Write a function LeftShift(lst, x) in Python which accepts numbers in a list (lst) and all the elements of the list should be shifted to left according to the value of x.

Sample Input Data of the list lst = [20, 40, 60, 30, 10, 50, 90, 80, 45, 29] where x = 3

Output lst = [30, 10, 50, 90, 80, 45, 29, 20, 40, 60]

Answer

def LeftShift(lst, x):
    if x >= len(lst):
        x %= len(lst)
    shifted_lst = lst[x:] + lst[:x]
    return shifted_lst

lst = eval(input("Enter the list: "))
x = int(input("Enter the value of x: "))
result = LeftShift(lst, x)
print(result)

Output

Enter the list: [20, 40, 60, 30, 10, 50, 90, 80, 45, 29]
Enter the value of x: 3
[30, 10, 50, 90, 80, 45, 29, 20, 40, 60]



Enter the list: [55, 66, 77, 88, 99, 44, 33, 22, 11]
Enter the value of x: 4
[99, 44, 33, 22, 11, 55, 66, 77, 88]
