Best Tutorials To Learn Popular Python Data Science Libraries

Python is the most widely used programming language today. When it comes to solving data science tasks and challenges, Python never ceases to surprise its users. Most data scientists are already leveraging the power of Python programming every day.

Here today, We have curated a list of the best Python libraries for Data Science and its periphery, when to use them, their advantages, and the best tutorials to learn them.

1. Pandas

It is an open-source Python package that provides high-performance, easy-to-use data structures and data analysis tools for the labeled data in Python programming language. Pandas stand for Python Data Analysis Library Who ever knew that?

It is one of the best tools for data wrangling or munging. It is built for quick and easy data manipulation, reading, aggregation, and visualization.

This library takes data in a CSV or TSV file or a SQL database and creates a Python object with rows and columns called a data frame. The data frame is very similar to a table in statistical software, say Excel or SPSS.

2. NumPy

NumPy (Numerical Python) is a perfect tool for scientific computing and performing basic and advanced array operations.

It enables a higher speed of computation as long as most of the operations work on arrays and matrices, along a large set of high-level mathematical functions to operate on these arrays.

3. SciPy

As the name suggests, SciPy is mainly used for its scientific functions and mathematical functions derived from NumPy.

Some useful functions which this library provides are stats functions, optimization functions, and signal processing functions.

To solve differential equations and provide optimization, it includes functions for computing integrals numerically

Some of the applications that make SciPy important are Multi-dimensional image processing, the ability to solve Fourier transforms, and differential equations.

Due to its optimized algorithms, it can do linear algebra computations very robustly and efficiently.

4. TensorFlow

TensorFlow is a free and open-source software library for machine learning. It can be used across a range of tasks but has a particular focus on training and inference of deep neural networks. TensorFlow was developed by the Google Brain team for internal Google use.

One of the most developed websites amongst all libraries is of TensorFlow Giants like Google, Coca-Cola, Airbnb, Twitter, Intel, DeepMind, everyone uses TensorFlow!

This library is quite efficient when it comes to classification, perception, understanding, discovering, predicting, and creating data. It’s one of the best Python libraries for Data Science and Machine Learning enthusiasts.

5. Keras

It’s an open-source software library that provides a Python interface for artificial neural networks. Keras acts as an interface for the TensorFlow library.

Using this library, you can determine percentage accuracy, compute loss functions, create custom function layers, built-in data and image processing, write functions with repeating code blocks, and much more.

6. Scikit-learn

This is an industry standard for data science projects based on Python.

Scikits is a group of packages in the SciPy Stack that were created for specific functionalities – for example, image processing Scikit-learn uses the math operations of SciPy to expose a concise interface to the most common machine learning algorithms

Data scientists use it for handling standard machine learning and data mining tasks such as clustering, dimensionality reduction, and classification. It comes with quality documentation and offers high-performance

8. Plotly

Plotly is a free and open-source data visualization library. Data Scientists love this library because of its high quality, publication-ready, and interactive charts Boxplots, heatmaps, and bubble charts are a few examples of the types of available charts.

It is one of the finest data visualization tools available built on top of the visualization library. So if you are looking to explore data or simply want to impress your stakeholders, plotly is the way to go!

9. Scrapy

The next known Python library for data science is Scrapy. This library is one of the most popular, fast, open-source web crawling frameworks written in Python. It is commonly used to extract the data from the web page with the help of selectors based on XPath.

Scrapy helps in building crawling programs (spider bots) that can retrieve structured data from the web.

10. Seaborn

This library is based on Matplotlib that provides a high-level interface for drawing attractive and informative statistical graphics.

Putting it simply, seaborn is an extension of Matplotlib with advanced features Matplotlib is used for basic plotting; bars, pies, lines, scatter plots, and stuff, seaborn provides a variety of visualization patterns with less complex and fewer syntax.

11. Statsmodels

Although data scientists are generally hesitant to approach statistical modeling methods, Statsmodels is a must-know library.

Besides offering important implementations of algorithms like ANOVA and ARIMA that standard machine learning libraries like Scikit-Learn do not have, perhaps what is most valuable about Statsmodels is the sheer level of detail and information it provides.

Beyond incredibly detailed statistical modeling, Statsmodels also offers a variety of helpful data features and metrics.

13. NLTK

NLTK (Natural Language Toolkit) mainly works with human language more than computer language to apply natural language processing (NLP).

It contains text-processing libraries with which you can perform tokenization, parsing, classification, stemming, tagging, and semantic reasoning of data.

14. PyTorch

PyTorch is a framework that is perfect for data scientists who want to perform deep learning tasks easily. The tool allows performing tensor computations with GPU acceleration.

PyTorch is based on Torch, which is an open-source deep-learning library implemented in C, with a wrapper in Lua.

15. Beautiful Soup

Beautiful Soup is yet another Python library for scraping Web content.

Unlike Scrapy which you have to develop your own “spider” and go back to command-line the and run it, Beautiful Soup allows you to import its functions and use them in-line. Therefore, you could even use it in your Jupyter notebooks.
