The emerging field of Data Science is wildly calling and is not easy to give up on, just like that! If you are a non-coder, a beginner, or someone from a non-CS/ non-IT background, you probably might think- after all, how much coding is required for data science?
Well, the absolute answer to “Is coding required for Data Science” is YES! While a very high level of coding like the software developers is not essential for Data Science, however, if you ask me- “How much coding is needed for data science?” the answer will deviate from one job role to another.
Well, the golden thumb rule is that coding is not required to get started in Data Science. However, you can learn it in the process of mastering Data Science for specific tasks alone. But coding is always a plus!
Btw, Why is coding required in Data Science?
Data Science requires coding when it comes to
Basically one needs to have good programming knowledge when it comes to the following implementations:
- Machine Learning Libraries
- Data Transformation
- Statistical Packages
- Greater control over data
- Version Control
Machine Learning techniques go hand-in-hand with Data Science. And when talking about machine learning, it does involve a lot of coding.
Without at least some knowledge of coding languages, working with machine learning libraries or even replacing them would be too hard! Therefore, we have to make our hands dirty with coding to integrate machine learning libraries in data science.
Transforming data from one form to another, converting data types, removing duplicate data, or even enriching data to enhance its usability are all the Data transformation techniques that can be well-managed with better coding skills. Data transformation tools and packages like Pandas and Tidyverse assist in cleaning the raw data and delivering clear insights.
Statistical Analysis and calculations help Data Scientists with more accurate results. Tools ease these Data Science calculations and produce better results in less time. However, these tools incorporate at least a basic amount of coding. So, that is what makes coding know-how a requisite skill for Data Scientists.
Coding languages are versatile. It gives more flexibility and ease in reading and managing data. It improves your control over data and making sense of the available data becomes simpler. Specific conditions and the logic applied with coding, increase the readability.
Moreover, you can go ahead with script automation and save time while augmenting interest.
The importance of version control cannot be ignored when it comes to big projects. Version control records the changes and allows better control over the multiple programmer modifications made to the project. This process demands your coding proficiency! Another reason that makes coding requisite to be a Data Scientist.
So, what programming languages are used in Data Science?
All that said, which are the programming languages that you should be focusing on?
- Structured Query Language
Let’s dig deep and understand, why and how these programming languages become vital while you accelerate your career in Data Science.

Python’s ease of use and simple syntax make this popularly used programming language a warm and easy-to-learn coding base for even beginners. Python has a powerful collection of libraries and is most widely used in machine learning, data analysis, and data visualization.
Is learning Python in 2022 worthwhile?
- Widely used programming languages for scripting, data proficiencies, and automation.
- Unlimited access to many libraries and frameworks
- Wide range of professional opportunities
- Python developers’ compensation is significantly greater than that of other developers
Some of the use cases of Python:
- Getting data from an API
- Creating a dataset
- Querying non-relational data from MongoDB
- Performing data analysis
- Executing data visualization
R is an ideal tool when it comes to data wrangling. And, it allows the usage of several preprocessed packages making data wrangling a lot easier. Most importantly, R presents a wide variety of statistics-related libraries. So, it delivers a favourable environment for statistical computing and design.
Above all, R is a programming language created by statisticians for statistics, specifically for working with data.

Some use cases of R in Data Science:
- Analytics: to identify patterns and build practical models.
- Great support & libraries
- Visualizing Data
- Transforming Data
- Machine learning
SQL is one of the most powerful programming languages used for extracting and communicating various data types from databases. Relational Database Management or SQL is an integral part of Data Science. While multiple industries are now driving their product management with NoSQL, SQL still remains a perfect choice for numerous CRMs, business intelligence tools and in-office operations.
What is the importance of SQL in Data Science? What do we use SQL for?
- For data wrangling and preparation
- To handle structured data
- Most importantly, for querying databases
- To carry out data analytics with the data that is stored in relational databases like Oracle, Microsoft SQL, MySQL

Git is a free and open-source distributed version control system, for tracking changes in any set of files. That said, Git is the most important tool for all software developers. And owing to its ability to track every change, Git is becoming an indispensable part of data scientists’ careers too. Data Scientists and analysts can employ its Version Control System (VCS). With the help of Git, they can work on the same data project together.
What is Git used for in data science?
- To track code and file changes
- Version control
