Boolean arrays

Additionally, NumPy handles indexing with Boolean logic:

First produce a Boolean array:

array_1 > 5array([[False, False],       [False, False],       [False,  True],       [ True,  True],       [ True,  True]], dtype=bool)

Place brackets around the Boolean array to filter by the Boolean array:

array_1[array_1 > 5]array([ 6,  7,  8,  9, 10])
