Why Python Programming Language is Important for Data Science?

posted in: Data Science, Python | 0

Python For Data SciencePython is a high-level, interpreted, open-source, programming language with a great object-oriented programming strategy. It’s one of the most widely used programming languages among data scientists for a wide range of projects and applications. Python offers several tools for dealing with statistics, arithmetic, and scientific functions. It has excellent libraries for Data Science applications. In this blog we will discussed about “Why Python Programming Language is Important for Data Science?”

Python’s popularity in the scientific and research fields stems from its ease of use and straightforward syntax, which makes it simple to learn even for persons without an engineering background. It’s also better for rapid prototyping. Join Python Training in Chennai to enhance your programming skills in python domain.

Deep learning frameworks available with Python APIs, in addition to scientific packages, have made Python very productive and versatile, according to engineers from academia and industry. Deep learning Python frameworks have evolved significantly, and they are rapidly improving. Here we discuss about Python for Data Science.

Python is also preferred by ML scientists in terms of application domains. Developers favored Java for areas such as fraud detection algorithms and network security, while Python was chosen for applications such as natural language processing (NLP) and sentiment analysis because it offers a large library of libraries that help solve complex business problems quickly and build strong systems and data applications.

The most widely used data science libraries are:


Numpy is a Python package that contains mathematical functions for dealing with huge arrays. It has Array, Metrics, and Linear Algebra methods and functions.

Numerical Python is referred to as NumPy. It has a lot of handy features for n-arrays and matrices operations in Python. On the NumPy array type, the library supports vectorization of mathematical operations, which improves performance and speeds up execution. NumPy makes working with big multidimensional arrays and matrices a breeze.


Pandas is a Python toolkit for data manipulation and analysis that is widely used. Pandas has capabilities that may be used to manipulate vast amounts of structured data. Pandas are the simplest way to undertake analysis. It supports huge data structures as well as numerical tables and time series data manipulation. Pandas is an excellent data wrangling tool. Pandas is a data manipulation, aggregation, and visualization tool that is simple to use. Pandas has two different kinds of data structures:

It manages and stores data in a one-dimensional format.

DataFrame: It is used to store and handle two-dimensional data.

Matplotlib: Another important Python module for data visualisation is Matplotlib.

For any company, descriptive analysis and data visualisation are critical. Matplotlib provides a number of methods for more effectively visualising data. Matplotlib enables the creation of line graphs, pie charts, histograms, and other professional-grade figures in a matter of seconds. Every feature of a figure can be customised with Matplotlib. Matplotlib has interactive capabilities such as zooming and planning, as well as the ability to save the Graph in graphical format.

Scipy: Another well-known Python package for data research and scientific computing is Scipy. Scipy is a programming language for scientific mathematics and computers that has a lot of features. Optimization, interpolation, linear algebra, integration, special functions, signal, FFT, and image processing, ODE solvers, Statmodel, and other activities common in research and engineering are all covered by SciPy sub-modules.

Scikit: Sklearn is a Python library for machine learning developed by Scikit-Learn. Sklearn includes a variety of machine learning algorithms and functions. NumPy, SciPy, and Matplotlib are the foundations of Sklearn. Sklearn delivers easy-to-use data mining and data analysis tools. It gives consumers access to a set of common machine learning algorithms via a standardized interface. Scikit-Learn aids in the rapid implementation of popular algorithms on large datasets and the solution of real-world issues.
