python last item in list

1l = [1,2,3,4,5]
2last = l[len(l)-1]

1a = [1, 2, 3, 4]
2print(a[-1])
3#prints: 4
4
5print(a[-2])
6#prints: 3

1some_list = [1, 2, 3]
2some_list[-1]
3print(some_list)
4#Output = 3

1number_list = [1, 2, 3]
2print(number_list[-1]) #Gives 3
3
4number_list[-1] = 5 # Set the last element
5print(number_list[-1]) #Gives 5
6
7number_list[-2] = 3 # Set the second to last element

9[1, 3, 5]

1# Use an Index of -1
2l = [1,2,3,4]
3print(l[-1])
4# Returns 4

1some_list = [1,2,3]
2some_list[-1] is the shortest and most Pythonic.
