Replacing numpy array with max value [duplicate]

2024/11/18 9:36:38

I have an array,

a = np.array([[0,9,8],[5,6,4]])

how to replace the each array in axis 1 with the max value of its array?

excepting output- a = np.array([9,6]) where 9 is the max value in [0,9,8] and 6 is the max value in [5,6,4]

thanks

Answer

You should use

np.max(a, axis=1)
