Programming Skills Required for Data Science: An Overview

Data science is an interdisciplinary field. One that uses scientific methods, algorithms, and processes to extract knowledge from structured and unstructured data. This is also an ever-evolving field.

However, it’s crucial for aspiring data scientists to master the foundations that will give them the background needed to pursue advanced concepts. That will help you to become a professional that’s well sought after in data science.

Being a data scientist means that you’ll help to reduce redundancies and drive innovation by sharing codes, results, and reports. Doing that will remove bottlenecks in the flow of work by simplifying management and incorporating best practices.

You must, however, note that getting a job as a data scientist is no mean feat. But building a portfolio and having a solid hold of all the concepts, tools, and techniques in the Data Science courses to showcase your work will help to boost your chances. Writing a blog about your projects will also help you to gain the confidence of recruiters.

Online job platforms are a good place to find data scientists looking for data jobs. One such platform is Only Data Jobs, the United Kingdom’s largest job board for data and analytics professionals. Through them, your chances of getting data jobs directly from the UK’s most exciting employers will increase.

Programming Skills in Data Science

Data science is a very broad field. One that includes various subdivisions like data preparation and exploration. There’s also data representation and transformation. If you want to learn data science, you can opt-in for Data Science Course.

If you’re a beginner in the profession, it’s natural that you’ll ask certain questions. One of those questions might be, “What programming skills must I have to be a better data scientist? We discuss some of those skills in this article.

1. Cloud Computing

The practice of data science involves the use of cloud computing products and services. This enables data professionals to access the resources needed to manage and process data.

Remember that a data scientist’s everyday role includes analyzing and visualizing data that’s in the cloud. Remember that data science and cloud computing go hand in hand. That’s because cloud computing gives a hand to data scientists to use platforms like operational tools.

You must be familiar with the fact that data science includes interactions with large volumes of data. Considering the size and availability of tools and platforms, understanding the concept of cloud computing is a critical skill.

2. Data Structures and Algorithms

Many people think that data structures and algorithms are things you go through in school but will never need in practice. But you’ll be surprised to know that a lot of interviews involve DSA questions.

There are many reasons why organizations prefer that prospective employees have knowledge in DSA. There is also a reason why data scientists should be interested in it. For organizations like Amazon and Google, writing code is the final step in the long process.

For data scientists, a lot of time is spent considering how to approach a project. That includes the best data structures and the optimal algorithms that must be employed. Such decisions have a real impact on an organization’s usage of resources and profitability.

Thus, it’s no surprise that DSA features in the interviewing process. Such questions help to determine a data scientist’s knowledge and problem-solving abilities.

3. R Programming and Python Coding

R is designed for programming needs and as such, its skills are generally preferred in data science. Its skills can help in solving any challenges encountered in data science.

Note that R programming has a steep learning curve. And as such, it’s difficult to learn, especially if you have mastered a programming language. But despite that, there are resources on the internet that can help you get started.

Another important skill for data scientists is python coding. Python is a great programming language that’s required in data science roles. Thanks to its versatility, python can be used in almost all the steps in data science processes.

It can take different data formats and you can import SQL tables into your code. This allows you to create data sets and you can also find any dataset you need on Google.

4. Database and SQL

One of the basic expectations of data scientists is that they are knowledgeable in core database concepts. That’s because data is the fuel that a lot of organizations run on. Data proliferate in almost every aspect of every project.

There are many languages used to work with databases, but Structured Query Language is the most common. SQL continues to be the standard language used to communicate with relational databases. In recent times, SQL has been heavily used by PC databases. That’s because it facilitates users to simultaneously access the same network.

SQL also allows for easy storage and the organization of data in relational databases. If you’d like to gain experience in SQL, it will be helpful if you practice with MySQL.

5. Data Manipulation and Analysis

Are you aware of what separates a great machine learning project from the rest? Well, it’s data wrangling and analysis. Sure, these two are different steps but they both are included at the same point because of the sequence.

Data manipulation or wrangling is where you clean the data. Then transform that data into a format that can be analyzed better in the following stages. Let’s use packing your luggage as an example.

What would happen if you threw all the clothes into your bag? You’ll certainly save a few minutes. But you know that’s not the right way of doing it because the clothes will be wrinkled. That’s why it’s better to spend a few minutes ironing, folding, and keeping them in stacks to ensure that your clothes remain in good condition.

In the same way, data manipulation and wrangling can take up a lot of your time. But it will ultimately help you in taking better data-driven decisions. Some of the data manipulation and wrangling that’s applied include correcting data and outlier treatment.


Data science has become a revolutionary technology. Termed the sexiest profession of the 21st century, data science is a buzzword with only a few people knowing about the technology in its true sense.

While many people want to become data scientists, it’s important to ensure that you have all the skills required in this field. We have discussed some of the programming skills required. So this is the time for you to seek that knowledge if you haven’t done so already. It will help you to get further ahead in your career.
