Hello KNIME Community, I am working on a KNIME workflow where I want to manipulate tabular data (from exel file) in a python script node BUT without using additional libraries like pandas. The help()-function on the input table returns that the tables are of type ArrowSourceTable and I don’t see where you can access elements. My goal is to compare data manipulations in the python script of pandas operations on the pandas dataframe with raw python string operations on the ArrowSourceTable or some other table. I want to know if working with pandas is necessary for my use case and if I can only rely on raw python. Does someone has experience with these ArrowSourceTables? And does someone know if there are efficiency advantages using raw python over pandas? Any help is truly appreciated. Alex

@makaveli the Python integration comes with support for pandas dataframes and arrow.

The data exchange between knime and Python will be handled via arrow:
