Exercise

Create one holdout set

Your boss has asked you to create a simple random forest model on the tic_tac_toe dataset. She doesn't want you to spend much time selecting parameters; rather she wants to know how well the model will perform on future data. For future Tic-Tac-Toe games, it would be nice to know if your model can predict which player will win.

The dataset tic_tac_toe has been loaded for your use.

Note that in Python, =\ indicates the code was too long for one line and has been split across two lines.
