Output Data Tables with Python Script

This workflow shows how to write a Pandas DataFrame or a PyArrow Table as a KNIME table using the Python Script node. After writing the file, it can be used for other processes further down the pipeline as needed.

1 output table 2 output tables Writing Pandas DataFrame 1 output table 2 output tables Writing PyArrow Table 1) 1 output table with Pandas- A Pandas DataFrame is passed as a outputtable with knio.output_tables[0]2) 2 output tables with Pandas- Similar to above example, but with an additionaloutput port.- Add the second output port to the Python Scriptnode by clicking on the three dots- The second output table is passed withknio.output_tables[1] 1) 1 output table with PyArrow- A PyArrow table is passed as a output table withknio.output_tables[0]2) 2 output tables with PyArrow- Similar to above example, but with an additionaloutput port.- Add the second output port to the Python Scriptnode by clicking on the three dots- The second output table is passed withknio.output_tables[1] Adopting Python Bundled Packages : Download and open this workflow to auto-install requirements and execute the Python scripts. This workflow uses a node from KNIMEPython Integration, which installs Python and a number of pre-defined packages on your system. Supported on KNIME Analytics Platform4.7 or higher.
