Top 10 most helpful Python libraries for data science

Data science is a multidisciplinary approach to extracting actionable insights from large and ever-increasing collected data. It encompasses preparing data for analysis and processing, performing advanced data analysis, and presenting the results to reveal patterns and enable stakeholders to draw informed conclusions. Machine learning is one of the effective technologies to make precise predictions through the data obtained from data science and sports numerous use cases. Machine learning finds prominent applications with Python.

Python is a general-purpose programming language that is becoming ever more popular for data science. It has been used in data science, IoT, AI, and other technologies, which has added to its popularity. Companies worldwide are using Python to extract insights using the algorithms from their data.

If you track the trends over the past few years, you will notice that Python has become the programming language of choice, particularly for data science.

But the question is–

What makes Python so Special for Data Scientists?

Just like the human body consists of multiple organs for multiple tasks and a heart to keep them running, similarly, the core Python provides us with the easy-to-code, object-oriented, high-level language.

There are different libraries for each type of job like Math, Data Mining, Data Exploration, and visualization.

It is of utmost importance that every library has its specific functions and features. These are the core libraries, and these won’t change overnight.

Let dive into the Top 10 most helpful Python libraries for data science.

1. Scrapy

It is one of the most popular Python data science libraries. It helps develop spider bots(crawling spiders) that can fetch structured data from the web or app—for instance, URLs, contact info. In addition, it’s a great tool for retrieving data used in python machine learning models.

Most developers use it for gathering data from APIs(An API is a set of definitions and protocols for building and integrating a website or software). This is full-fledged framework follows the Don’t repeat yourself principle in the design of its interface. So, it helps developers to write universal code that can be reused for developing large-scale crawlers.

2. BeautifulSoup

It is a great parsing library in Python that enables web scraping from HTML or XML pages. BeautifulSoup automatically detects encodings and handles HTML pages even with special characters.

That can help to navigate a parsed document and find what we need and makes it faster to extract the data from the pages. BeautifulSoup gets first place among popular Python parsers like iXML and HTML5lib, allowing developers to try different parsing strategies.

If you want to collect data that are available on the website but not via CSV or API, BeautifulSoup can help you scrape it and arrange it into the format you want.

3. NumPy

NumPy stands for NUMerical PYthon. If you want to create a scientific computing tool and perform basic and advanced array operations, then NumPy is an ideal tool. For example, we know that Machine learning algorithms are computationally complex and require multidimensional arrays. But this library offers many valuable features performing operations on n-arrays and matrices in Python. It also supports a vast, multifaceted collection of objects and tools to work with them.

4. SciPy

NumPy stands for NUMerical PYthon. If you want to create a scientific computing tool and perform basic and advanced

SciPy is known for its optimization, interpolation, and integration. Therefore, it is an important machine learning library for app developers, who want to focus on statistics, integration, linear algebra, and optimization. Furthermore, since it is built with NumPy, the arrays are benefitted from the use of NumPy.

In addition to this, SciPy uses NumPy for solving complex mathematical functions. Furthermore, it utilizes the NumPy arrays as basic data structures and is often used as a task in scientific programming.

5. Pandas

The proficiency of Pandas spans data exploration, visualization, and analysis. It is an open-source package. It enables the easy performance of data analysis and manipulation in Python. In addition to this, Pandas also offers flexible and fast data structures, making it easy to work with Relational and structured data. Pandas in Python is a two-dimensional size-mutable structure. It is a popular library with Python, given its versatility and efficiency in handling data.

6. Matplotlib

Matplotib in Python features data visualization and numerical extension. Therefore, it is one of the most viable open source alternatives for embedding plots in GUI applications. Matplotib is built on the NumPy arrays, which are designed to operate with SciPy. In addition to this, the Python library enables visual access to voluminous data and turns it into digestible visuals. It consists of various plots such as bar, line, histogram, scatters, etc.

7. Plotly

Plotly offers online graphing, statistical analysis, analytics, three-dimensional charts, financial charts, and more. It is a more sophisticated data visualization technique tool, which is used to build elaborate plots more efficiently. It allows endless customization to python developers for making plots rich in meaning and interpretable.

Plotly is also known for its interactivity. The open-source library provides tools for data simplicity and data visualization. It enables the detection of anomalies in huge piles of data, which can be helpful to ensure a high level of accuracy.

8. Seaborn

Seaborn is one of the most popular python libraries and is built on Matplotib. It is an amazing library to visualize statistical graphics that are plotting in Python. It offers default styles and numerous color palettes for crafting statistical plots in an attractive manner. Seaborn provides dataset oriented API for determining relationships between multiple variables.

The Python library offers an automatic estimation as well as the plotting of linear regression plots. It also underpins high-level abstractions of multi-plot grids.

9. Scikit Learn

Scikit Learn is among the robust and useful python libraries for machine learning. It offers a selection of useful tools for statistical modeling and machine learning. It includes regression, classification, dimensionality reduction, and clustering through a consistent interface. Other than focusing on loading, summarising data, and manipulating, Scikit Learn is concentrated on data modeling.

Scikit Learn combines the predictions for numerous multiple supervised models. It can determine useful attributes for creating supervised models.

10. PyCaret

PyCaret is known as an open-source Python library, which enables Python developers to prepare data and deploy data models within minutes. It is a business-ready solution and enables efficient prototyping. The Python library is easy to interpret and uses machine learning technology. It also helps perform end-to-end experiments with fewer codes to save the size of the app.

It encourages productivity. Since less time is spent on coding and your Python team can concentrate on their business problems.

Key Takeaway

If you are looking forward to kickstarting your project focused on machine learning, these top ten python libraries will come to your resort. However, before the selection of the right Python library for your project, you should analyze your project requirements quite well. This analysis will help you pick out the features that you should look for in a Python library.

Alternatively, you can seek consultation from an expert python development company.
