About Python Lists Lists are a datatype you can use to store a collection of different pieces of information as a sequence under a single variable name … ..You can assign items to a list with Example : $ list_name = [item_1, item_2] Example : A list can also be empty: $ empty_list = [] Example : $ animals = ["cat", "dog", "lion", "tiger"];   print "The first " + animals[0] print "The second " + animals[1] print "The third " + animals[2] print "The fourth " + animals[3] Example : $ numbers = [5, 6, 7, 8] $ print numbers[0] + numbers[2] $ 12 Replace list value $ animals[2] = "zzz" … ..You can add items to the end of a list $ number.append(“9”) … ..List Slicing Sometimes, you only want to access a portion of a list. numb...
