1
00:00:00,920 --> 00:00:05,120
Pythonesque that assertions can be implemented in bichon.

2
00:00:06,080 --> 00:00:12,560
Assertions are statements that assert our state a fact confidently in our program.

3
00:00:13,040 --> 00:00:19,250
So, for example, while writing a division function, we are confident that this is the that should

4
00:00:19,250 --> 00:00:20,180
not be zero.

5
00:00:20,210 --> 00:00:26,120
We know that division by zero is illegal and we asserted deviser is not equal to zero.

6
00:00:26,720 --> 00:00:33,240
Assertions are simply boolean expressions that checks, if the condition returns, is true or not.

7
00:00:33,680 --> 00:00:39,660
So if it is true, the program does nothing and move to the next line of the code.

8
00:00:39,830 --> 00:00:45,000
However, if it is false, the program stops and throws an error.

9
00:00:45,440 --> 00:00:47,940
So that is a basic principle of assertion.

10
00:00:48,170 --> 00:00:50,540
So let me repeat once again for the clarity.

11
00:00:51,020 --> 00:00:56,420
Assertions are simply boolean expression, so it will return true and false that chix in the condition

12
00:00:56,420 --> 00:01:00,720
return is true or not if it if it is the truth.

13
00:01:00,740 --> 00:01:05,350
The program does nothing and move to the next line of the code if the condition is true.

14
00:01:05,960 --> 00:01:09,900
However, if it is false, the program stops and throws an error.

15
00:01:10,070 --> 00:01:12,680
So that is known as the assertion in Baton.

16
00:01:14,580 --> 00:01:23,100
So it is also a debugging tool as it brings the program on hold, as soon as any error is occurred and

17
00:01:23,100 --> 00:01:26,910
shows on which point of the program, the error has occurred.

18
00:01:27,060 --> 00:01:30,450
So that is a special features of assertion.

19
00:01:31,020 --> 00:01:32,320
So previous code is there.

20
00:01:32,460 --> 00:01:34,320
Now we are having that session condition.

21
00:01:34,530 --> 00:01:38,880
If the condition is true, then the program continue to run.

22
00:01:39,090 --> 00:01:45,840
If the condition is false, then the assertion stops the program and gives us an error and also the

23
00:01:45,840 --> 00:01:49,630
respective point where that particular error has occurred.

24
00:01:49,770 --> 00:01:53,570
So that will be mentioned in the assertion error session later.

25
00:01:54,060 --> 00:02:00,210
So for the better, let us go for one practical demonstration will be showing you that how this assertion

26
00:02:00,420 --> 00:02:02,940
can be implemented in Biton.

27
00:02:03,820 --> 00:02:11,500
We know that assertions are statements that assert our state, in fact, confidently in our program,

28
00:02:11,920 --> 00:02:18,280
for example, while writing a deficient function, you are confident that the deviser should not be

29
00:02:18,280 --> 00:02:18,670
zettl.

30
00:02:18,910 --> 00:02:24,230
In the case, we can prove we can insert one assert device that is not equal to zero.

31
00:02:24,280 --> 00:02:24,950
Accordingly.

32
00:02:25,510 --> 00:02:32,020
So assertions are nothing but simply boolean expressions that checks if the condition returns, true

33
00:02:32,020 --> 00:02:37,120
or not, if it is returning to the program does nothing and move to the next line of code.

34
00:02:37,450 --> 00:02:42,300
And if it returns false, the program stops and throws an error known as the assertion.

35
00:02:42,310 --> 00:02:47,710
Edit so as an example, consider this one where defined one function.

36
00:02:47,710 --> 00:02:52,680
The name of the function is Avijit, which will take this marks the least as input document.

37
00:02:53,200 --> 00:02:54,010
So assert.

38
00:02:54,010 --> 00:02:56,290
Lynn Marks is not called digital.

39
00:02:56,440 --> 00:03:03,400
If the condition is true, that means if the length of this list is not equal, that means the list

40
00:03:03,400 --> 00:03:04,450
is not empty.

41
00:03:04,900 --> 00:03:10,510
If the condition is true, then it will go for the sum of marks by laying up the marks to calculate

42
00:03:10,510 --> 00:03:12,030
the average and that will be returned.

43
00:03:12,730 --> 00:03:19,330
So but if that length of marks is not equal to zero, if the condition is false, then it will produce

44
00:03:19,330 --> 00:03:20,190
the assassinator.

45
00:03:20,770 --> 00:03:26,800
So for the first run, we are making one least available, which is non-empty and we are trying to calculate

46
00:03:26,800 --> 00:03:30,970
the average of them and we are going for the next one with the list is empty.

47
00:03:30,970 --> 00:03:33,680
al-Atassi, what is the outcome we are going to have?

48
00:03:34,570 --> 00:03:39,820
So just see, in the first case we are having this 11 plus 22 plus 33 whole battery.

49
00:03:39,820 --> 00:03:40,980
So I'll be teaching with the value.

50
00:03:40,990 --> 00:03:41,740
Twenty two here.

51
00:03:42,100 --> 00:03:47,980
So average of Mach one is equal to twenty two, so average of one is twenty two is getting executed,

52
00:03:47,980 --> 00:03:49,000
is getting printed.

53
00:03:49,450 --> 00:03:56,350
And now in the second case we are passing this, we initializing this mock one with the null list that

54
00:03:56,350 --> 00:03:57,640
is containing new element.

55
00:03:57,850 --> 00:04:00,820
So the length of this mark one will be zero.

56
00:04:01,150 --> 00:04:04,810
So length of Mach one is not equal, digital recognition will be false.

57
00:04:04,960 --> 00:04:07,840
So it will produce one error known as the assassinator.

58
00:04:08,200 --> 00:04:09,940
So that is known as the assassinator.

59
00:04:10,960 --> 00:04:16,060
So not only the throwing the assassinator, also we can put some error message also, so let us go for

60
00:04:16,060 --> 00:04:16,370
that.

61
00:04:16,930 --> 00:04:22,980
So here to see if the ruling Assad land of the Marxist nautical digital, that list is empty.

62
00:04:23,290 --> 00:04:27,000
So the condition is true that Mr. Length of is not legitimate.

63
00:04:27,010 --> 00:04:29,250
That means the list is not empty.

64
00:04:29,530 --> 00:04:35,080
In that case, it will produce true and it will go to the next line without any interruption authorized

65
00:04:35,080 --> 00:04:40,480
assassinator will be will be obtained and it will be having this message to get printed.

66
00:04:40,510 --> 00:04:42,430
So now let me go to execution.

67
00:04:42,850 --> 00:04:45,930
Matou is not all it is having some value there.

68
00:04:45,940 --> 00:04:47,560
So the average will get calculated.

69
00:04:47,890 --> 00:04:50,380
I think as a mark one it is another list.

70
00:04:50,530 --> 00:04:53,710
So I think that here translation error will be thrown.

71
00:04:53,950 --> 00:04:54,900
So just see here.

72
00:04:55,150 --> 00:04:57,820
So average marks of MC2 is 78.

73
00:04:58,150 --> 00:05:00,230
So 78 is the average marks of marks.

74
00:05:00,820 --> 00:05:05,090
But in the case, in the next one, as a mark, one was having the empty list.

75
00:05:05,470 --> 00:05:08,440
So this particular assassinator has taken place.

76
00:05:08,560 --> 00:05:12,690
And here to see the message has got printed, that is a list is empty.

77
00:05:13,120 --> 00:05:15,150
So there is a message you have given this one.

78
00:05:15,580 --> 00:05:18,190
So this giving this message is optional.

79
00:05:18,200 --> 00:05:24,010
You may or may not give as here we have given and but in the previous example, we didn't give any such

80
00:05:24,010 --> 00:05:24,770
error message.

81
00:05:25,330 --> 00:05:30,520
So I think now that what is a solution in Python, the concept is now getting clear to you.

82
00:05:30,760 --> 00:05:32,050
Thanks for watching this video.
