00:00:13,360 --> 00:00:19,680
Hello to all of my students, and now we're just going to see some examples regarding your state's statements,

2
00:00:19,690 --> 00:00:27,190
the basic part, and I was always a fan of starting easy and then like increasing the speed.

3
00:00:27,460 --> 00:00:31,540
So to understand all the basics, you always have to start from basics, right?

4
00:00:31,570 --> 00:00:35,850
You can just go from zero to 60 in one second.

5
00:00:35,860 --> 00:00:45,010
And I'm always a believer of getting the things breaking down into small pieces and go further in steps.

6
00:00:45,170 --> 00:00:45,460
All right.

7
00:00:46,060 --> 00:00:49,510
So once you open your project, just create a new file.

8
00:00:49,690 --> 00:00:55,060
You can call it if statements basics.

9
00:00:56,170 --> 00:01:02,500
And right now, I'm just going to show you some examples from the previous lecture so it could sink

10
00:01:02,680 --> 00:01:04,180
in your in your mind.

11
00:01:04,330 --> 00:01:09,980
And I think we'll get the hang of if statements more easily after seeing these examples.

12
00:01:10,660 --> 00:01:11,080
All right.

13
00:01:11,090 --> 00:01:17,140
So first of all, let's just create here a comment for us in the future, as always.

14
00:01:17,360 --> 00:01:20,930
And let's head off with a simple example.

15
00:01:20,950 --> 00:01:30,760
So, first of all, let's create a salary variable integer that set is as a thousand and let's return

16
00:01:30,760 --> 00:01:31,400
each statement.

17
00:01:31,420 --> 00:01:40,060
So I just want to say that if salary is bigger, right, because this mathematical sign points towards

18
00:01:40,060 --> 00:01:49,210
salary, this means salaries bigger, then five thousand, then two that I want to print.

19
00:01:50,650 --> 00:01:54,330
My salary is too low.

20
00:01:54,380 --> 00:01:58,120
I need to change my job, so sort of a joke.

21
00:01:58,660 --> 00:01:59,230
All right.

22
00:02:00,700 --> 00:02:01,090
All right.

23
00:02:01,090 --> 00:02:09,970
And then right here else, as you recall from the previous lecture, like if this is the output of that

24
00:02:09,970 --> 00:02:11,630
statement is true.

25
00:02:12,010 --> 00:02:14,140
So this would be executed.

26
00:02:14,140 --> 00:02:16,200
Everything under the earth would be executed.

27
00:02:16,210 --> 00:02:23,380
But if it's not true, meaning it's false, the house is the default exit point, meaning that if this

28
00:02:23,390 --> 00:02:27,000
won't be ran, so everything under else would run.

29
00:02:27,100 --> 00:02:27,420
All right.

30
00:02:27,970 --> 00:02:33,190
And right here, I want to say salary is above 5000.

31
00:02:34,630 --> 00:02:35,860
It's OK for now.

32
00:02:35,900 --> 00:02:36,160
Right.

33
00:02:36,670 --> 00:02:43,350
So and this statement we can see here a true value because our salary is eight thousand.

34
00:02:43,360 --> 00:02:51,880
And the statement says the salary is above five thousand and this is actually above above five thousand.

35
00:02:51,890 --> 00:02:54,850
So this we expect this one to print.

36
00:02:55,210 --> 00:02:57,360
Let's run it and make sure that this happens.

37
00:02:58,150 --> 00:02:58,640
Great.

38
00:02:58,720 --> 00:02:59,770
So as you can see.

39
00:03:00,160 --> 00:03:05,950
Yeah, the statement, the print under the if condition was printed out.

40
00:03:06,190 --> 00:03:08,080
And let's just try to play with it a little bit.

41
00:03:09,110 --> 00:03:15,980
Let's just set here four thousand nine hundred ninety nine and let's run it now.

42
00:03:17,800 --> 00:03:18,360
All right.

43
00:03:18,550 --> 00:03:24,130
As you can see accordingly, as we change the value of the salary, which is now smaller or smaller

44
00:03:24,130 --> 00:03:25,360
than five thousand.

45
00:03:25,690 --> 00:03:32,290
Now, it's it did not print this print out, went to alse, which is the point.

46
00:03:32,290 --> 00:03:41,260
And after that, the cold exits the if completely meaning whether this printout out or this this out

47
00:03:41,440 --> 00:03:47,430
after one of them is executed, the code goes down to here and sorry.

48
00:03:47,440 --> 00:03:47,920
Here.

49
00:03:48,970 --> 00:03:49,330
Yeah.

50
00:03:51,600 --> 00:03:58,070
Just want to show you, like going here, yeah, and going down here, exit the if statements completely.

51
00:03:58,080 --> 00:03:59,790
All right, so it runs only one time.

52
00:04:00,450 --> 00:04:04,350
But let's see what happens if we put 5000.

53
00:04:04,350 --> 00:04:04,820
Exactly.

54
00:04:04,830 --> 00:04:08,280
So 5000 is 5000, bigger than 5000.

55
00:04:09,360 --> 00:04:10,150
Anyone knows.

56
00:04:10,680 --> 00:04:12,540
So the answer is.

57
00:04:16,100 --> 00:04:20,810
Yep, the answer is this one false.

58
00:04:21,020 --> 00:04:27,940
All right, so why because 5000 is not bigger than 5000, it equals the five thousand.

59
00:04:27,950 --> 00:04:35,090
But if we put an equals mark right here like this, this means we can do we can put two operators here,

60
00:04:35,210 --> 00:04:37,640
pool math, two math operators here.

61
00:04:37,940 --> 00:04:46,220
We're saying here, if it's equal, if it's bigger, if salaries bigger or equals 5000, then execute

62
00:04:46,220 --> 00:04:47,130
this line right here.

63
00:04:47,510 --> 00:04:48,560
So let's run it.

64
00:04:49,700 --> 00:04:50,340
Whoa.

65
00:04:50,360 --> 00:04:50,780
Yet.

66
00:04:50,810 --> 00:04:56,840
So we can see that this one was printed out because we added the equals mark right here, meaning it's

67
00:04:56,840 --> 00:04:59,690
bigger or equals than 5000.

68
00:04:59,700 --> 00:05:00,970
So this statement is true.

69
00:05:01,880 --> 00:05:03,720
But once we removed this one.

70
00:05:03,980 --> 00:05:05,870
So this statement is false.

71
00:05:06,140 --> 00:05:08,360
And once it's false, this will not run.

72
00:05:08,690 --> 00:05:11,900
The default exit point will be executed, which is the yellow.

73
00:05:12,680 --> 00:05:16,430
So as you just saw, I did some experiments here.

74
00:05:16,430 --> 00:05:18,770
And programming is all about experience.

75
00:05:18,770 --> 00:05:20,990
My friends, you always need to experiment.

76
00:05:20,990 --> 00:05:25,040
And once you see, like a statement that you're not really familiar with and you don't really know what

77
00:05:25,040 --> 00:05:26,930
it does, just try to play with it.

78
00:05:26,930 --> 00:05:31,400
Just try to change the values right here and see what will happen that way.

79
00:05:31,850 --> 00:05:37,240
According to the output, you can learn about the body of the statement that we're learning.

80
00:05:37,460 --> 00:05:37,750
All right.

81
00:05:37,760 --> 00:05:42,070
So just changing the values here made me learn a lot about the statement.

82
00:05:42,940 --> 00:05:45,320
Let's go over to the next statement.

83
00:05:46,250 --> 00:05:48,890
I'm just going to put age 30 here.

84
00:05:48,890 --> 00:05:59,050
And if age is bigger than 50, then I want to present you are above 50.

85
00:06:01,490 --> 00:06:05,120
You are a senior developer for sure.

86
00:06:06,080 --> 00:06:06,470
Yep.

87
00:06:06,740 --> 00:06:07,430
Just a joke.

88
00:06:07,440 --> 00:06:07,700
Right?

89
00:06:08,930 --> 00:06:10,940
Then we can put an L if here.

90
00:06:11,150 --> 00:06:18,260
And if you recall from the previous video, we used one example for if else only and one example for

91
00:06:18,440 --> 00:06:24,770
if ayliffe example, once we have several options, several conditions.

92
00:06:24,770 --> 00:06:40,700
So if age bigger than 40 and right now we want to present you, your age is bigger than 40, you are

93
00:06:41,540 --> 00:06:44,600
a developer for some time.

94
00:06:46,200 --> 00:06:47,100
But if not.

95
00:06:48,320 --> 00:06:51,920
It's better late than never.

96
00:06:52,040 --> 00:06:52,580
All right.

97
00:06:54,190 --> 00:06:59,000
I really believe in this sentence because I always believed in challenging yourself, not doesn't matter

98
00:06:59,000 --> 00:07:01,460
what age you are, and it's never too late.

99
00:07:01,640 --> 00:07:02,000
All right.

100
00:07:03,350 --> 00:07:05,210
So this one was the second statement.

101
00:07:05,210 --> 00:07:10,700
And let's add another one, a much bigger than thirty five.

102
00:07:15,270 --> 00:07:25,320
So you are more than thirty five years old, I might guess you are a developer.

103
00:07:25,370 --> 00:07:27,450
I'm I'm running out of ideas, actually.

104
00:07:28,140 --> 00:07:28,500
All right.

105
00:07:28,510 --> 00:07:31,490
So this one is another else.

106
00:07:31,500 --> 00:07:35,710
If you remember, that leaf is a short for ayliffe.

107
00:07:35,930 --> 00:07:36,290
All right.

108
00:07:36,900 --> 00:07:41,850
And here in the house, just want to print.

109
00:07:43,290 --> 00:07:44,550
Doesn't matter.

110
00:07:44,640 --> 00:07:47,940
Doesn't matter what age you are.

111
00:07:49,050 --> 00:07:51,310
Let's called Biton.

112
00:07:52,200 --> 00:07:52,600
Yeah.

113
00:07:53,970 --> 00:08:02,430
So right now we have all these statements written down here and our age is 30 or so.

114
00:08:02,430 --> 00:08:03,650
Is this statement true?

115
00:08:05,040 --> 00:08:06,030
It's about 50.

116
00:08:06,660 --> 00:08:08,340
Age is bigger than 50.

117
00:08:08,340 --> 00:08:09,660
No age is 30.

118
00:08:09,670 --> 00:08:11,120
So this statement is false.

119
00:08:11,130 --> 00:08:12,570
It would not be executed.

120
00:08:13,320 --> 00:08:15,330
Is age bigger than 40?

121
00:08:15,420 --> 00:08:16,660
No, it's false.

122
00:08:16,680 --> 00:08:19,170
So this one would not be executed as well.

123
00:08:19,530 --> 00:08:21,890
Is bigger than the thirty five false as well.

124
00:08:22,110 --> 00:08:29,730
So what are we going to be a game come up with is this default mode, which is the LTH because all of

125
00:08:29,730 --> 00:08:34,020
these are false for now and this one is the default exit point.

126
00:08:34,440 --> 00:08:40,810
If none of these will be true, the owls would be executed as the default exit point.

127
00:08:41,160 --> 00:08:42,480
So let's try to run it.

128
00:08:43,820 --> 00:08:44,210
All right.

129
00:08:44,970 --> 00:08:53,280
So you see it right now that in matter of fact, like the else was printed and this was the exit point.

130
00:08:53,280 --> 00:08:53,550
All right.

131
00:08:53,910 --> 00:08:56,300
Again, let's try to just do some manipulations here.

132
00:08:56,310 --> 00:09:01,110
Let's just put the age three hundred, all right, like we're a mommy or something.

133
00:09:01,440 --> 00:09:06,420
And once we run it, let's see what happens.

134
00:09:06,960 --> 00:09:07,470
All right.

135
00:09:07,830 --> 00:09:12,620
This this sentence like this if statement was first in line.

136
00:09:12,870 --> 00:09:17,370
So this was the first one to be checked and it came up true.

137
00:09:17,610 --> 00:09:21,670
So this print was executed and once one of them.

138
00:09:21,720 --> 00:09:22,170
All right.

139
00:09:22,490 --> 00:09:29,310
I'm focusing on the sentence once one of them was executed or in other words, once one of these alif

140
00:09:29,550 --> 00:09:40,380
or if one of these conditions was true, the code exits the whole bulk of if completely and continues

141
00:09:40,380 --> 00:09:41,010
down here.

142
00:09:43,500 --> 00:09:44,040
All right.

143
00:09:44,040 --> 00:09:46,370
That's just verified, right?

144
00:09:47,370 --> 00:09:54,390
You see, so once this statement was true and the print this print was executed, they called after

145
00:09:54,570 --> 00:10:00,860
finishing with all of this part because one of them was true, went over to this point right here.

146
00:10:00,870 --> 00:10:09,150
And it ignores all the other else if and Elsas and if so, only one of them can be executed.

147
00:10:09,150 --> 00:10:16,230
And the first one that would be true would be the one to be executed, even though even though that

148
00:10:16,230 --> 00:10:17,960
this statement is also true.

149
00:10:17,970 --> 00:10:18,300
Right.

150
00:10:18,450 --> 00:10:20,940
Because the age is 300 and it's bigger than 40.

151
00:10:21,120 --> 00:10:21,990
Doesn't matter.

152
00:10:22,140 --> 00:10:23,310
It doesn't matter.

153
00:10:24,180 --> 00:10:29,820
The Python Python programming the if statement in Python programming works that way that only the first

154
00:10:29,820 --> 00:10:34,380
true statement would be executed and all the rest would be ignored.

155
00:10:35,730 --> 00:10:36,150
All right.

156
00:10:36,150 --> 00:10:40,050
So that's about it for the advanced part, the basics one part.

157
00:10:40,230 --> 00:10:47,470
And these examples are too huge to be deployed after we learned that during the previous lecture.

158
00:10:48,150 --> 00:10:53,730
So this gives you the feeling what if statements are all about and you see some examples you really

159
00:10:53,730 --> 00:10:55,470
recommend to take this code.

160
00:10:55,710 --> 00:11:02,180
You have it attached to your lecture and to paste it in your pie chart and start to play.

161
00:11:02,190 --> 00:11:08,220
Playing with it like adding equals here and changing the numbers as well as we did right here just to

162
00:11:08,220 --> 00:11:10,140
get the hang of it much better.

163
00:11:10,350 --> 00:11:14,750
And I'll see you in the next video where we can see some more advanced examples.

164
00:11:14,790 --> 00:11:15,860
Thank you and bye bye.
