Numerical Variables

Default Job

In this course, you will learn how to apply basic and more advanced feature engineering to tabular data with python, during this course,  we will see a range of different techniques and methods to handle many common cases within the data set, so in result, you will create great features so that your machine learning models can predict good results.

Feature Engineering with Python

## Challenge Definition

In this challenge, you are presented with a dataset of automobiles, in which many cars are listed with their price values, alongside some other features of each car, your goal from this challenge is to make some categorical encoding to some of the features like engine type, body style and so one.

You will be presented with a code execution widget below, in which you will find some steps to complete, complete all the steps, and then make sure to see at the end the solution to the challenge as I would approach it:
