how to access the last element of a list in python

1# To get the last element in a list you use -1 as position
2bikes = ['trek', 'redline', 'giant']
3bikes[-1]
4# Output:
5# 'giant'

1MyList=["Black","Blue","Red","Green"]
2print(MyList[-1])

1mylist = [0, 1, 2]
2mylist[-1] = 3 # sets last element
3print(myList[-1]) # prints Last element

1l = [1, 2, 3]
2l[-1]

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

1>>> some_list = [1, 2, 3]
2>>> some_list[-1] = 5 # Set the last element
3>>> some_list[-2] = 3 # Set the second to last element
4>>> some_list
