True or False: Ordinal Encoding

Try Ordinal Encoding Yourself!

Instructions:
Running a coding exercise for the first time could take a bit of time for everything to load. Be patient, it could take a few minutes.

When you see ____ in a coding exercise, replace it with what you assume to be the correct code. Run it and see if you obtain the desired output. Submit your code to validate if you were correct.

Make sure you remove the hash (#) symbol in the coding portions of this question. We have commented them so that the line won’t execute and you can test your code after each step.

We’ve seen our basketball dataset but have only used the features salary, weight and height. This time, let’s look at the country column and transform it.

Tasks:

Build an ordinal encoder that uses a dtype of int and name it ordinal_encoder.
Fit on X_column, transform it and save the results in an object named country_encoded.
