How to organize array filtering in Python numpy?

Question

Python

Good evening.
Tell me which direction to go.
For example, there is an array like:

a = np.array()

in numpy it seems like there was a thing that allows you to filter by a given parameter
(column 1 = 1) so that the output is:
[0, 1, 2]
[110, 1, 113]

Answer 1

a[ a[:, 1] == 1 ]
