Are you using Pipeline in Scikit-Learn?

If you are doing Machine Learning, you would have come across pipelines as they help you to make a better machine learning workflow which is easy to understand and reproducible. In case you are not aware of the pipelines you can refer awesome blogs from Rebecca Vickery "A Simple Guide to Scikit-learn Pipelines" and Saptashwa Bhattacharyya "A Simple Example of Pipeline in Machine Learning with Scikit-learn". Let's see how it can be done. To best demonstrate, I am going to use the Titanic dataset from OpenML here to walkthrough on how you can create a data pipeline. I am going to use a subset of features for the demo purposes here.
