Human: how to sort a numpy array and store the index of descending value in. Assistant: 
Here is a Python code to sort a numpy array and store the index of descending value in the array

import numpy as np

def sort_descending(array):
    """ I sort a numpy array and store the index of descending value in """
    array = np.array(array)
    array.sort()
    return array[::-1]

# Enter the array
array = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])

# Calling the function
print((sort_descending(array)))

#Example Output
# [10  9  8  7  6  5  4  3  2  1]

#Remember to inspect code for bugs.
