Python: Shift last element to first position and first element to last position in a list

Python List: Exercise - 189 with Solution

Write a Python program to shift last element to first position and first element to last position in a given list.

Sample Solution:

Python Code:

def shift_first_last(lst):
    x = lst.pop(0)
    y = lst.pop()
    lst.insert(0, y)
    lst.insert(len(lst), x)
    return lst

nums = [1,2,3,4,5,6,7]
print("Original list:")
print(nums)
print("Shift last element to first position and first element to last position of the said list:")
print(shift_first_last(nums))

chars = ['s','d','f','d','s','s','d','f']
print("\nOriginal list:")
print(chars)
print("Shift last element to first position and first element to last position of the said list:")
print(shift_first_last(chars))

Sample Output:

Original list:
[1, 2, 3, 4, 5, 6, 7]
Shift last element to first position and first element to last position of the said list:
[7, 2, 3, 4, 5, 6, 1]

Original list:
['s', 'd', 'f', 'd', 's', 's', 'd', 'f']
Shift last element to first position and first element to last position of the said list:
['f', 'd', 'f', 'd', 's', 's', 'd', 's']
