Welcome folks today in this example we will be swapping or interchanging first and last elements inside a list in python. All the full source code of the application is given below.

Get Started

In order to get started you need to create an app.py file and copy paste the following code

app.py

# Python3 program to swap first 
# and last element of a list 

# Swap function 
def swapList(newList): 
    size = len(newList) 
    
    # Swapping 
    temp = newList[0] 
    newList[0] = newList[size - 1] 
    newList[size - 1] = temp 
    
    return newList 
    
# Driver code 
newList = [12, 35, 9, 56, 24] 

print("The original list is \n")

print(newList)

print("\n")

print("The swapped list is ")

print(swapList(newList))

Now if you execute the above python script by typing the below command as shown below

python app.py

Now you can see that we have successfully swapped the first and last element inside the list
