Data Manipulation Using Pandas and PyArrow

This workflow demonstrates the usage of python package pandas and pyarrow for data manipulation. The KNIME Table is read as pandas dataframe in the first branch of the workflow in the Python Script node, while it is read as a PyArrow table in the second branch in the Python Script node.

Further the data is normalised using the python commands of the respective python packages.
