List Of The Best Programming Languages Among Data Scientists


If you’re considering a career in data science, it’s best to start learning to code as soon as possible. The essential first step for any aspiring data scientist is learning how to code. But if you have never done something, learning to program could be scary.


Numerous programming languages that were created for distinct purposes are now widely available. Some of them are more suited to data science because of their high efficiency and capacity to handle significant amounts of data. Many programming languages still fall under this category, though.


Several top data science languages until 2023 will be examined in this article, along with each language’s advantages and weaknesses.


  • Python

  • R

  • SQL

  • Java

  1. Python

According to numerous popularity gauges, Python is now the most well-known programming language, including the Innovation Index and or the PYPL Index. Python is a general-purpose, open-source programming language with many uses, including web development, video game creation, and the data science tasks.


You can literally accomplish any data science task you can think of using Python. This is usually because of the environment’s enormous library.


  • A popular package called NumPy provides a sizable selection of sophisticated mathematical functions. Numerous packages, including the well-known NumPy arrays, are built using Numpy objects.


  • Data science relies heavily on the pandas’ library, commonly known as DataFrames, which is used to manipulate databases in various ways.


  • The typical Python library for data visualization is called Matplotlib.


  • Based on the combination of NumPy and SciPy, sci-kit-learn has emerged as the most widely used Python toolkit for creating machine learning algorithms.


  1. R

R is a leading choice for many aspiring data scientists despite Python’s popularity indices showing a higher current trend. Learning one of those two languages is essential to breaking into data science and AI because it is frequently depicted as Python’s main rival in online data science forums.


R is a free, open-source, and specifically made-for data research language. R is a wonderful language for data manipulation, processing, visualization, statistical computing, and machine learning. It is very well-liked in finance and academia.


Learning R is still a great option whether you want to expand your linguistic repertoire or are new to data science. To start honing your skills, go through the comprehensive data analytics course in Mumbaiwhich includes special programming classes for data science aspirants. 


  1. SQL

You must that most of the world’s data is stored in databases. Programmers can interact with, modify, and extract data from databases using the domain-specific language SQL (Structured Query). You need to be knowledgeable of databases and SQL if you want the work as a data scientist.

You may work with relational databases, including well-known ones like SQLite, MySQL, and PostgreSQL if you are familiar with SQL. SQL is a relatively flexible language because, despite the minor variations across various RDBMS, the syntax to basic queries is comparable.


Whether you decide to begin your data science adventure using Python or R, you should think about picking up SQL. Unlike other languages, SQL is quite straightforward to learn and will be very helpful to you along the way because of this.



Java is ranked #2 mostly in PYPL Rankings and #3 in the TIOBE Index, making it one of the more popular languages for programming in the world. It is a well-known open-source, object-oriented language that excels in efficiency and performance. Most websites, technologies, and software applications rely heavily on Java environments.


Although Java is a favored option when creating websites or applications from scratch, Java has emerged as a key player in the data science sector in recent years. Those Java Virtual Machines, which offer a strong and effective framework for well-liked big data tools like Hadoop, Spark, and Scala, are mostly to blame for this.
