DS Python

Python

Python is a programming language widely used by Data Scientists.

Python has in-built mathematical libraries and functions, making it easier to calculate mathematical problems and to perform data analysis.

We will provide practical examples using Python.

To learn more about Python, please visit our Python Tutorial.

Python Libraries

Python has libraries with large collections of mathematical functions and analytical tools.

In this tutorial, we will use the following libraries:

Pandas - This library is used for structured data operations, like import CSV files, create dataframes, and data preparation
Numpy - This is a mathematical library. Has a powerful N-dimensional array object, linear algebra, Fourier transform, etc.
Matplotlib - This library is used for visualization of data.
SciPy - This library has linear algebra modules

We will use these libraries throughout the tutorial to create examples.
