00:00:04,720 --> 00:00:08,650

Rest APIs advantages in usage.



2

00:00:09,010 --> 00:00:09,760

Hello, everyone.



3

00:00:09,790 --> 00:00:16,780

Today, we're going to talk about the APIs and their advantages in programming using Python.



4

00:00:17,050 --> 00:00:19,570

First of all, let's talk about what is API.



5

00:00:19,750 --> 00:00:26,110

API is basically the application that translates the data that you receive online to you.



6

00:00:26,380 --> 00:00:34,510

For example, if you send a message on Facebook, for example, to a friend, what you actually do is



7

00:00:34,510 --> 00:00:36,250

send the message to Internet.



8

00:00:36,570 --> 00:00:43,310

Then the message is processed and your friend receives your message in words, OK, in reverse so that



9

00:00:43,310 --> 00:00:44,210

he can understand.



10

00:00:44,470 --> 00:00:51,610

So that translation from the Internet to their source to the message that your friend actually gets



11

00:00:51,850 --> 00:00:53,740

is the API process.



12

00:00:54,010 --> 00:01:00,190

So as you can imagine, there are different API tools that are used by programmers in order to translate



13

00:01:00,190 --> 00:01:07,270

the Internet data to an actual data that a programmer or a user can actually use.



14

00:01:08,110 --> 00:01:15,850

So within the web system, we're using an API call to rest and what the rest is basically doing, it



15

00:01:15,850 --> 00:01:23,440

uses the HTP protocol, went into this Internet and then takes the data from the Internet and process



16

00:01:23,440 --> 00:01:29,620

it presents it in easily readable form, such as XML or JS on file.



17

00:01:30,400 --> 00:01:36,880

So as you can see, there are many advantages over the rest API protocol because this is one of the



18

00:01:37,900 --> 00:01:41,530

most used API actually out there.



19

00:01:41,800 --> 00:01:45,730

And the main advantages are on the first place.



20

00:01:45,730 --> 00:01:46,450

Automation.



21

00:01:46,810 --> 00:01:48,640

The scope is automatic.



22

00:01:49,210 --> 00:01:57,880

This sort of simplifies when you obtaining the data from Internet, you can even use the API of some



23

00:01:57,880 --> 00:02:03,250

Web service with your own code in order to obtain or modify the data that you receive.



24

00:02:03,550 --> 00:02:10,420

The second main advantage over the rest API is that it completely separates the clan from the server.



25

00:02:11,170 --> 00:02:19,240

This actually enables the different companies to evolve independently and different the increases,



26

00:02:19,240 --> 00:02:27,470

the portability of that type of API as it can be used separately from each client, also sits on a server.



27

00:02:27,820 --> 00:02:35,200

Obviously, this protocol also has the capability of external access, which means that every user is



28

00:02:35,200 --> 00:02:43,570

able to access the website externally just by providing a password and user name and using the Internet



29

00:02:43,570 --> 00:02:44,770

from remote point.



30

00:02:44,890 --> 00:02:53,860

So for that reason, in this section, we're going to concentrate on the risk APIs, Jason and XML files,



31

00:02:53,860 --> 00:02:59,790

and you'll see how data is actually extracted from Internet current interest for this type of files.



32

00:02:59,800 --> 00:03:04,200

And we're also going to concentrate on how this type of files look like system.



33

00:03:04,210 --> 00:03:12,350

For example, the XML file is one of the most widely used types of files in the companies.



34

00:03:13,090 --> 00:03:20,170

And I can tell you from my personal experience that this is something that many students do not study



35

00:03:20,170 --> 00:03:21,250

in university.



36

00:03:21,450 --> 00:03:29,990

However, absolutely every company I work for is using XML and Jason files in order to translate data.



37

00:03:30,340 --> 00:03:37,660

So this section right now, it's actually very, very important for you if you want to learn just basic



38

00:03:37,670 --> 00:03:39,900

skills that you can use in your workflow.



39

00:03:40,300 --> 00:03:48,730

So keep watching, concentrate and do the tasks of the course once they can get to your deserved and



40

00:03:49,420 --> 00:03:51,020

well desired job.



41

00:03:51,850 --> 00:03:52,640

So that's it.



42

00:03:52,660 --> 00:03:54,790

This will be the end of that introduction video.



43

00:03:54,860 --> 00:03:59,050

Guys, thanks for watching and bear with me in the next video.



44

00:03:59,070 --> 00:03:59,890

So that section.
