Python Program to Print Array Elements in Reverse Order

Write a Python program to print array elements in reverse order.  In this example, the list slicing with negative value prints the numpy array elements in reverse order.

import numpy as np

arr = np.array([15, 25, 35, 45, 55, 65, 75])

print('Printing the Array Elements in Reverse')
print(arr[::-1])

print('\nPrinting the Array Elements')
print(arr)
Python Program to Print Array Elements in Reverse Order

In this Python program, the for loop iterates array elements from last to first based on the index position and print the array items in reverse order.

import numpy as np

arr = np.array([15, 25, 35, 45, 55, 65, 75])

for i in range(len(arr) - 1, -1, -1):
    print(arr[i], end = '  ')
75  65  55  45  35  25  15

This Python program helps to print array elements in reverse order using a while loop.

import numpy as np

arr = np.array([22, 44, 66, 77, 89, 11, 19])
    
i = len(arr) - 1
while i >= 0:
    print(arr[i], end = '  ')
    i = i - 1
19  11  89  77  66  44  22

This example allows entering the Numpy Array elements and printing them in reverse order.

import numpy as np

arrlist1 = []
arrTot = int(input("Total Number of Array Elements to enter = "))

for i in range(1, arrTot + 1):
    arrvalue = int(input("Please enter the %d Array Value = "  %i))
    arrlist1.append(arrvalue)

arr = np.array(arrlist1)

print('Printing the Array Elements in Reverse')
for i in range(len(arr) - 1, -1, -1):
    print(arr[i], end = '  ')
Total Number of Array Elements to enter = 9
Please enter the 1 Array Value = 21
Please enter the 2 Array Value = 34
Please enter the 3 Array Value = 65
Please enter the 4 Array Value = 78
Please enter the 5 Array Value = 98
Please enter the 6 Array Value = 34
Please enter the 7 Array Value = 65
Please enter the 8 Array Value = 87
Please enter the 9 Array Value = 99
Printing the Array Elements in Reverse
99  87  65  34  98  78  65  34  21
