00:00The quality of the code is directly related to readability and cleanliness.
00:11How clean code is written and how new code is used for it is easy to use code.
00:18The first step is documentation.
00:24The first step is to define the code when the next user uses the function.
00:32For example, this function has written a print function.
00:38Basically, Python and volunteers have written a lot of programmers.
00:44Let's see what this function is.
00:46What if I want to know more about this function?
00:49How can I know about this function?
00:50I can call the help function.
00:54I can simply say that I will help.
00:56I will execute it.
00:58And then, look, this is all the help.
01:01This function is a print function.
01:03This parameter is a value, separator, end line.
01:06This file can also be used for flush.
01:09This options are the options.
01:11Then, the details of the print function is a value.
01:14Then, it will be operation.
01:16It will be file, separator, end.
01:18option is what we can do.
01:19We can insert string between value and defined space.
01:22Cool.
01:23So this means that if I look at this print function, if I look at this complete usage, then
01:31I can understand it.
01:32It's like I have a function called, and all the things I have made in my face.
01:36So, you can see that you have a function of the content to the function.
01:43We can see that it is descriptive.
01:45So you can see it.
01:46So we can select the function of the function.
01:49Then we can select the function of the function.
01:52And you can see nothing.
01:55Basically, you should be able to see that you don't see anything.
02:01You can see that you can see a string here.
02:06And that's it.
02:09So you can see that the function of the function is called.
02:12So, the print function has helped add, how can we add?
02:18We can use Doc String to use Doc String to add.
02:21Doc String to define three double quotes or single quotes.
02:25For example, I put single quotes three times,
02:29or double quotes three times, just like this,
02:32and closing three times double quotes, just like this.
02:35Now, what you can write is the Doc String to help.
02:41For example, I say,
02:43function creates,
02:49and then I say,
02:54and then I say,
02:56name takes name, amount takes amount, amount is returned so that it can be used further.
03:17Further.
03:18Okay.
03:19So, what do you do?
03:20What do you do?
03:21That is the description.
03:22The amount is returned,
03:23and you can use it further.
03:24If you call the help function on the receipt,
03:28then you can see what happens.
03:30Wow!
03:31Now, your function is more descriptive.
03:32Basically,
03:33the code is not needed to see the user.
03:37It's simple.
03:38It's simple.
03:39You can say,
03:40this is the receipt.
03:41I can see,
03:42this is the receipt function.
03:43I can tell you,
03:44it's built-in.
03:45This is how to use it.
03:46How to use it?
03:47Help function is called here.
03:48Okay.
03:49Name and amount.
03:50Receipt function create receipt.
03:52Okay.
03:53Good.
03:54Name.
03:55Name.
03:56Amount.
03:57Amount.
03:58Amount.
03:59Amount.
04:00Amount.
04:01Amount is a string.
04:02Okay.
04:03Amount is a string.
04:05Okay.
04:06So,
04:07idea is better.
04:08Okay.
04:09I will execute it.
04:10Now,
04:11directly,
04:12help show us.
04:13You can use a new user.
04:15Okay.
04:16It's a very,
04:17very big help.
04:18That,
04:19that it is easy to know.
04:20That,
04:21okay.
04:22This function,
04:23value,
04:24return to the value.
04:25This is an entire user.
04:26So the code application has been added.
04:27You can add the code.
04:28As far as if,
04:29the code is possible,
04:30you can add the code.
04:31The code is also important.
04:32But,
04:33you know,
04:34you can add the code.
04:35It's better for the code.
04:36You can add the code,
04:37now,
04:38you can add the code.
04:39This is a inicioul.
04:41This is a recipt.
04:43This is a recipt.
04:45This is a recipt.
04:47This is a recipt.
04:49Just like that.
04:51I can copy, control-C, control-V can go on.
04:53And this is a recipt.
04:55They are not the same thing.
04:57They are not the same thing.
04:59They are not the same thing.
05:01Help function in this composition
05:03This has just a static string.
05:05Okay?
05:06You can use it anywhere.
05:07You can use it.
05:08You can use the help method and retrieve it.
05:11This is just for readability.
05:13For example, I will remove it.
05:16And I will simplify it.
05:18This function creates zipped.
05:20I will say this is done using commenting.
05:26Okay?
05:27If I call help function,
05:29basically, help function is totally ignored.
05:32Hashtag is not dot string.
05:35Dot string is when you want to document your code.
05:38You want to give a description.
05:40So, you can use the help function.
05:44Excellent.
05:45You can also see the help method.
05:50Basically, dinder method.
05:52You can double underscore.
05:54Dock double underscore.
05:56You will get exactly the same result.
06:00Okay?
06:01So, this is basically dinder method.
06:04Basically, we will print it here.
06:07To see the result.
06:08So, I will print it.
06:10Wrap up.
06:11This dinder method is called object oriented programming.
06:13We will learn to do two method methods.
06:15You can use the help function function.
06:17You can use the help function function.
06:19You can use the help function function.
06:21So, again, you will show the help.
06:23Okay?
06:24So, let's close this to you.
06:25Here is a small step to you.
06:26That I will share the extension method.
06:27This is the return method.
06:31It is not.
06:32Right?
06:33I am sorry.
06:34I am sorry.
06:35That is the return method.
06:36You can just write it.
06:38After this option.
06:39I don't give up.
06:41You can write it.
06:42So, I am going to put it this way.
06:43This is the return method method.
06:45But, you can write.
06:46Like, this is the return method.
06:47그러면,
06:48You can write it.
06:49return encounter ہوتا ہے
06:50loop, joh block of code
06:53ہے, وہ break ہو جاتا ہے
06:54तो line 59
06:57execute ही نہیں ہوگی
06:59तो आपने यह चीज़ अपने जहन में रखनी है
07:00कि return, first time
07:02used हुआ, excellent, second time
07:05not accepted, ठीक है
07:06यहाँ पर 59, जो है, वो execute ही
07:08نہیں होगी, तो आपने यह चीज़ अपने जहन में
07:10रखनी है, कि return, first time
07:12जब use हुआ, excellent, second time
07:15not accepted, ठीक है, यहाँ पर code break हो जाएगा
07:18और यहाँ पर exit कर जाएगा
07:20code, ठीक है, इस line पर
07:22इसके नीचे जाएगा ही नहीं, ठीक है
07:23तो आपने यह चीज़ अपने जहन में रखनी है
