Name 'model' is not defined

Question

When I input this code

print(cross_val_score(model, X, y, cv=3)) 

An error comes back that reads name 'model' is not defined:

print(cross_val_score(model, X, y, cv=3))

If you're running your code cell-by-cell in an editor like Jupyter, you'll need to make sure that you run all the cells needed to define each element that you will be using in the line that you are trying to run.
