6. Write a Python Numpy program to calculate weight average of the given array in the following output.

The output is:

Expected Answer:
Initial array: [1 2 3 4 5]
Weights:    [2 3 4 5 6]

Weighted average of the array: 3.5

Sample Answer:

import numpy as np

a = np.arange(1, 6)
print("Initial array:", a)

weights = np.arange(2, 7)
print("\nWeights:      ", weights)

r1 = np.average(a, weights=weights)

print("\nWeighted average of the array:", r1)
