Answer 1

Answer:-❤

➡️numpy.where() accepts a condition and 2 optional arrays i.e. returns a bool numpy array boolArr, containing TRUE of each element that is equal to 15, for other elements it contains False i.e. Then it will return a tuple of arrays (one for each axis) containing indices where value was TRUE in given bool numpy array

We can get the indices of N maximum values in a NumPy array using the below code:

import numpy as np

arr = np.array([1, 3, 2, 4, 5])

print(arr.argsort()[-3:][::-1])
