Hi, welcome back.

2
00:00:01,860 --> 00:00:09,420
In this video, we will learn new by some Web framework called Flask Flask.

3
00:00:10,020 --> 00:00:18,650
Source Code is a python web framework spelled with a small core and easy to extend technique.

4
00:00:18,660 --> 00:00:21,320
But the question here, why is Flass?

5
00:00:21,450 --> 00:00:30,810
I got Web framework, and the answer to this question is, as the following flask is more Pythonic than

6
00:00:31,260 --> 00:00:42,690
the design web framework because the equivalent flask application is more explicit than that Web application

7
00:00:42,690 --> 00:00:44,410
used for the same purpose.

8
00:00:45,210 --> 00:00:56,520
So it is easy for beginners because you can write a few lines of code for getting a simple flask up

9
00:00:56,520 --> 00:00:57,440
and running.

10
00:00:58,440 --> 00:01:07,670
So if we want to create a hello world web application using Flask, the first step to install filters

11
00:01:07,860 --> 00:01:12,930
using Web as the following web install Flast.

12
00:01:13,530 --> 00:01:24,480
So we will open the same Windows operating system or the terminal and Mac OS then type web install flask

13
00:01:24,690 --> 00:01:31,830
as the following, then click enter and Flass package will be installed.

14
00:01:34,880 --> 00:01:45,140
And after installation of last package, we will create a new file and click on Save as they create

15
00:01:45,140 --> 00:01:49,040
a new folder called Hello World.

16
00:01:50,330 --> 00:01:58,820
And then inside this folder, we will save our new folder as Hello World.

17
00:01:59,310 --> 00:02:06,540
But by then we will begin to cut our cap by importing flask.

18
00:02:06,590 --> 00:02:17,330
So from flask import flask with a capital F, then we will assign a variable called F as a following

19
00:02:17,510 --> 00:02:19,690
as a flask object.

20
00:02:19,850 --> 00:02:30,750
So epical flask between two parentheses double underscore name double underscore close the second parentheses.

21
00:02:31,160 --> 00:02:36,580
Now we will use the property of the app as the following.

22
00:02:36,770 --> 00:02:46,130
So at a dot route between two parentheses and two single quotes slash then add a function that contain

23
00:02:46,430 --> 00:02:49,770
the hello world as the following.

24
00:02:50,510 --> 00:02:55,910
So as we learned before, how to create a function.

25
00:02:56,660 --> 00:02:57,410
Yes.

26
00:02:57,890 --> 00:02:58,430
Hello.

27
00:02:58,430 --> 00:03:05,510
Underscore world between two parentheses and empty space then.

28
00:03:06,450 --> 00:03:07,050
Gholam.

29
00:03:08,110 --> 00:03:12,040
Then inside the function, we will return that ring.

30
00:03:12,960 --> 00:03:21,270
Between two single codes, hello, was each capital coma world was.

31
00:03:22,390 --> 00:03:24,460
W cabrito.

32
00:03:25,670 --> 00:03:27,440
Then exclamation mark.

33
00:03:29,190 --> 00:03:34,470
Before we end with the second single court.

34
00:03:36,120 --> 00:03:42,500
Finally, we want to run our app, so we will use the following statement.

35
00:03:42,570 --> 00:03:54,540
So if double underscore name named underscore the word equal between two single code, double underscore

36
00:03:54,540 --> 00:04:04,080
means underscore then column, then inside the F statement, we will use the Trump method so that run

37
00:04:06,060 --> 00:04:07,640
then build our project.

38
00:04:08,760 --> 00:04:17,880
So in the sublime text console window we get that our app is running at the local server, which is

39
00:04:17,880 --> 00:04:30,690
running at each DTV column slash slash one hundred twenty seven point two point 0.01 column, five thousand

40
00:04:30,870 --> 00:04:31,590
slash.

41
00:04:32,430 --> 00:04:39,090
And also it tells me that I can press control and C to quit Xining app.

42
00:04:39,570 --> 00:04:51,840
So I will covid this web address and go to and invested in our Web browser to go to our local host and

43
00:04:51,870 --> 00:04:56,020
check the running flask app as the following.

44
00:04:56,610 --> 00:05:07,200
So I will copy this link at this Zen best and the new window of my Google Chrome Web browser.

45
00:05:07,650 --> 00:05:16,680
Then go to the link, which is a localhost, and we can observe that when we go to the local server

46
00:05:16,680 --> 00:05:21,810
that our app is running okay without no problem.

47
00:05:23,440 --> 00:05:26,110
At this point, we reached the end of this lecture.

48
00:05:26,170 --> 00:05:28,910
I hope you enjoy this lecture and get all of that.

49
00:05:29,290 --> 00:05:32,130
Thanks for watching and thanks for being here.

50
00:05:33,130 --> 00:05:34,840
See you next video.
