WebNow we can use np.where to identify the array indices where a1d is greater than 5. You’ll notice the result is a tuple with a single array that contains index values 3 and greater. The first 3 elements in the array (a1d) with values of 1, 2, and 4 are not returned because the values of those elements are less than 5.
