For someone who is embarking on the path to data science, among the first things that he/she will face is the choice of programming languages to learn. There are several programming languages one can choose from, but not knowing the right choice can become a problem. Prior to enrolling in any course offered by the Best Institute for Data Science, some information on the same is very helpful.
Why Programming Language Choice Matters
Data science includes the steps of collecting, processing, analyzing, and modeling data, and the programming language that you use makes a difference in how effective you are at performing each step. Some programming languages are more geared towards statistical analysis, while other programming languages help in developing applications. Using the appropriate language will allow you to be more efficient and have an easier learning experience.
Python: The Most Popular Choice
Among all the programming languages being used in data science, none has become as popular as Python has. This is because not only does it allow you to easily write readable code without having any previous experience with coding, but it also provides an extensive library for data science work. Libraries such as Pandas, Numpy, matplotlib, seaborn, and scikit-learn have been developed for this purpose.
Apart from being simple, Python is also considered the best language for deep learning and AI because of frameworks such as TensorFlow and PyTorch. Because of its flexibility, Python is always suggested as the first programming language one should learn when pursuing data science.
R: The Statistician's Favorite
The R programming language was developed solely for statistical computations and, hence, is quite ideal for people whose work revolves around statistical modeling and research. Its strengths lie within its powerful data visualization packages, such as ggplot2, and it is popularly used in areas such as bioinformatics, economics, and social sciences, among others.
Even though R has less of a general-purpose environment in comparison to Python, it is widely used by statisticians and researchers who require sophisticated statistical tools, which are at times simpler to use in R than in any other language.
SQL: The Language of Databases
Although SQL isn’t technically considered a programming language, it is extremely important when it comes to dealing with data. Business data exists mostly within relational databases, and SQL is the most common language that is used to query, filter, and manage such data. It is rare to find a position within data science that does not require a good level of proficiency in SQL.
Other Languages Worth Knowing
Whereas Python, R, and SQL are all that you need for data science, some other programming languages should be noted based on your career path.
- In fact, Java and Scala are popular programming languages in big data environments. Big data requires the use of some tools, like Apache Spark and Hadoop.
- Python is a relatively old programming language with many libraries, but Julia is an emerging language known for its fast computations in numerical calculations.
- It may be used in some machine learning applications, but only as a hidden tool because C++ is hardly ever chosen by beginners to start programming.
So, Which Language Should You Learn First?
For those who are beginners, however, Python still comes out as the best place to begin. With its simplicity, active communities, and diverse libraries, it is undoubtedly the language that will give an aspiring data scientist the best chance at developing their career. Once you have become acquainted with Python, your next step should be to learn SQL.
In case your professional route will be more oriented towards research and statistics, then getting familiar with R, along with Python, could also be helpful. Once you gain experience, you could get to know more languages depending on your job profile and area of expertise.
Final Thoughts
Picking the appropriate programming language is one of the key things to consider when starting out in the field of data science, and with Python being simple and flexible enough, it is definitely the way to go. With data playing an ever-increasing role in decision-making and security, many people are venturing into other industries.
If you want to merge your technical knowledge with the security skills that are required in today’s world, you should think about taking the Cybersecurity with AI Course.
