Input:

test_list = [3, 6, 7, 8, 9, 2, 1, 5]

Output:

[2,6,8,1,3,5,7,9]

Solve:

# initializing list

test_list = [3, 6, 7, 8, 9, 2, 1, 5]

 

# printing original list

print("The original list : " + str(test_list))

 

# using naive method

# Separating odd and even index elements

odd_i = []

even_i = []

for i in range(0, len(test_list)):

    if i % 2:

        even_i.append(test_list[i])

    else :

        odd_i.append(test_list[i])

 

res = odd_i + even_i

 

# print result

print("Separated odd and even index list: " + str(res))
