This guide will equip you with the knowledge and confidence you need to begin your journey into the exciting world of coding. So, let’s get started!

What is coding?

Product Manager Python

Coding is the act of using computer languages to write instructions that computers can understand and execute. These instructions lay out how the computer will process data, run programs, and store information.

Coding is very similar to writing in that it’s a creative process that requires a lot of problem-solving and critical-thinking skills. However, you can do it by using different tools and languages than what you would use to write a novel or article.

With the rise of technology and the internet, the demand for coders has grown significantly. As a result, coding has become a popular career path and one that is accessible to people of all skill levels.

What are the different coding languages?

Each type of coding language instructs computers to complete different tasks. While each language has its own set of instructions, they all follow a general process. First, you write the instructions in a code editor (it can be as simple as a “text editor”). Once you’ve written the instructions, you need to compile them from source code to maybe code  

From there, you “execute” your application. If everything goes according to plan, your application will work as it’s supposed to. However, if there’s an error in your code, your application won’t work properly and there are debugging tools that can catch errors in your code.

As such, it’s important to know the different types of coding languages and how they work. If you want to get started with coding, you first need to select the type of coding language you want to use. Here are the most common coding languages used today:


Python is a common coding language in data science with applications in visualization, analysis, and machine learning. It’s open source, easy to read, cross-platform, and has a wide audience.


Java is one of the most popular coding languages today, making it a good choice for beginners. It’s an open source programming language that works with multiple operating systems, such as Windows and Linux. It has uses in eCommerce, finance platforms, and content management systems.

C# and C++

C++ is another type of coding language that is very similar to C#. C++ is a popular choice for robotics, game development, and desktop applications. 


Swift is designed to build apps and other types of software for macOS and iOS platforms. If you’re looking to build the next top-selling game in the App Store, you should take look at Swift 


R is a programming language for statistical analysis and data visualization. It’s an open source programming language that has been steadily gaining in popularity.

What tools do you need to get started?

Whether you’re new to coding or have some experience under your belt, there are many resources available to help you get started. First, you’ll need to pick out a code editor and language specification. These are the essential tools you need to get started with coding because they can help catch errors and debug any issues with your code.

Code Editor: A code editor is a piece of software designed specifically to write code. There are many different code editors available, each with its own set of features. You’ll want to find one that works best for you. If you’re going to work with Python, then check out these Python IDEs.

Some examples of code editors include Sublime Text, which is a popular code editor that is available on multiple platforms, including Mac, Windows, and Linux. There’s also Visual Studio, a commercial code editor that is widely used throughout the software development industry.

What are the benefits of learning how to code?

Learning how to code has numerous benefits. First, it can open up opportunities to pursue a career in the technology industry. Learning to code enables you to develop skills that are in high demand, and it can help you think more logically and efficiently.

Secondly, learning to code can be an incredibly rewarding experience. You gain the ability to create something from nothing and it can unlock the potential for building projects that have real-world applications. This can be incredibly rewarding when you can see the tangible results of your efforts.

Thirdly, coding can open up the door to many different career paths. Whether you want to become a web developer, software engineer, or mobile app developer, having these skills can be extremely valuable to prospective employers. As technology continues to become more prevalent in our daily lives, the demand for coders is expected to remain high.

Finally, coding can also help you develop skills that can be used in many other areas of life. By learning how to solve complex problems, think analytically, and break down large tasks into more manageable parts, coding can help hone your problem-solving skills and prepare you for a variety of challenges.

Which careers use Python programming

How do you pick the right coding language?

Choosing the right coding language for a project can be a difficult decision. There are many factors to consider when selecting a coding language, such as the type of project, the complexity of the project, and the skills of the development team.

Technology Stack

When selecting a coding language, it is important to consider the type of project you are working on. Different projects require different coding languages. For example, web development projects may require HTML, CSS, and JavaScript, while mobile applications may require languages like Java and Swift.

The complexity of the project is also an important factor to consider when selecting a coding language. Projects that are small or simple in scope may not require a complex language like C++. On the other hand, large or complex projects will likely need a language with more features and capabilities.

Another important factor to consider is the skills of the development team. Different coding languages require different levels of experience and expertise. If the development team has limited experience with certain coding languages, it is important to select a language that they are comfortable with.

Finally, it is important to consider the cost associated with different coding languages. Some languages, such as Java and C++, require more expensive development tools, while others, such as Python, are free. Additionally, the cost of hiring experienced developers may vary depending on the language they specialize in.

How can you start with coding?

Getting started with coding can be a daunting task at first, but with the right resources and motivation, it can be a rewarding experience. My recommendation is to get right into it and start coding. Our top recommendations are:

DataCamp – DataCamp’s courses are designed to be interactive, with a mix of videos, coding exercises, and quizzes. It offers both free and paid subscriptions, but you can get a lot out of the free version.

Dataquest – Dataquest is an online learning platform that offers interactive courses in data science, data analysis, and data visualization. One of the unique features of Dataquest is its emphasis on guided projects, which are interactive learning experiences where learners are given a problem to solve and are guided through the process of solving it.

Udacity – Udacity is an online learning platform that offers courses and nanodegrees in a variety of subjects, including computer science, data science, artificial intelligence, business, and more.

What are the best coding practices?

The best coding practices involve writing code that is easy to read and understand, efficient, maintainable, and secure. This involves following industry standards, using proper syntax and formatting, commenting on your code, naming conventions, using version control, and writing clean code.

Good coding practices also include testing the code thoroughly to ensure it’s working properly, validating user input, ensuring the code is free of bugs and vulnerabilities, and following best practices for security. Additionally, it’s important to document your code and keep it up-to-date.

These practices help ensure that your code is reliable, manageable, and secure. Following these guidelines will save you time and energy in the long run, as well as help you produce high-quality software.

What are the different coding career paths?

There are many different coding career paths available for those interested in pursuing a career in computer programming and software development. These include web development, mobile app development, game development, data science, machine learning, artificial intelligence, and cybersecurity.
