Execute Python breaks Colum if text hasta commas

Hi I need some help I'm doing some crawling with Python (already tried with RM but I didn't get what I wanted in an easy way)
The last column of DF returns a big chunk of text that describes the product. for some reason when Execute Python creates the DataSet it creates new lines and erases the data that was sent on the DF. I tried writing the info from inside Python Execute and the outcome is a file with 1 row and 5 columns as expected.

Here is the process I'm using.

    Great!!! It works and yes it seems to be a bug. 
    I'll need to make some changes since sometimes the crawling may not have that attribute and the number of rows maybe dynamic but your workaround works like a charm.

    @MarcoBarradas can you pls be more specific about the bug? I'd like to push it internally but need more detail. I'm not a Python coder... :wink:

    Hi @sgenzer the bug is that RM changes the Data Frame when it converts it to a RM Dataset. This happens when one of the attributes has a lot of text. In my example the Dataframe has a ágape of 1 example with 5 attributes. But once Execute Python ends it returns 3 example with 5 attributes and it only returne information of the last attribute. The one that had a lot of text
