1
00:00:00,570 --> 00:00:01,020
All right.

2
00:00:01,030 --> 00:00:02,400
It's exercise time.

3
00:00:02,410 --> 00:00:06,190
Let's combine everything that we've learned into this challenge.

4
00:00:06,250 --> 00:00:13,570
What I want you to do is to create a function called the highest even and this function is going to

5
00:00:13,570 --> 00:00:15,940
take a list data.

6
00:00:16,780 --> 00:00:20,190
And this function for now we'll just pass.

7
00:00:20,290 --> 00:00:25,800
But I want you to fill in this part with whatever you think is going to allow us to achieve this.

8
00:00:25,840 --> 00:00:38,500
If I do print highest even and I give it a list of let's say 1 2 3 4 8 I want the highest even to be

9
00:00:38,500 --> 00:00:40,060
printed in this list.

10
00:00:40,060 --> 00:00:42,140
And actually let's do 10 here.

11
00:00:42,220 --> 00:00:48,240
So the highest even number in this list is 10 just for fun.

12
00:00:48,240 --> 00:00:50,370
That's at eleven as well.

13
00:00:50,430 --> 00:00:58,200
So the answer should be printed here as 10 so based on everything you've learned so far.

14
00:00:58,210 --> 00:01:01,720
Try to fill this part so that you create your own function.

15
00:01:01,730 --> 00:01:04,420
Hi Stephen pause the video here.

16
00:01:04,420 --> 00:01:08,660
Give it a try otherwise I'm going to go with the answer.

17
00:01:08,700 --> 00:01:10,290
So what I want to do here.

18
00:01:10,350 --> 00:01:17,640
Let's think about this is I want to make sure that first of all we only consider the numbers that are

19
00:01:17,850 --> 00:01:27,890
even in here so maybe what I'll do is create a new list called evens and events is going to be an empty

20
00:01:27,890 --> 00:01:36,180
list for now but I'm going to populate this with all of the even numbers so I'm going to remove three

21
00:01:36,180 --> 00:01:40,090
and 11 from this so let's do that.

22
00:01:40,090 --> 00:01:53,500
I'm going to say for item in ally if item modulo 2 equals zero which means it's going to be even then

23
00:01:53,500 --> 00:01:59,110
I'm going to even append the item.

24
00:01:59,110 --> 00:02:03,120
So I'm going to add it to this new list.

25
00:02:03,350 --> 00:02:12,850
And then finally in here once we have the Evens list I want to find the highest number.

26
00:02:12,890 --> 00:02:20,390
Now you can do this manually and go through it one by one or Python comes with a nice function called

27
00:02:20,600 --> 00:02:21,410
Max.

28
00:02:21,410 --> 00:02:28,400
And as you can see we give it an interval and it'll tell us what the max number is in our case we can

29
00:02:28,400 --> 00:02:34,680
just give it evens and remember we want to return something from this function.

30
00:02:34,800 --> 00:02:37,620
That is what is the highest number.

31
00:02:37,650 --> 00:02:41,750
Well we want to return whatever the max of the Evens is.

32
00:02:42,030 --> 00:02:50,220
If I run this I get 10 awesome looks like it's working.

33
00:02:50,320 --> 00:02:56,230
Now some of you may have gotten tricked and tried to return inside of the four.

34
00:02:56,770 --> 00:03:05,830
But if we do this remember that this still works but we actually return from the function when we hit

35
00:03:05,860 --> 00:03:07,210
our first item.

36
00:03:07,300 --> 00:03:17,000
If we had another item let's say two in here and I click Run we get two and why is that.

37
00:03:17,000 --> 00:03:25,210
Because I'm returning when we loop the first time through our item which will be two is to an even number.

38
00:03:25,220 --> 00:03:25,760
Yes it is.

39
00:03:25,760 --> 00:03:34,050
So we're going to append and then we're finally returning Max evens which only contains the item two.

40
00:03:34,100 --> 00:03:39,410
So you want to make sure here that the indentation really matters and if you're returning something

41
00:03:39,650 --> 00:03:45,410
from inside a loop you want to make sure that that's your intended behavior.

42
00:03:45,530 --> 00:03:49,630
You usually want to loop through something and then return.

43
00:03:49,730 --> 00:03:55,450
So make sure you don't prematurely exit the loop nice and simple.

44
00:03:55,450 --> 00:03:59,250
Remember your answer may be different than mine.

45
00:03:59,290 --> 00:04:06,820
There are many ways to go about this but hopefully by practicing this you have a better idea of functions.

46
00:04:06,820 --> 00:04:14,330
We now have a great utility function highest even that we can use all over our program.

47
00:04:14,390 --> 00:04:17,690
Good job getting this far and I'll see you in the next one up.
