00:00:00,750 --> 00:00:03,800
On different models, so let us discuss on it.

2
00:00:05,070 --> 00:00:12,830
A Python model is simply a python source file, which can expose classis functions and global vegetables,

3
00:00:13,110 --> 00:00:19,970
and when imported from another python source file, the file name is treated as a namespace.

4
00:00:20,700 --> 00:00:25,800
So a Python package is simply a directory of python models.

5
00:00:25,810 --> 00:00:27,340
So, so many models are different.

6
00:00:27,540 --> 00:00:29,630
So many libraries are different in Python.

7
00:00:29,730 --> 00:00:33,120
So that's why this python is so powerful that they are nothing.

8
00:00:33,120 --> 00:00:35,640
But these models are nothing but poorly written.

9
00:00:35,790 --> 00:00:36,870
Python source calls.

10
00:00:37,110 --> 00:00:43,680
We can import them in our current model as we are required to use those functions classes as when required

11
00:00:43,920 --> 00:00:47,240
so that we are need not to rewrite the code once again.

12
00:00:47,400 --> 00:00:54,510
So this model importing is actually enhancing the property known as reusability of the programming code

13
00:00:54,990 --> 00:00:58,140
as examples we can go for, say, import non-pay.

14
00:00:58,500 --> 00:01:02,830
Also, we can use some alias that is important vampi as it should be.

15
00:01:03,150 --> 00:01:08,100
So next time, whenever we are supposed to access any component from this non-pay so you can go for

16
00:01:08,100 --> 00:01:13,080
this non-pay dot or you can go for this N.P. dot, in this way we can also access it.

17
00:01:13,380 --> 00:01:15,420
So let us go for one practical demonstration.

18
00:01:15,420 --> 00:01:18,120
For the easier understanding of this.

19
00:01:19,050 --> 00:01:23,570
Is that how to import the different models in our python coding?

20
00:01:24,120 --> 00:01:31,380
We can import our model according to our requirement and also at the same time we can rename it that

21
00:01:31,650 --> 00:01:34,750
can create the alias of the imported model.

22
00:01:35,850 --> 00:01:44,520
So here import math model as M so next time, if I want to use this math name as a model M here instead

23
00:01:44,520 --> 00:01:46,290
of that it will be using M God.

24
00:01:46,710 --> 00:01:53,160
So print the value of pi is m dot by because we have done the renaming of it, we have done the alias

25
00:01:53,160 --> 00:02:02,300
of this math as m so underbite will print the respective by value not use of from from math import byte.

26
00:02:02,310 --> 00:02:04,740
So that is another way to import this by here.

27
00:02:05,070 --> 00:02:07,140
So from math import byte.

28
00:02:07,260 --> 00:02:10,920
So in this case there is no need to write math by here.

29
00:02:10,920 --> 00:02:15,370
You can use directly this by here in our respective print statement.

30
00:02:15,600 --> 00:02:19,500
So if I execute the code, we are getting the output like this one.

31
00:02:19,800 --> 00:02:20,910
Next one is the input.

32
00:02:20,910 --> 00:02:24,150
All names from the Standard Model met in the case.

33
00:02:24,150 --> 00:02:27,180
We can go forward from math import star.

34
00:02:27,540 --> 00:02:33,180
So all the aldosterone, all the names from the Standard Model math will get imported and later you

35
00:02:33,180 --> 00:02:35,670
can use this spy for the printing.

36
00:02:35,670 --> 00:02:37,930
That is a value of pi is by here.

37
00:02:38,310 --> 00:02:43,380
So in this way, in this particular demonstration, we have shown you that how to import models and

38
00:02:43,380 --> 00:02:50,950
how to choose from and how to use this renaming operation while importing our models.

39
00:02:51,420 --> 00:02:52,680
