When it is required to swap the first and last values of a list using Python, a method can be defined, that uses a simple sorting technique to sort the values.
Below is a demonstration of the same −
def list_swapping(my_list): size_of_list = len(my_list) temp = my_list my_list = my_list[size_of_list - 1] my_list[size_of_list - 1] = temp return my_list my_list = [34, 21, 56, 78, 93, 20, 11, 9] print("The list is :") print(my_list) print("The function to swap the first and last elements is swapped") print(list_swapping(my_list))
The list is : [34, 21, 56, 78, 93, 20, 11, 9] The function to swap the first and last elements is swapped [9, 21, 56, 78, 93, 20, 11, 34]
A method named ‘list_swapping’ is defined.
It takes a list as a parameter.
The first and the last elements of the list are swapped.
The resultant list is returned as output.
Outside the function, a list is defined and displayed on the console.
The method is called bypassing this list as a parameter.
The output is displayed on the console.
