Best Data Science Packages for Python

Here in this article, we have provided the top 10 data science packages for Python that you can use for your data science projects and ML models. Data science, machine learning, and artificial intelligence are related to each other, so these packages can also be used for AI and Machine learning projects as well.

Python is all about its powerful libraries and packages. A library is a prewritten code that contains many modules that you can import into your program to enhance and add extra functionality. A package, on the other hand, could be defined as a distributed folder that contains many libraries and executable code. In simple words, we can say that a package is a collection of libraries.

In the last five to ten years, fields like data science, machine learning, artificial intelligence, and deep learning gained too much popularity all over the world, and Python is at the core of all these fields. This is because Python has many powerful packages and libraries for the development of these fields. So, let’s start discussing the best data science packages for Python.

10 Python Data Science Packages and Libraries

1. Pandas

pip Installation Command: pip install pandas

Pandas is an open-source data science package frequently used for data analysis and machine learning algorithms. It provides developers with fast, flexible, and expressive data structures. The main objective of this data science package in Python is to build a high-level block for practical and real-world data analysis using python.

It is one of the most important and flexible tools for data analysis and manipulation. Also, Pandas can work with different kinds of data sets, such as tabular data with heterogeneously-typed columns (SQL or Excel spreadsheets), arbitrary matrix data, ordered and unordered (not necessarily fixed-frequency) time-series data, and any other form of statistical data.

Pandas is built on the NumPy package, which is specially designed for mathematical and scientific computations. That’s why Pandas is also capable of handling mathematical tools for statistics. It uses two primary data structures that are Series (1-D) and Data Frames (2-D), and projects like finance, statistics, social science, and many areas of engineering often use these data structures.
