00:00:00,660 --> 00:00:02,970
‫Instructor: Hi, now we will continue

2
00:00:02,970 --> 00:00:06,240
‫with the For Loops within the lecture as well.

3
00:00:06,240 --> 00:00:09,750
‫So, now we managed to get every element

4
00:00:09,750 --> 00:00:12,420
‫inside of that 'myNumbers' list

5
00:00:12,420 --> 00:00:16,140
‫and use those to create a new integer

6
00:00:16,140 --> 00:00:18,420
‫with the help of For Loops.

7
00:00:18,420 --> 00:00:22,950
‫So, I believe you now understood the importance of For Loops

8
00:00:22,950 --> 00:00:26,610
‫and the way that they work

9
00:00:26,610 --> 00:00:29,550
‫very efficiently with the list as well.

10
00:00:29,550 --> 00:00:32,220
‫So, let me show you something else.

11
00:00:32,220 --> 00:00:36,840
‫We can write the exact same For Loop like this.

12
00:00:36,840 --> 00:00:41,840
‫Int number and with a colon, 'myNumbers'.

13
00:00:42,270 --> 00:00:44,310
‫So, this thing

14
00:00:44,310 --> 00:00:48,660
‫is very often used with lists

15
00:00:48,660 --> 00:00:52,920
‫so that they came up with their own notation.

16
00:00:52,920 --> 00:00:55,290
‫So, how does this work?

17
00:00:55,290 --> 00:00:59,550
‫It means they take each element inside of 'myNumbers' list

18
00:01:00,870 --> 00:01:05,870
‫and assign it to a variable code number

19
00:01:06,090 --> 00:01:10,440
‫and do this as long as there is an element

20
00:01:10,440 --> 00:01:13,020
‫inside of 'myNumbers' list.

21
00:01:13,020 --> 00:01:15,750
‫So, this is essentially the same thing

22
00:01:15,750 --> 00:01:18,120
‫that we have written over here,

23
00:01:18,120 --> 00:01:22,800
‫but we are not bothering with indexes or something else.

24
00:01:22,800 --> 00:01:27,097
‫We're just writing 'int number : myNumbers'.

25
00:01:28,200 --> 00:01:30,450
‫So, this is what will happen.

26
00:01:30,450 --> 00:01:35,450
‫This is going to produce exactly the same result as before.

27
00:01:36,990 --> 00:01:40,800
‫And let me do the same thing over here so that you can see.

28
00:01:40,800 --> 00:01:44,370
‫I'm just gonna print out number.

29
00:01:44,370 --> 00:01:49,080
‫So, let me comment out this print outline

30
00:01:49,080 --> 00:01:51,330
‫and we will only see the numbers.

31
00:01:51,330 --> 00:01:54,630
‫As you can see, it takes elements one by one

32
00:01:54,630 --> 00:01:57,450
‫and it prints them out.

33
00:01:57,450 --> 00:02:01,290
‫So, this is very convenient. This is very easy to use.

34
00:02:01,290 --> 00:02:05,220
‫So, whenever you are decide to use For Loops

35
00:02:05,220 --> 00:02:09,150
‫with actually lists, you're more than welcome to use this.

36
00:02:09,150 --> 00:02:11,580
‫Of course, we can do the same thing over here as well,

37
00:02:11,580 --> 00:02:14,970
‫like divide it by three, multiply it by five,

38
00:02:14,970 --> 00:02:17,640
‫and you will get the same result.

39
00:02:17,640 --> 00:02:21,330
‫It's much more easy and it's much more convenient.

40
00:02:21,330 --> 00:02:23,580
‫So, maybe you can think something like that.

41
00:02:23,580 --> 00:02:27,660
‫Yeah, we can use For Loops with lists, we understood that.

42
00:02:27,660 --> 00:02:30,840
‫Can we use For Loops on their own?

43
00:02:30,840 --> 00:02:32,700
‫Yep, we can use them.

44
00:02:32,700 --> 00:02:35,640
‫It's not very practical though, I will tell you.

45
00:02:35,640 --> 00:02:38,880
‫I'm going to show you how you can use them.

46
00:02:38,880 --> 00:02:42,720
‫You can create a For Loop like with it, in the first place.

47
00:02:42,720 --> 00:02:46,110
‫You can create a new integer, for example.

48
00:02:46,110 --> 00:02:47,710
‫And you can just say

49
00:02:49,080 --> 00:02:52,080
‫as long as a is less than 10,

50
00:02:52,080 --> 00:02:54,330
‫I'm going to continue doing that.

51
00:02:54,330 --> 00:02:55,170
‫So, for example,

52
00:02:55,170 --> 00:02:58,140
‫let me create a new in integer called b

53
00:02:58,140 --> 00:03:01,860
‫and it's a multiplied by 10

54
00:03:01,860 --> 00:03:05,820
‫and you can actually print out that b

55
00:03:05,820 --> 00:03:08,280
‫in order to see the results as well.

56
00:03:08,280 --> 00:03:10,980
‫So, this will continue 10 times

57
00:03:10,980 --> 00:03:14,190
‫as long as a is less than 10.

58
00:03:14,190 --> 00:03:18,180
‫So, let me comment this out and round this.

59
00:03:18,180 --> 00:03:19,013
‫Here you go.

60
00:03:19,013 --> 00:03:21,990
‫Now we manage to print out

61
00:03:21,990 --> 00:03:24,720
‫0, 10, 20, 30,

62
00:03:24,720 --> 00:03:27,540
‫all the way up to the 90.

63
00:03:27,540 --> 00:03:30,060
‫Now you know how to work with loops

64
00:03:30,060 --> 00:03:33,030
‫and you know how For Loops actually work

65
00:03:33,030 --> 00:03:36,240
‫very well with lists.

66
00:03:36,240 --> 00:03:40,710
‫So, we are gonna see some other kind of loop as well,

67
00:03:40,710 --> 00:03:44,103
‫but that's what we're gonna do within the next lecture.
