One hot encoding

In the video, you saw how the 'State' feature can be encoded numerically using the technique of one hot encoding:

Doing this manually would be quite tedious, especially when you have 50 states and over 3000 customers! Fortunately, pandas has a get_dummies() function which automatically applies one hot encoding over the selected feature.
