Counting the elements of an array and creating another array in Python

Question

I have an array y. I want to create another array x which is based on the length of y. I present the current and expected outputs.

import numpy as np

y=np.array([60.        , 57.71689783, 43.92696073, 41.27856221, 52.87672123,
        46.75800742, 40.36532134, 42.10047899, 44.65755342, 52.69407306,
        48.49316507, 53.78, 55.0        ])

x=np.array([len(y)])

The current output is

array([13])

The expected output is

array([1,2,3,4,5,6,7,8,9,10,11,12,13])
