00:00:00,420 --> 00:00:01,050
Welcome back.

2
00:00:01,590 --> 00:00:05,860
Let's try and do an exercise to tie everything that we've learned up until now.

3
00:00:05,880 --> 00:00:09,190
Together, we're going to create a password checker.

4
00:00:10,020 --> 00:00:15,750
Now, while we want to do is to create some sort of an input that we're going to ask.

5
00:00:15,900 --> 00:00:22,560
So we're going to use the input function and here we're going to ask for a username.

6
00:00:23,160 --> 00:00:25,350
Then we're going to ask for another input.

7
00:00:25,950 --> 00:00:28,710
It's going to be the password.

8
00:00:30,400 --> 00:00:35,710
And then at the end, with the input we want to print.

9
00:00:36,940 --> 00:00:46,870
Something, the lines of password, and then we'll have maybe the actual password in here and it will

10
00:00:46,870 --> 00:00:50,930
say is another variable here long.

11
00:00:51,550 --> 00:00:57,130
So what we want to do is the password and then maybe the password.

12
00:01:00,070 --> 00:01:07,540
So that let's say we printed our username Jayjay, and then we give it a password of secret.

13
00:01:08,110 --> 00:01:11,770
Well, we should print the password.

14
00:01:12,520 --> 00:01:20,410
Secret is one, two, three, four, five, six letters long.

15
00:01:21,820 --> 00:01:30,850
Now, obviously, we don't want to show or display the password, maybe for security reasons, so we

16
00:01:30,850 --> 00:01:36,250
want to convert the secret to one, two, three, four, five, six, two stars.

17
00:01:37,650 --> 00:01:42,780
So your task is to convert these two inputs.

18
00:01:44,070 --> 00:01:50,700
And, you know, let's also do a greeting where we say the username here, so we're going to say, hey,

19
00:01:51,150 --> 00:01:51,690
J.J..

20
00:01:53,610 --> 00:01:54,630
Your password.

21
00:01:56,110 --> 00:02:04,690
Which will be marked in a star is six letters long now, one neat trick here that you haven't learned

22
00:02:04,690 --> 00:02:09,790
yet and you might want to use here is this they can do with strings.

23
00:02:10,660 --> 00:02:13,480
I can go Star Times.

24
00:02:15,540 --> 00:02:23,310
Make sure that the star is a string, multiply it by 10, and if I print this out.

25
00:02:28,110 --> 00:02:36,000
I get 10 stars, so you may want to use this functionality when we're doing this.

26
00:02:37,220 --> 00:02:43,070
All right, pause the video, give it a go, if you can remember, the goal is to print the username

27
00:02:43,670 --> 00:02:49,640
and have the password blocked with how many characters the password is.

28
00:02:51,510 --> 00:02:54,960
All right, pause the video, if not, I'm going to get going with the answer.

29
00:02:55,960 --> 00:03:00,630
So the first thing we're going to try and do is I'm going to create two inputs.

30
00:03:01,390 --> 00:03:08,320
So the first one, I'm going to get the user name, going to assign it to the variable user name and

31
00:03:08,320 --> 00:03:13,360
it's going to say, what is your username?

32
00:03:14,910 --> 00:03:17,310
Then the second one will be the password.

33
00:03:18,910 --> 00:03:23,040
And the password, well, we'll say, what is your password?

34
00:03:25,370 --> 00:03:30,950
And although this is a simple example, this is something that you will see with other big websites

35
00:03:30,950 --> 00:03:34,880
like Instagram or maybe Netflix when you're logging in.

36
00:03:36,590 --> 00:03:43,160
So now that I've stored this information into a variable, I can use it right, I can print and we'll

37
00:03:43,160 --> 00:03:45,540
do an F string to make our lives easier.

38
00:03:46,190 --> 00:03:47,420
So I've added the F here.

39
00:03:47,750 --> 00:03:49,910
And what we'll do is this will say.

40
00:03:51,560 --> 00:03:52,250
Username.

41
00:03:53,970 --> 00:03:55,860
Your password.

42
00:03:56,940 --> 00:03:59,670
And we'll add the password here.

43
00:04:01,920 --> 00:04:04,860
Is and then we'll add.

44
00:04:05,880 --> 00:04:07,770
Another variable here.

45
00:04:09,350 --> 00:04:11,850
Which is the password length.

46
00:04:12,740 --> 00:04:14,690
So how are we going to calculate that?

47
00:04:15,650 --> 00:04:16,950
Well, let's try something here.

48
00:04:17,120 --> 00:04:23,210
Let's see if I can use the length function and in here, do password.

49
00:04:24,320 --> 00:04:25,270
Let's see what happens here.

50
00:04:27,850 --> 00:04:28,810
What is my username?

51
00:04:29,350 --> 00:04:30,580
Let's go with Andre.

52
00:04:32,370 --> 00:04:36,330
What is my password, let's just type in secret here.

53
00:04:37,790 --> 00:04:39,710
And I get Andre your password.

54
00:04:40,690 --> 00:04:49,870
Well, I can't speak English properly, my password secret is six well, six what let's write six letters

55
00:04:50,620 --> 00:04:50,980
long.

56
00:04:52,890 --> 00:04:53,270
Awesome.

57
00:04:53,790 --> 00:05:03,480
So this is working because with an F string, I can create or add a python expression in here using

58
00:05:03,480 --> 00:05:07,270
the length password, but there's an issue here, right?

59
00:05:07,290 --> 00:05:09,210
We don't want to actually print out secret.

60
00:05:09,220 --> 00:05:11,190
We want to print it out in the star form.

61
00:05:11,940 --> 00:05:15,780
And this is a good discussion topping on readability of your code.

62
00:05:16,170 --> 00:05:21,420
Now, this is a simple example, but we can make this code a little bit cleaner.

63
00:05:22,060 --> 00:05:27,720
For example, we can break things down so that we'll have password.

64
00:05:31,290 --> 00:05:32,400
Will be lenth.

65
00:05:33,670 --> 00:05:36,160
Password, so we're calculating the length.

66
00:05:36,190 --> 00:05:42,030
So this is going to store six or whatever the input of our password is and it's nice and descriptive,

67
00:05:42,040 --> 00:05:43,970
it's easy for other developers to understand.

68
00:05:44,560 --> 00:05:45,760
And then in here.

69
00:05:46,680 --> 00:05:58,530
I can also have hidden password and this hidden password will be the password lenth, and we're going

70
00:05:58,530 --> 00:06:00,720
to use that star.

71
00:06:02,050 --> 00:06:05,110
String and multiply it by the password length.

72
00:06:05,560 --> 00:06:07,390
Let's make this a little bit bigger.

73
00:06:09,310 --> 00:06:17,260
So that now our code can be understood well in an easier fashion, so we have the password lenth, so

74
00:06:17,260 --> 00:06:24,250
we're going to say username your password password, but we want to make sure that it's the hidden password.

75
00:06:24,260 --> 00:06:25,720
So we'll copy this over here.

76
00:06:27,780 --> 00:06:34,150
So username your password, we're going to print out a hidden password is and then we're going to copy

77
00:06:34,200 --> 00:06:35,010
password lenth.

78
00:06:36,090 --> 00:06:39,030
Now, I argue that this reads better.

79
00:06:40,150 --> 00:06:48,070
Because each line is doing something simple and then finally we're printing the output, and although

80
00:06:48,100 --> 00:06:55,210
this is a small, simple example, this idea of readability and making and writing code that makes sense

81
00:06:56,230 --> 00:06:57,550
is an important concept.

82
00:06:58,270 --> 00:06:59,380
So let's see if this works.

83
00:06:59,620 --> 00:07:03,040
I'm going to click run my username, Andre.

84
00:07:03,700 --> 00:07:07,360
This time around, my password is going to be super secret.

85
00:07:09,070 --> 00:07:09,640
And look at that.

86
00:07:09,880 --> 00:07:11,560
Andre, your password did.

87
00:07:11,570 --> 00:07:14,290
It is 11 letters long.

88
00:07:15,570 --> 00:07:16,960
Good job getting this far.

89
00:07:17,520 --> 00:07:18,480
Hopefully you got that.

90
00:07:19,140 --> 00:07:20,520
I'll see you in the next video.
