Filtering with masks

In the last lesson, you sorted trees from smallest to largest. Now, you'll use fancy indexing to return the row of data representing the largest tree in tree_census. You'll also examine other trees located on the same block as the largest tree: are they also large?

numpy is loaded as np, and the tree_census array is available. As a reminder, the tree_census columns in order refer to a tree's ID, its block ID, its trunk diameter, and its stump diameter.

  • Using Boolean indexing, create an array, largest_tree_data, which contains the row of data on the largest tree in tree_census corresponding to the tree with a diameter of 51.
