# 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]
