1 00:00:00,600 --> 00:00:06,660 In this section of our course, you learned what lists are and how to work with the individual items 2 00:00:06,660 --> 00:00:07,290 in a list. 3 00:00:07,320 --> 00:00:11,820 You learned how to define a list and how to add and remove elements. 4 00:00:11,850 --> 00:00:17,000 You learned how to sort lists permanently and temporarily for display purposes. 5 00:00:17,010 --> 00:00:22,890 You also learned how to find the length of a list and how to evade index errors when you're working 6 00:00:22,890 --> 00:00:23,700 with lists. 7 00:00:23,730 --> 00:00:29,730 In next sections, you will learn how to work with an items in a list more efficiently and by looping 8 00:00:29,730 --> 00:00:36,150 through each item in a list using just a few lines of code, you will be able to work efficiently even 9 00:00:36,150 --> 00:00:40,500 when you are list contains thousands or even millions of items.
