import numpy as np
x = np.arange(5)
print("\nOriginal array:")
print(x)
weights = np.arange(1, 6)
r1 = np.average(x, weights=weights)
r2 = (x*(weights/weights.sum())).sum()
assert np.allclose(r1, r2)
print("\nWeighted average of the said array:")
print(r1)

Sample Output:

Original array:
[0 1 2 3 4]

Weighted average of the said array:
2.6666666666666665
