Porting Knime one to many node into python?

Background: I’m working on some Kaggle challenges

Problem: The one to many node in Knime labels columns differently than the one hot encoder in Kaggle’s Python/Jupyter notebooks.

As a result, the models I built and trained in Knime don’t work correctly.

What’s the best way to address this issue? I’m slowly picking up python so the Knime environment is easier to work in for me.
