframe?</p>
  
  <p>Only when converting the second table from a numpy.ndarray to a pandas.DataFrame, does Power BI recognize it as tabular output <a href="https://i.stack.imgur.com/pgUHR.png" rel="nofollow noreferrer">(result after script)</a>.  Is this the expected behaviour?  Can other Python objects than a Pandas Dataframe be passed down to Power BI?</p>
