There are so many **Python** libraries for data science out there today that you will get the simplest alternative of almost any library. As a data scientist, you need to keep improving your skills, so you need to keep learning new libraries if they are better than the ones you are already using. But there are some very important Python libraries for data science that will help you learn the basics of working with data for a specific problem. Such libraries will not only help to solve any kind of data science problem but also help to learn and understand new libraries. So, if you want to know about all the important Python libraries for data science, this article is for you. In this article, I’m going to introduce you to all the important Python libraries for data science that every data scientist should know.

## Important Python Libraries for Data Science

#### NumPy

NumPy is the fundamental Python library for scientific computing. It offers comprehensive mathematical functions, random number generation, linear algebra functions, Fourier transforms, and many other numerical calculation tools. Some of the benefits of using NumPy for data science are:

- It provides powerful N-Dimensional arrays
- It provides a large variety of numerical computing tools
- It is interoperable
- Easy to use and learn

#### Matplotlib

Another very important Python library for data science is Matplotlib. It is a data visualization library for creating static, animated, and interactive visualizations using Python. Some of the features provided by matplotlib are:

- used to generate publication-quality visualizations
- can create interactive figures
- customizable visual styles and layouts
- can export visualizations to many file formats
