"C2_W4_Lab_02_Tree_Ensemble": a code typo and a small issue

Course Q&A Machine Learning Specialization Advanced Learning Algorithms

Hello,

I think there’s a small code typo in “4.1 Decision Trees”: at the code block where decision_tree_model is set, the max_depth parameter should be 4, and not 3, right? This according to the analysis that identified 4 as the best value, and also according to the explanation in the text block right above it.

Also, in " 2. One-hot encoding using Pandas", we are told “First we will remove the binary variables, because one-hot encoding them would do nothing to them.”… but we are not, aren’t we? We’re one-hot encoding the variables ‘Sex’ and ‘ExerciseAngina’ too.

Thank you for the very interesting course!
