# Python Program to Sort Array in Descending Order

Write a Python Program to sort Numpy Array items in Descending order. First, the Numpy sort function (orarr.sort()) sorts the array items in ascending order. Next, we sliced the array using negative values to reverse the array (descarr = orarr[::-1]), which becomes descending.

```# Sort Array Descending

import numpy as np

orarr = np.array([22, 98, 77, 88, 35, 15, 122, 91])
print("***Sorting Numpy Array in Descending Order***")
print("Original Array             = ", orarr)

orarr.sort()
descarr = orarr[::-1]
print("Array in Descending Order  = ", descarr)```

Sort Python Numpy Array items in Descending order output

``````***Sorting Numpy Array in Descending Order***
Original Array             =  [ 22  98  77  88  35  15 122  91]
Array in Descending Order  =  [122  98  91  88  77  35  22  15]``````

## Python Program to Sort Array in Descending Order using the For Loop.

In this Python example, we used the Nested for loop range to sort the numpy array items in Descending order. Within the loop, the if statement (if (dearr[i] < dearr[j])) checks each item is less than other array items and assigns them to the temp variable.

```# Sort Array Descending

import numpy as np

dearr = np.array([11, 46, 22, 89, 77, 98, 55, 181, 65])
print("***Sorting Numpy Array in Descending Order***")
print("Original Array             = ", dearr)

length = len(dearr)

for i in range(length):
for j in range(i + 1, length):
if (dearr[i] < dearr[j]):
temp = dearr[i]
dearr[i] = dearr[j]
dearr[j] = temp

print("Array in Descending Order  = ", dearr)```

Sort Python Numpy Array items in Descending order using a for loop output

``````***Sorting Numpy Array in Descending Order***
Original Array             =  [ 11  46  22  89  77  98  55 181  65]
Array in Descending Order  =  [181  98  89  77  65  55  46  22  11]``````

In this Python Numpy Array example, we created a function (arrayDescending(dearr)) that sorts the array elements in Descending order.

```# Sort Array Descending

import numpy as np

def arrayDescending(dearr):
for i in range(len(dearr)):
for j in range(i + 1, len(dearr)):
if (dearr[i] < dearr[j]):
temp = dearr[i]
dearr[i] = dearr[j]
dearr[j] = temp

dearr = np.array([64, 36, 77, 55, 88, 95, 44, 91, 21])
print("***Sorting Numpy Array in Descending Order***")
print("Original Array             = ", dearr)

arrayDescending(dearr)
print("Array in Descending Order  = ", dearr)```
