00:00:00,150 --> 00:00:03,400
This is an exercise on Python set.

2
00:00:03,430 --> 00:00:07,040
First question is on ADD and update method.

3
00:00:08,050 --> 00:00:17,890
And you need to first create an empty set and then add elements of different data types to the set so

4
00:00:17,890 --> 00:00:27,490
you can add numbers strings lists etc. and you can use the ADD and update methods to add elements to

5
00:00:27,490 --> 00:00:38,390
the empty set and you also need to pay attention to the difference between the ADD and update methods.

6
00:00:38,390 --> 00:00:42,570
Second question is also on set methods.

7
00:00:42,590 --> 00:00:52,430
Consider these two sets set underscore land and set underscored water and you need to find out the unique

8
00:00:52,520 --> 00:00:56,090
elements from both the set.

9
00:00:56,230 --> 00:01:04,130
You also need to find out the elements and set land that are not existing in set water.

10
00:01:06,450 --> 00:01:14,190
So you can use the different methods that were discussed in class to answer this question so you can

11
00:01:14,250 --> 00:01:17,160
go ahead and answer these two questions.

12
00:01:17,160 --> 00:01:17,760
And good luck.
