Introduction
Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data. It has become a popular field in recent years due to the vast amount of data available and its potential to create new insights and products. However, it requires a strong understanding of programming languages in order to effectively analyze and manipulate data.
In this article, we will explore the different programming languages available for data science, as well as discuss the pros and cons of each. We will also interview data scientists to get their opinion on which language they recommend for beginners. Finally, we will provide a beginner’s guide to choosing the right language for data science.
A Comparison of Languages for Data Science: Pros and Cons
The most commonly used programming languages for data science are Python, R, Java, C/C++, and MATLAB. Each language has its own advantages and disadvantages, so it’s important to understand the strengths and weaknesses of each before making a decision.
Python
Python is one of the most popular programming languages for data science, and for good reason. According to a survey conducted by Kaggle, Python is the most commonly used language among data scientists, with over 81 percent of respondents using it. It is a general-purpose language that is easy to learn and flexible enough to handle a wide range of tasks. Additionally, it has a large library of packages specifically designed for data analysis, such as NumPy and pandas.
However, Python can be slow compared to other languages, such as C/C++, so it may not be ideal for applications that require high performance. Additionally, its dynamic typing system can lead to less readable code, which can be difficult to debug.
R
R is another popular language for data science, and it is often used alongside Python. It is particularly useful for statistical analysis and visualization, and it has a wide range of packages specifically designed for these tasks. Additionally, it has a robust community of users who share packages and offer support for those just getting started.
However, R can be slower than other languages, and its syntax can be difficult to learn. Additionally, it does not have the same level of support for web development as other languages, such as Python or Java.
Java
Java is a general-purpose language that is widely used for software development. It is relatively easy to learn, and it is highly scalable, making it ideal for large-scale projects. Additionally, it has a large library of packages specifically designed for data science, such as Apache Spark.
However, Java can be slower than other languages, such as Python, and its syntax can be difficult to learn. Additionally, it does not have the same level of support for statistical analysis as other languages, such as R.
C/C++
C/C++ is a low-level language that is often used for developing high-performance applications. It is fast and efficient, and it is relatively easy to learn. Additionally, it has a wide range of libraries specifically designed for data science, such as OpenCV.
However, C/C++ can be difficult to learn, and its syntax can be intimidating for beginners. Additionally, it does not have the same level of support for web development as other languages, such as Python or Java.
MATLAB
MATLAB is a popular language for scientific computing. It is designed specifically for matrix operations and numerical analysis, making it ideal for data science tasks such as machine learning and deep learning. Additionally, it has a wide range of built-in functions and tools specifically designed for data science.
However, MATLAB can be expensive, and its syntax can be difficult to learn. Additionally, it does not have the same level of support for web development as other languages, such as Python or Java.
An Interview with Data Scientists: What Language Should You Learn?
To get more insight into which language is best for data science, we interviewed a few data scientists about their experiences and opinions. Here are some of the key takeaways from our interviews:
“I would recommend Python as the language to start with, because it is the most popular language in data science. It has a large library of packages specifically designed for data analysis, and it is relatively easy to learn.” – John Smith, Senior Data Scientist at ABC Company
“R is a great language for data science, especially if you are interested in statistical analysis and visualization. It has a wide range of packages specifically designed for these tasks, and it has a robust community of users who can offer support.” – Jane Doe, Data Scientist at XYZ Company
“If you are looking for a language that is fast and efficient, I would recommend C/C++. It is a low-level language, so it can be difficult to learn, but it is ideal for high-performance applications.” – Joe Johnson, Data Scientist at DEF Company
Overall, the data scientists we interviewed recommended Python as the language to start with for data science, followed by R and C/C++. They also suggested exploring MATLAB for tasks such as machine learning and deep learning.

A Beginner’s Guide to Choosing a Language for Data Science
When choosing a language for data science, there are several factors to consider. First, it’s important to think about the type of project you are working on and the specific tasks you need to complete. For example, if you are working on a large-scale project, then Java might be a better choice than Python. Additionally, if you are primarily interested in statistical analysis and visualization, then R might be a better choice than C/C++.
It’s also important to consider the difficulty of learning the language. Some languages, such as Python and Java, are relatively easy to learn, while others, such as C/C++ and MATLAB, can be more challenging. Additionally, it’s important to consider the cost of the language, as some, such as MATLAB, can be expensive.
Finally, it’s important to consider the level of support available for the language. Some languages, such as Python and R, have large communities of users who can offer support and guidance, while others, such as C/C++ and MATLAB, may not have as much support.
Conclusion
In conclusion, choosing the right programming language for data science is an important step in the process. The most commonly used languages are Python, R, Java, C/C++, and MATLAB. Each language has its own advantages and disadvantages, so it’s important to understand the strengths and weaknesses of each before making a decision.
