This is a Python Program to swap the first and last value of a list.
The program takes a list and swaps the first and last value of the list.
1. Take the number of elements in the list and store it in a variable.
2. Accept the values into the list using a for loop and insert them into the list.
3. Using a temporary variable, switch the first and last element in the list.
4. Print the newly formed list.
5. Exit.
Here is source code of the Python Program to swap the first and last value of a list. The program output is also shown below.
a=[] n= int(input("Enter the number of elements in list:")) for x in range(0,n): element=int(input("Enter element" + str(x+1) + ":")) a.append(element) temp=a[0] a[0]=a[n-1] a[n-1]=temp print("New list is:") print(a)
1. User must enter the number of elements in the list and store it in a variable.
2. User must enter the values of elements into the list.
3. The append function obtains each element from the user and adds the same to the end of the list as many times as the number of elements taken.
4. A temporary variable is used to swap the first and last element in the list.
5. The newly formed list is printed.
Case 1: Enter the number of elements in list:4 Enter element1:23 Enter element2:45 Enter element3:67 Enter element4:89 New list is: [89, 45, 67, 23] Case 2: Enter the number of elements in list:3 Enter element1:56 Enter element2:34 Enter element3:78 New list is: [78, 34, 56]
