Python Program to Print Array Elements Present on Even Position

Write a Python program to print array elements present on even position or even index position. In this python example, we used the list slicing that will increment by two to print the array elements present on an even position.

import numpy as np

arr = np.array([2, 4, 6, 8, 12, 14, 16, 18])

print('Printing the Array Elements at Even Position')
print(arr[1:len(arr):2])
Python Program to Print Array Elements Present on Even Position

Python program to print array elements present on even index position using a for loop. 

import numpy as np

arr = np.array([22, 44, 66, 88, 122, 144, 166, 188])

for i in range(1, len(arr), 2):
    print(arr[i], end = '  ')
44  88  144  188 

Python program to print array elements present at the even position using a while loop

import numpy as np

arr = np.array([11, 13, 15, 17, 19, 22, 39])

i = 1
while i < len(arr):
    print(arr[i], end = '  ')
    i = i + 2
13  17  22  

In this Python example, we used the if statement to find the even index position and print the array elements present on the even position. 

import numpy as np

evarrlist = []
evarrTot = int(input("Total Array Elements to enter = "))

for i in range(1, evarrTot + 1):
    evarrvalue = int(input("Please enter the %d Array Value = "  %i))
    evarrlist.append(evarrvalue)

evarr = np.array(evarrlist)

print('\nPrinting the Array Elements at Even Position')
for i in range(1, len(evarr), 2):
    print(evarr[i], end = '  ')

print('\nPrinting the Array Elements at Even Position')
for i in range(len(evarr)):
    if i % 2 != 0:
        print(evarr[i], end = '  ')
Total Array Elements to enter = 9
Please enter the 1 Array Value = 22
Please enter the 2 Array Value = 43
Please enter the 3 Array Value = 56
Please enter the 4 Array Value = 23
Please enter the 5 Array Value = 65
Please enter the 6 Array Value = 98
Please enter the 7 Array Value = 56
Please enter the 8 Array Value = 11
Please enter the 9 Array Value = 99
