Python Swaps the First and Last Elements of a List

Python3 Examples

Define a list and swap the first and last elements of the list.

For example:

Before swapping: [1, 2, 3]
After swapping: [3, 2, 1]

Example 1

def swapList(newList): 
    size = len(newList) 

    temp = newList[0] 
    newList[0] = newList[size - 1] 
    newList[size - 1] = temp 

    return newList 

newList = [1, 2, 3] 

print(swapList(newList))

The output of the above example is:

[3, 2, 1]

Example 2

def swapList(newList): 

    newList[0], newList[-1] = newList[-1], newList[0] 

    return newList 

newList = [1, 2, 3] 
print(swapList(newList))

The output of the above example is:

[3, 2, 1]

Example 3

def swapList(list): 

    get = list[-1], list[0] 

    list[0], list[-1] = get 

    return list

newList = [1, 2, 3] 
print(swapList(newList))

The output of the above example is:

[3, 2, 1]
