Programming languages are the tools developers use to create software and computer programs. These best programming languages for data science consist of rules, instructions, and syntax, enabling programmers to craft computer code that executes various tasks.

Programming languages are in demand for various applications, from software development and web design to machine learning, data science, and artificial intelligence. Each programming language has its own rules, which developers must abide by when writing programs using that particular language.

Role of programming languages in data science

Programming languages are essential tools in data science, enabling various tasks like cleaning and analyzing raw data, modeling, visualization, and deployment of machine learning models. Here are a few key functions the best programming language performs for data science:

  • In-demand data science programming languages, like Python and R, offer powerful data cleansing and manipulation libraries. These tools enable data scientists to quickly clean and prepare their datasets for analysis.
  • Analysis of statistical Data Programming Languages like R is specifically tailored for statistical analysis. They offer tools for testing hypotheses, regression analysis, hypothesis testing, and more.
  • Python has become the go-to language for machine learning due to the availability of powerful libraries like Scikit-learn, TensorFlow, and PyTorch. These tools enable data scientists to construct and train models using these powerful libraries quickly.
  • Deployment data science programming languages like Python and Java pay handsome salaries, so these are widely used for deploying machine learning models in production. These programming languages enable data scientists to design efficient and scalable systems that deliver predictions with precision.

When selecting the best programming language for data science, your goals and tasks must be considered. Here are the different languages one can learn in a data science program:

  • Python

Python is one of the world’s most widely-used programming languages for data analysis. It provides a wealth of tools and libraries for data exploration, machine learning, and visualization; these include NumPy, Pandas, and Matplotlib. 

Python offers a straightforward syntax to comprehend and write, making it ideal for newcomers. Python extends object-oriented languages, supporting inheritance, encapsulation, and polymorphism.

  • R

Data science professionals often rely on R as a programming language. It offers various data manipulation and modeling programs. R is free and open-source software, meaning anyone can download, use, and modify it without cost, making it one of the most data science programming languages in demand. This ensures that everyone can benefit from its capabilities.

R, a statistical computing program designed specifically for statistical computation, offers various analytical tools to analyze data, such as nonlinear and linear modeling, time series analysis, and clustering.

  • SQL

SQL is a language designed to manage the querying of relational databases. Data scientists often rely on databases for analysis and information access, so familiarity with SQL is essential. SQL allows developers to define, modify and delete database structures like indexes, tables, and constraints. 

They can also insert, update, remove, and query information within the database. SQL boasts a straightforward syntax to learn, making it ideal for those just starting in programming.

  • C/C++

C and C++ are powerful, flexible programming languages for creating applications, system software, and embedded systems. C/C++ is an open-source language that can be compiled and run on various platforms such as Windows, Linux, and Mac OS. 

C is a procedural programming language focusing on data manipulation procedures and functions. On the other hand, C++ is an object-oriented programming language that supports objects and classes.


MATLAB is a high-level data science programming language for numerical computation, visualization, and programming. It has become heavily utilized in data science fields like signal processing, machine learning, and image analysis.

MATLAB provides direct access to information from external sources such as images (.jpg, PNG), audio files (.mp), and actual-time files from JDBC or ODBC via its built-in functions like audioread for reading audio files and imread for reading images from external sources. 

Matlab has an integrated feature of Simulink that enables us to simulate control systems and observe their behavior in real-time. You can create any system using code or construction blocks, then view its operation using different built-in tools. 

  • Scala

Scala is a programming language designed to work with the Java Virtual Machine and is renowned for its scalability and performance. It’s often used to construct large systems as well as distributed processing.

Scala offers functional and object-oriented programming styles, enabling you to combine these powerful techniques for writing clean, reliable code. This combination provides maximum power when crafting code. This helps detect errors early in the compilation phase rather than at runtime, potentially saving much time and energy when debugging or testing.

  • Go

Go has its roots in many programming languages, especially the C Language. Composed of standard libraries and external third parties provided by organizations and individuals alike, the Go Project fosters creativity within computer programmers worldwide.

You can generate binaries for your application with all dependencies included, eliminating the need to install the runtimes required for running it. This simplifies installation and updates for thousands of programs across various OSes and processor designs – an impressive step in software development.

  • Julia

Julia is a relatively new programming language quickly gaining traction among data scientists. Julia has been designed for speed, with capabilities comparable to C or Fortran. This makes Julia an ideal choice for data analysis and machine learning tasks.

Julia makes writing code an interactive experience, making it simple to experiment with new ideas. Furthermore, Julia has been designed with dynamic typing so you can write code quickly without worrying about type declarations.

  • SAS

SAS stands for Statistical Analysis Systems. This top programming language for machine learning utilizes procedures for various tasks like data analysis and management. With SAS, you can generate both text-based and graphic presentation output.

SAS simplifies information management by offering cleaning, transformation, and integration tools, enabling you to manage data from various sources easily. SAS offers a comprehensive suite of predictive and statistical analytics tools, such as regression analysis, time series analysis, and machine-learning algorithms.

  • Java

Java is a widely-used general-purpose programming language across various industries. It’s ideal for creating software that processes and analyzes large databases. Java is an object-oriented top programming language for machine learning, designed for modularity and reusability while being easy to manage. Java provides automatic memory management, so the programmer does not need to take special care in managing it.
