The Robust Guide on Python for Data Science

For the data analytics domain, python is a mandatory learning programming language for all web developers. With the increasing demand for IT professionals, the IT industry is booming up to an extent. Python is one of the preferable coding languages that is used for data-driven development. This blog will help to learn the basics and its library. Now, before proceeding to further details, let’s know some details of data science before dig into the python for data science concept:-

What is data science?

Data science has raised as a career path for several skilled experts. The data science can be used as the problem-solving as it provides insight and outsight solutions that are driven by the data. There is a misconception about data science, but it can be clarified with the help of data science that is described below:

Data science cycle

It starts from recognizing the business requirements that are used to prepare the information for model building and expending the insight finally. The process of data science is handled by several experts, such as data engineers, data analysts, and data scientists. The role of them depends upon the company’s size, but sometimes the whole process is done by a single expert.

Why is there a need for python for data science?

Python is the best programming language for data science because of the following reasons that are listed below:

  • Python is a flexible, free, and powerful open-source coding language.
  • It reduces developing time in half because of its simplicity and readable syntax.
  • With the help of python, you can carry out data analysis, manipulation, and visualization.
  • Python offers libraries for scientific computations and other machine learning applications.

Basic terminology of python for data science:

Now, we will discuss the basic terminologies that are used in python for data science. So that you can easily understand the use of python in web developing: 


This is referred to as a reserved memory location that is used to save the values. For the python coding language, one does not require to declare the variables before writing them in the programming, or even it does not require to declare their types. 

Data Types

It supports various data types that used to define the various operations which are possible for storage methods and variables. The data types can involve:- List, Tuples, Dictionary, Numeric, Strings, and Sets.


This helps to manage the value of the operands. The python’s operators involve:- Comparison, Logical, Membership, Assignment, Bitwise, and Identity.

Conditional Statements

It helps to implement various statements that are based on various conditions. There are basically three conditional statements:- Elif, If, and Else.

These are used to repeat certain work through a coded program. The loops in python are of three types:- For, While, and nested loop.


These are used to separate the codes into useable blocks that allow you to order the programs, and make it readable, reusable, and saves time.

Libraries of python

This is the section where the actual picture of python for data science comes into account. Python has several libraries for scientific analysis, visualization, computations, etc. and few of them are described below:


It is the central library of python for data science that refers to ‘numerical python’. This is utilized for scientific or complex computations, that has n power dimensional array objects. Besides this, it offers various tools for integrating C++, C, etc. This also uses for multi-dimensional generic data where one can process several special functions and Numpy operations.


It is an essential library of python for data science as it can be used for data analysis and data manipulations. It is suitable for various data like unordered and ordered time series, tabular, matrix data, and much more.


It is a powerful library that is used for visualization in python as python shell, GUI toolkits, scripts, and web application servers. One can use different plots and know-how this plot works.


It is a library of statistical plotting. You can use Matplotlib for 2D pictures, and seaborn can add beautiful styles to it and draw a high-level interface graphics.
