The following are the two data structures in Pandas <\/p>\n\n\n\n

Series \u2013 It handles and stores data in one-dimensional data.<\/p>\n\n\n\n

DataFrame \u2013 It handles and stores two-dimensional data.<\/p>\n\n\n\n

Data Visualisation libraries<\/strong><\/h2>\n\n\n\n

Data visualization is the graphic representation of data. It involves producing images that communicate relationships among the represented data to viewers of the images\u00a0<\/p>\n\n\n\n

Matplotlib<\/strong><\/h2>\n\n\n\n

Matplolib is another useful Python library for Data Visualization. Descriptive analysis and visualizing data is very important for any organization. Matplotlib provides various methods to visualize data more effectively. Matplotlib allows us to quickly make line graphs, pie charts, histograms, and other professional-grade figures. Using Matplotlib, one can customize every aspect of a figure. Matplotlib has interactive features like zooming and planning and saving the Graph in graphics format.<\/p>\n\n\n\n

Seaborn<\/strong><\/h2>\n\n\n\n

Seaborn is a library for making statistical graphics in Python<\/a>. It is built on top of matplotlib and closely integrated with pandas data structures.<\/p>\n\n\n\n

It is specialized with support for using categorical variables to show observations or aggregate statistics. Seaborn can also do automatic estimation and plotting of linear regression models for different kinds of dependent variables.<\/p>\n\n\n\n

Bokeh<\/strong><\/h2>\n\n\n\n

Bokeh is a Python library for interactive visualization that targets web browsers for representation. This is the core difference between Bokeh and other visualization libraries. Bokeh can produce elegant and interactive visualization like with high-performance interactivity over very large or streaming datasets. Bokeh can help anyone who would like to quickly and easily create interactive plots, dashboards, and data applications.<\/p>\n\n\n\n

Plotly<\/strong><\/h2>\n\n\n\n

The Plotly Python library is an interactive, open-source plotting library that supports over 40 unique chart types covering a wide range of statistical, financial, geographic, scientific, and 3-dimensional use-cases.<\/p>\n\n\n\n

Machine learning & Deep Learning libraries <\/strong><\/h2>\n\n\n\n

Machine learning is largely based upon mathematics. Specifically, mathematical optimization, statistics, and probability. Python for Data Science libraries help researchers and mathematicians who are less equipped with developer knowledge to easily do machine learning easily<\/p>\n\n\n\n

Tensorflow<\/strong><\/h2>\n\n\n\n

TensorFlow is an end-to-end open-source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries and community resources that lets researchers push the state of the art in ML and developers easily build and deploy ML-powered applications<\/p>\n\n\n\n

How to import a library module before using it.<\/strong><\/h2>\n\n\n\n

To make use of the functions in a module, you\u2019ll need to import the module with an import statement. An import statement is made up of the import keyword along with the name of the module. In a Python file, this will be declared at the top of the code<\/p>\n\n\n\n

Use import..<\/strong>to load a library module into a program\u2019s memory.<\/p>\n\n\n\n

import pandas<\/strong><\/p>\n\n\n\n


Create an alias for a library module when importing it to shorten programs.<\/strong><\/p>\n\n\n\n

Use import..as..<\/strong>to give a library a short alias<\/em> while importing it.<\/p>\n\n\n\n


import pandas as pd<\/em><\/strong>
Import specific items from a library module to shorten programs<\/em><\/strong><\/p>\n\n\n\n

Use from..import..<\/strong> to load only specific items from a library module. from sklearn.preprocessing import imputer<\/strong><\/p>\n\n\n\n

This is how you use libraries<\/p>\n\n\n\n

That’s all about some of the most popular Python libraries for Data Science, Machine Learning, and Artificial Intelligence.
