import numpy as np
num = np.arange(36)
arr1 = np.reshape(num, [4, 9])
print("Original array:")
print(arr1)
result = arr1.sum(axis=0)
print("\nSum of all columns:")
print(result)Sample Output:
Original array: [[ 0 1 2 3 4 5 6 7 8] [ 9 10 11 12 13 14 15 16 17] [18 19 20 21 22 23 24 25 26] [27 28 29 30 31 32 33 34 35]] Sum of all columns: [54 58 62 66 70 74 78 82 86]
