1 00:00:00,000 --> 00:00:04,909 [MUSIC] 2 00:00:04,909 --> 00:00:07,720 Welcome to stage two of Python Sequences. 3 00:00:07,720 --> 00:00:09,790 Now that you've learned how to iterate through sequences, 4 00:00:09,790 --> 00:00:12,310 let's talk about sequence operations. 5 00:00:12,310 --> 00:00:15,110 Sequence operations are things you can do with sequences 6 00:00:15,110 --> 00:00:19,110 like slicing them into smaller sequences, determining one's length, or 7 00:00:19,110 --> 00:00:23,210 learning which element in the sequence is the highest or lowest value. 8 00:00:23,210 --> 00:00:25,390 There are also operations to determine whether or 9 00:00:25,390 --> 00:00:30,880 not a given element is in the sequence or how many times that element appears. 10 00:00:30,880 --> 00:00:35,060 There are even ways to combine sequences through addition and multiplication. 11 00:00:35,060 --> 00:00:38,180 This course will be specifically covering operations that are common to 12 00:00:38,180 --> 00:00:41,400 all Python sequences, both mutable and immutable. 13 00:00:42,950 --> 00:00:46,280 At the end of this stage, you'll be provided with a reference instruction step 14 00:00:46,280 --> 00:00:49,200 that summarizes the different operations you're about to learn. 15 00:00:49,200 --> 00:00:52,180 And some others that aren't discussed in the following videos. 16 00:00:52,180 --> 00:00:54,930 Bookmark that page for easy access later. 17 00:00:54,930 --> 00:00:56,860 We'll begin in the next video with slices.
