Python: Start with a list of integers, keep every other element in place and otherwise sort the list

Python Programming Puzzles: Exercise-92 with Solution

Write a Python program to start with a list of integers, keep every other element in place and otherwise sort the list.

Input: 
[2, 5, 6, 3, 1, 4, 34]
Output:
[1, 5, 2, 3, 6, 4, 34]

Input:
[8, 0, 7, 2, 9, 4, 1, 2, 8, 3]
Output:
[1, 0, 7, 2, 8, 4, 8, 2, 9, 3]

Sample Solution:

Python Code:

def test(nums):
    li = nums.copy()    
    for i in range(len(li)):
        if i % 2 == 0: 
            for j in range(i+2, len(li), 2):
                if li[j] < li[i]:
                    swap(li, i, j)
    
    return li
def swap(li, i, j):
    temp = li[i]
    li[i] = li[j]
    li[j] = temp
nums = [2, 5, 6, 3, 1, 4, 34]
print("Original list (triple) of lists:")
print(nums)
print("In the said list, keep every other element in place and otherwise sort the list.:")
print(test(nums))
nums = [8, 0, 7, 2, 9, 4, 1, 2, 8, 3]
print("\nOriginal list (triple) of lists:")
print(nums)
print("In the said list, keep every other element in place and otherwise sort the list.:")
print(test(nums))

Sample Output:

Original list (triple) of lists:
[2, 5, 6, 3, 1, 4, 34]
In the said list, keep every other element in place and otherwise sort the list.:
[1, 5, 2, 3, 6, 4, 34]

Original list (triple) of lists:
[8, 0, 7, 2, 9, 4, 1, 2, 8, 3]
In the said list, keep every other element in place and otherwise sort the list.:
[1, 0, 7, 2, 8, 4, 8, 2, 9, 3]
