How to use ChatGPT to Code

It’s possible to use ChatGPT to code your next big application all thanks to Artificial Intelligence which has revolutionized many fields, including programming. With the advent of language models such as ChatGPT, and the GPT-3 API, as a developer, you can now leverage the power of natural language processing to write code faster, and spend the rest of your time debugging any errors.

You can use ChatGPT to code in popular languages such as Javascript, NodeJS, C, C++, React, Python, Ruby, Bash, among other variants. In this article, we’ll explore how you can use ChatGPT to code and some best practices you should follow to write better code.

Ways you can Use ChatGPT to Code

  1. Code generation: ChatGPT can generate code based on natural language descriptions of programming tasks. This is a huge time-saver, especially for more complex tasks. To use ChatGPT for code generation, you simply provide a natural language description of what you want the code to do. ChatGPT will then generate a code snippet that accomplishes that task.


To generate a full Python program that requests user input in a language and tests the data against a provided database of variables. Enter the following text in ChatGPT:

 `Using Python 3, write me a program that requests user input and authenticates it against a list of variables ranging from 18 to 65, please use conditional statements where necessary’
use ChatGPT to write Python Code

Based on the above description, ChatGPT will generate code that tests if the user’s age is above 18 years old. Depending on your desired program details, provide a more in-depth command for better code.

However, ChatGPT is not as perfect as a human, each time you generate code using ChatGPT, make sure you copy the Snippets to your IDE such as Visual Studio, and make edits where necessary.

  1. Code completion: Another helpful feature of ChatGPT is its ability to suggest code completions based on partial code snippets. This helps speed up your coding process by reducing the amount of typing you need to do, as well as reducing errors.

To use ChatGPT for code completion, provide a partial code snippet of your program, and ChatGPT will suggest possible completions. Make sure your intended auto-completion is the last statement in the code so that it best auto-completes it to the best possible value.

  1. Code review: ChatGPT can review code for errors or inefficiencies. This helps you catch and debug errors that might otherwise go unnoticed. To use ChatGPT for code review, paste the code that you want to review in the chat prompt, and press enter.

ChatGPT will analyze your code, suggest improvements, and highlight errors. If no issues are found, ChatGPT will give you the green light that your code is good.

  1. Code documentation: If you have a complete program you want to generate documentation for, then ChatGPT can save you time by understanding your code and generating a write-up for your target audience. To use ChatGPT for code documentation, instruct ChatGPT to follow your rules and write documentation for your program. For example:
Write documentation for my program code pasted below, make sure it follows the plain language, less complicated for a beginner, and has little to no grammar errors. <Paste-code>

Based on the above prompt, ChatGPT will generate a description describing your code’s functionality and usage in plain English. If you are not impressed by the documentation, instruct ChatGPT to re-do the task.

Best Practices to follow when Using ChatGPT to Code

  1. Be Specific: ChatGPT is not human, so, it can easily give you very wrong information if it fails to understand your prompt well. If you are a direct copy and paste without reading user, you will encounter lots of errors in return.

So, when using ChatGPT for code generation or completion, be specific about what you want the code to do. This helps ChatGPT generate accurate code that meets your needs.

  1. Proofread ChatGPT generated code: Much as ChatGPT is good when it comes to coding, it’s very important to double-check any code snippets that it generates. This is especially important if you want to use the code in a production environment.
  1. Keep learning: ChatGPT is a powerful tool, but it’s not perfect as a human. Just like any other tool, there are limitations and areas where it may not be helpful. So, It’s important to keep learning and expanding your programming knowledge so that you are less dependent on ChatGPT since it can easily generate imperfect code.

In conclusion, ChatGPT is a powerful tool that can help you make coding faster, more efficient, and error-free. By following some best practices, developers and beginners alike can leverage the power of natural language processing to write better code.

As a rule of thumb, it’s important to remember that ChatGPT is just one tool in a developer’s toolkit, so, you should use it in conjunction with other programming tools such as GitHub, and your Integrated Development Environment (IDE).
