A perfect model
In this exercise you will reconstruct the lift curve of a perfect model. To do so, you need to construct perfect predictions.
Recall that the plot_lift_curve method requires two values for the predictions argument: the first argument for the target to be 0 and the second one for the target to be 1.

Introduction to Predictive Analytics in Python
Anleitung zur Übung
- Construct a list that has perfect predictions.
- The true values of the target are in
targets_test. Plot the lift curve using the perfect predictions.
