You can use slice notation to get the last n elements of a list in Python. Simple use the slicing syntax [ ] by passing a -n: as an argument to it.
Python last n elements of the list
A simple example code getting the last two elements of ["a", "b", "c"] results in ["b", "c"].
a_list = ["a", "b", "c"]
# Retrieve last 2 elements of list
last_n = a_list[-2:]
print(last_n)
# last 2 elements of list
test_list = [4, 5, 2, 6, 7, 8, 10]
res = test_list[-2:]
print(res)Output:
Using islice() + reversed()
from itertools import islice
test_list = [4, 5, 2, 6, 7, 8, 10]
N = 5
res = list(islice(reversed(test_list), 0, N))
res.reverse()
print("The last N elements of list are : " + str(res))Output: The last N elements of the list are : [2, 6, 7, 8, 10]
Note: if the list has fewer than n elements, this approach will return the entire list. If you want to handle such cases differently, you may want to add a check for the length of the list.
