Is Data Science Hard to Learn?: The Data Science domain is evolving and also presenting a lucrative career opportunity. While the conventional career choices continue to rule, with the growing proliferation of Data Science and allied technologies like AI, ML, and Big Data, many students and professionals are now transitioning into the data domain. This blog covers some of the burning questions in aspiring Data Scientists’ minds.

Whenever you start exploring the prerequisites to become a Data Scientist, a common question that comes to mind is:

  • What programming languages do you need for Data Science?
  • What technical skills do you need to acquire to become a proficient Data Scientist?
  • Are there any other prerequisites to becoming a Data Scientist?

This blog covers some of these questions along with others that often hover in the mind of an aspiring Data Scientist. With these questions and answers, you can find the right path to becoming a successful Data Scientist.

The Relevance of Programming Language in The Learning Process of Data Science

Well, it’s a fact that to interpret and use different Data Science tools, one needs to know certain programming languages like R, Python, and SQL.

  • Python is a programming language used for scripting
  • R is a statistical language
  • SQL is used for managing data in a relational database

Python finds multiple applications, and its use case is not merely limited to Data Science. Machine Learning, Artificial Intelligence, and Big Data use Python. If you are not well acquainted with these programming languages, enrolling in a crash course on programming languages is easy. Understanding Python gives you a competitive edge over others.

Do Data Scientists Need to Code?

Even though you might not need to code regularly, knowing coding is important. The amount of coding Data Scientist needs depends on their job profile. The following examples highlight the same:

  1. A Data Scientist has to work on creating production code using Ruby on Rails or Java
  2. Analysis scripting is done using R or Python.
  3. Creating product prototypes using Python.

Some of the Programming Languages that Data Scientists Need to Know Are:


It is a universal programming language. Not only is it easy to learn, but it comes with several supporting libraries that make its implementation easier and faster. Brainstation’s 2019 survey highlighted that Python is the most widely used programming language by Data Scientists.


It is an open-source programming language. It is an offshoot of the S programming language. It finds application in statistical analysis and predictive analytics. Thus making it a programming language for individuals who want to pursue their careers in the data domain.


SQL, or “Structured Query Language,” has long been used for retrieving data. It is used for managing data in a relational database. It is easy to learn.  Although SQL is not of much relevance when it comes to the analytical part, however, when it comes to managing structured data, then SAL plays a pivotal role.

In addition, there are other programming languages that one can add to their checklist if one wants to excel in Data Science

  • Julia
  • Scala
  • Java

How hard is it to get into data science?

The prospects of growth in the data domain depend on several factors. Individuals who are willing to learn and are constantly acquiring knowledge in this field have fair prospects of growth and excellence.

Acquiring the right skill sets can simplify your learning journey. Whether you are a working professional or someone who is willing to excel in the data domain, acquiring certification in Data Science can give the right impetus for growth in individuals.

There are several data science courses that target beginners. These courses are structured in a way that assures simplified learning while exposing the practical applications of the concepts. Eventually, ensuring a seamless transition of both tech and non-tech background students into the data domain.

What Skills Do You Need to Be a Data Scientist?

A successful Data Scientist needs to acquire skills in certain niches. The different skill sets one needs to acquire to be proficient in the data domain are highlighted below:

Is Data Science Hard to Learn?

Mathematics and statistics

For the Data Scientist, it is important to have a strong foundation. Businesses with a data-driven approach expect Data Science professionals to understand the different statistical approaches, including statistical tests, distributors, calculus, and linear algebra. Hence expertise in mathematics and statistics is paramount.

Machine learning

While it’s not necessary to be proficient with Machine Learning, having a level of familiarity with Machine Learning methodologies will eventually help in the Data Science learning process. Decision trees and logistic regression are key elements that find application in Data Science.

Programming language

The next skill set that a Data Scientist possesses is programming language knowledge. We have already mentioned above that to become a Data Science expert, one needs to know different programming languages like Python, R, and SQL.

Data Visualization

Another key skill set that a Data Scientist must have is breaking down complex data and figuring out important insights. Eventually, a Data Scientist should be able to present this information using different Data Visualization tools like bars, charts, graphs, and others.

Expertise in the Non-technical Domain

Good communication skills

Data Scientists should be well-versed in a programming language and effectively communicate their inferences to a person with non-tech background. Whether you are disseminating the information to the team or your client, effective presentation and communication of information make a lot of difference in the project’s outcome.

Even Data Science has certain specifications which require a technical bent of mind. However, this doesn’t mean that an individual not well acquainted with Data Science concepts cannot pursue a successful career in this field. You only need the right platform and guidance to understand and implement this technology on the ground level. Hence, enrolling for the best Data Science Course will be the right move.
