Stepping into 2D

Now assume that your research requires you to take an admittedly unrepresentative sample of trunk diameters, which are located in the third column of tree_census. Getting just a selection of trunk diameters can be done with NumPy's slicing and stepping functionality.

numpy is loaded as np, and the tree_census 2D array is available.
