Nowadays, everyone is familiar with Python as the language used in information technologies and one of the most popular languages in data science and machine learning fields. Amongst these, they include that Java is easier to code in, java is an object-oriented language, java is a high-level language, and last but not least, java comes with a number of packages readily available for many applications. It has attracted over 137,375 libraries for membership, and it is in the introduction of technology among the leading organizations.
Python is beneficial for data science because it allows one to access several libraries for data pre-processing, analysis, visualization, machine learning, and deep learning. In this article, we will explore the essential Python libraries for data manipulation.
From this, it can be concluded that NumPy is one of the most trending open-source packages available in Python libraries and has also been hugely preferred for scientific distributions. This set of mathematical functions enables many computations, mainly when applied in operations encompassing large and complex data, including large matrices, for instance, used in linear algebra, in which it shines depending on the specific application. It takes up less memory space and is more efficient than a list, for it needs less memory space.
NumPy, otherwise known as Numerical Python, was developed as an open-source project conceived to unleash an efficient vector computing entity in Python. Initially conceived in mid-2005, it builds upon Numeric and numarray, which were initiated in late 1995. In turn, it is necessary to recognize that NumPy has virtually one of the main advantages: it is released under terms of the modified BSD license, and its usage is free.
Some of the tools that are common in data analysis include pandas. This is one of the popular Python libraries. They provide strategies to address similar issues that often emerge, including managing big data, preparing it, and pre-processing data. They also consist of simple data modeling and analysis tools as they could be more precise first-order coding. According to the information provided under the ‘Home’ tab on their homepage, some advantages associated with the specification of pandas include speed, flexibility, and powerful operation on data, which makes it powerful in data analysis and manipulation.
Matplotlib is a powerful Python library for creating static pictures and dynamic and animated graphs and plots in Python. There are also third-party packages that are compatible with Matplotlib for extending and enriching its capabilities, some of which are advanced plotting tools (Seaborn, HoloViews, ggplot, etc.).
Matplotlib is designed to emulate MATLAB in terms of performance, with the bonus of being a Python library. It also has the advantage of being free, and the public can access its source code without payment. It allows users to display data with different kinds of plots, such as scatter plots, histograms, bar charts, error charts, and box plots. Additionally, all the visualizations contained herein can be produced with a few lines of code.
A widely used Python library for creating visually attractive and informative statistical graphics, Seaborn serves as an advanced tool for developing beautiful and practical charts that are vital for understanding and analyzing data. This library has a strong relationship with NumPy and pandas data formats. The core idea of Seaborn is to integrate visualization as a critical part of data analysis and investigation; as a result, its plotting functions utilize data frames that cover the whole dataset.
Plotly is a widely used, open-source library designed for making interactive visualizations of data. It is based on the Plotly JavaScript library (plotly.js). It is capable of generating web-based visualizations that can be saved as HTML files or shown in Jupyter notebooks and web applications through Dash.
The various chart types include scatter, line, histogram, bar, box, pie, error Bars, Multiple axes, Sparklines, Dendrograms, 3-D, and more than 40 other displays. Plotly would suffice for Matplotlib and Seaborn to create appealing charts and graphical images for interactive dashboards. It is currently under the MIT license, which is favorable to its usage.
Machine learning and scikit-learn go hand in hand. Scikit-learn is one of the leading libraries for machine learning in Python. It is based on NumPy, SciPy, and Matplotlib and can be freely used and distributed under the BSD license, which means that it can be both open source and used for commercial purposes. When it comes to tasks that involve data prediction, this library provides a simple and efficient way of doing all that.
First published in 2007 and developed as one of the projects during the Google Summer of Code, Scikit-learn is an open-source tool. However, it also receives money from institutional and private sources to keep the business running.
