How To Write The Clean Or Maintainable Code in 2023

Get The Clean Or Maintainable Code- How?

Getting your software or developing the one by yourself is not so handy thing to do. It requires a lot of effort and also the knowledge. You have to learn a lot about coding, and then you can create your software or website. Coding is one of the building blocks of any software.

Coding is difficult, but in this generation, even children of 8 to 9 years know about the coding system because of their passion. You can learn coding easily with some tips and tricks, and these tricks make this coding world so easy. 

While creating the software, it is very important to create easy or maintainable codes. Because you need to remember the code to keep all of your software. Clean code means this software is easy to understand or maintain. However, creating a clean or maintainable code is tricky.

You will have to use your mind to create simple or handy codes that make your software more understandable. In this article, we will tell you what is meant by clean code and how we can generate clean code for the easiness of software. 

Clean Code

You might have heard the phrase” clean code” in software development. This is a very common phrase for software developers. Clean code is the computer code that is easy to read, understand, or maintain. Clean code should be the simplest one with conciseness and also expressive. That special code should be free from any trouble; there should not be any unneeded things or conventions in the code. For clean code, make sure it is forever free of anti-patterns. 

When you use the most straightforward or easy code, it makes it more easy for the developer to work on the codebase. And with this easiness, you can increase the software’s productivity and lower the chance of error. So, if you want your software to be fair enough, you must always use easy or clean codes. When you are creating long-term software, you have to be very cautious with the code that should be maintainable so that that code can be edited or enhanced over time. 

How To Write Clean Or Maintainable Code

To write clean or maintainable code, you have to point out some crucial factors in your mind, which is essential. Always ensure that the code you use in your software or codebase is effortlessly maintainable or clean; otherwise, it might make problems in the software. Let’s explore the tips and tricks to make your code more clean and maintainable.

1. Consistent Coding Style

Following a consistent coding style for even the most recent software is important in developing clean code. Coding style is a set of policies or instructions for generating the code, how you should develop the code, and the design and structure of the code.

Following the ancient coding system will make it easy to understand that code and be more legible. Using the old explanatory or meaningful variables in your codes will make your code more intended or easy for developers. While creating the code for software, confirm the proper use of spacing and indenting.

Always use the single casing format in your coding. Avoid using the mixture of snake_ case and camel case. As it will make your code more baffling and vague, it will take much work to follow in the long run. The Google Style Guide, Airbnb Style Guide, and PEP 8 Style Guide for Python are commonly used coding styles. 

For composing the code, architecture is also very important; before writing the code, describe your architecture principle to make it easy for a developer in the codebase. At last, you can use the linters and code formatters to enforce the coding style guidelines. These tools will be helpful to catch any errors or issues in the code. 

2. Make It More Simple

Clarity is also the key element in creating the more clean or maintainable code. As we have said many times in our article, easy or simple code makes your software or code data readable in the most comfortable way and can also be easily debugged. Don’t make your code simple and easy to read; use briefness in your codes with function names. You can also use your code’s comment to explain complicated code or algorithms. 

3. Use Comments Or Documentation

Comments or documents are used in developing different codes. Comments are used to define the hard-to-read or complex codes, and you should also use comments only in that situation. Comments or documentation will help your code to be more maintainable over time.

If you are using any documentation in your code, ensure that it is accurate and provides exact or clear education about the codebase, how to use it, or how to maintain it. If you use the comments in your coding system, follow these tips to create the right comments for the code.

A. Comments should not be similar to the code.

B. If you are using external references, make sure you use the links so that they can be easily accessed.

C. If there are any bugs in your codes, then make sure to add a comment about the fixing of that code.

D. Always use the comments to point out insufficient implementations in your code.

E. If you are using good comments to cover up the nuclear codes, it won’t happen.

F. Your code might need fixing if you can’t write a clear comment about it.

G. If you have copied the code, paste the source of it.

For documentation, use the examples in it so that you can easily explain the workings of that particular code and how it should be used. Also, ensure that the documentation is always up to date.

4. Conciseness Or Clarity

When writing the clean code, ensure you balance conciseness and clarity correctly. Many people need help with this mistake when trying to make their code more concise. They make it more unclear, which, as a result, creates huge problems. So, while making your codes concise, also focus on the clarity of the code.

Suppose the conciseness of the code is important for maintainability and readability. In that case, code clarity is equally important so that your code will be easily understood or clear for developers. Please don’t go for the overly concise code for conciseness, as it may confuse or make your code unclear.

You have to make the code that much easier so that other developers can easily read or comprehend it. It’s not like they will steal it, but they should understand it. If you are a developer, you might have faced somewhere that you look at the code and be like, “Ooh, it’s so concise,” but when you start reading it, you can’t understand it and can’t even get its meaning. That’s the reason why a code should not only be concise but also straightforward. 

5. Reusability

All the codes can be reused in another part of your software or application; even you can use the whole code in another application. Remembering that you have to make your code reusable is a good idea. To make your code more modular, you must break it down into smaller or reusable functions.

Those all small particles or your code will be for specific functions in the software. It will make it easy to maintain and reuse the code in later applications or softwares. In your whole project, use the codes distributed in different small parts so they can be reusable.

Attempt not to use any tight connection between two elements of codes; instead, you can use the interfaces or abstract classes to decouple the components and make them in a new reusable form. In software engineering, code reusability is very significant, and it will create easiness for developers to use that code in different applications without any modifications.

The reusability can improve the productivity and efficiency of software development. When developers develop new software, they use the old, earlier-used code that will save time and struggle and improve the quality of code and consistency. 

6. Test Your Code Accurately

Always test your code frequently so that you can make sure that it is clean, maintainable, and bug-free. Many sites or programs are available to help you test your code and ensure it is ready. Test Driven Development is the process in which you can do the writing tests before writing the actual code, which can help you ensure that your code is testable and ready to go. 

To use the Test Driven Development in your code, make sure you follow these steps:

A. First, you have to create a clear test for your code. You have to do this to ensure it can execute and the functionality of specific parts.

B. You can also do the correctness of your code. If the test fails, make tiniest changes in the code so that it can be successful while re-executing. 

C. Once you have run the test and it goes successfully, check for any unneeded things in the code and any change that can enhance the overall performance. 

7. Naming

When using name variables in your code, make sure you use them perfectly, and the functions should be clear or defining. It will help you to create code that will be maintainable or legible in the codebase. Choosing the name correctly will help other developers as they can quickly comprehend it and know what this particular variable or function is doing and the correct relation between this part and the other part of the code. 

Benefits Or Clean Code

Many benefits of clean codes include:

i. Clean codes are easy to comprehend or read, which makes it easy for the developer to adapt and maintain.

ii. Clean codes are error-free or more trustworthy. There is no bugs or mistake in the code.

iii. As clean code is easier to understand, it improves the developer’s productivity and efficiency. 

iv. Those easily maintainable codes can be edited or modified easily, even in the future.

v. Clean codes are very easy to check as they are arranged in a methodical manner. As a result, the reviews are more efficient or effective

vi. Clean or maintainable code is easy to reuse. You can reuse the whole code in a different application without modification and save time or effort. 

vii. Clean codes are easy to understand by other team partners, which can improve team cooperation and communication between them.

viii. Clean codes are more efficient and can run faster because they have less complexity. 

From these things, writing the code requires little measure. But that effort can be one time because if your code is reusable, you can reuse it in other applications later on. Some information and tricks can make your code more useful or efficient.


Writing code for your software is easy and easy, but only if you compose it with effort or obey little tips or tricks. These small considerations can make your code more effective or efficient. Your code should be simple or concise and free of any complexity.

If you write good code, it will also improve the quality and reliability of your software. Following little practices while generating your code can make your work more easy and handy. In this article, we have shared some important tips or tricks with the help of which you can easily generate the code that will be effective for your software.

Write code that is easy to go and understandable. It will make it easier for the developer to manufacture the software as he does not have to worry more about reliability or maintainability. You have to follow the simplicity, consistency, or preciseness in your code. Some other factors can also be key in generating clean or maintainable code.


1. Which Code Needs To Be Cleaned?

You can know the code is not clean or maintainable if :

  • l The code is long or with a complex function that is difficult to understand.
  • l code with poor naming, like short variable nondescriptive names.
  • l Codes that follow the inconsistent styling format.
  • l Codes that make the test automation more hard.

2. Can We Use The Whole Code In The New Application?

Yes, you can use the whole code in the new application, and also you can use the components of code in later applications.
