Working with data using python

[mlauber71]

@Alex_025 you might try without the .to_frame() part. Take a look at these examples:

AttributeError NoneType object has no attribute 'to_arrow_table'

@sirabelk3 I think you should make sure you have the latest version of the KNIME Python integration installed or a working Python installation of your own. Also you should check what type of data your code would produce. If you want to bring data back from Python to KNIME you would have to have an Arrow data table. Often you would have a Pandas data frame that you would then convert to Arrow. Maybe check out these examples.
