Introduction
In Python, you can remove elements from a list using various methods. One such method is to remove elements from the end of the list. In this challenge, you will write a function that removes n elements from the end of a list.
Remove List Elements from the End
Write a function take_right(lst, n=1) that takes a list lst and an optional integer n as arguments and returns a new list with n elements removed from the end of the list. If n is not provided, the function should remove only the last element from the list.
To solve this problem, you can use slice notation to create a slice of the list with n elements taken from the end.
def take_right(itr, n = 1):
return itr[-n:]
take_right([1, 2, 3], 2) ## [2, 3]
take_right([1, 2, 3]) ## [3]
Summary
In this challenge, you learned how to remove elements from the end of a list in Python. You also learned how to use slice notation to create a slice of a list with n elements taken from the end.
