Python slicing

sample_list = [0,1,2,3,4,5,6,7,8,9]
# First item
sample_list[0]
# Last item
sample_list[-1]
# First 3 items
sample_list[:3]
# Last 3 items
sample_list[-3:]
# A copy of the list
sample_list[:]
# A copy of the list without first item
sample_list[1:]
# A copy of the list without last item
sample_list[:-1]
