Scale the Features

In this challenge, you need to scale the features using StandardScaler. The data is a good old Penguins dataset (encoded and with no missing values).


              
12345

            
import pandas as pd

df = pd.read_csv('https://codefinity-content-media.s3.eu-west-1.amazonaws.com/a65bbc96-309e-4df9-a790-a1eb8c815a1c/penguins_imputed_encoded.csv')

print(df)
copy

Here is a little reminder of StandardScaler class.

Task
test

  1. Import the StandardScaler class
  2. Initialize a StandardScaler object.
  3. Fit and transform the X using that object.
