Machine Learning with Python Full Course 2023 | Python for Data Science |Python for Machine Learning
Hello and welcome to a Data science tutorial i.e. Python for machine learning, in 2023, presented by Great Learning. In this Python tutorial, you will be able to learn mathematical calculation, data frame manipulation & visualization with the aid of very important packages in python and the data science community i.e. NumPy, Pandas, & how to use Matplotlib and Seaborn.

What is NumPy?
NumPy is a tool for mathematical computing and data preparation in Python. It can be utilized to perform a number of mathematical operations on arrays, such as trigonometric, statistical, and algebraic routines. This library provides many useful features, including handling n-dimensional arrays, broadcasting, performing operations, data generation, etc. Thus, it’s the fundamental package for scientific computing with Python. It also provides a large collection of high-level mathematical functions to operate on arrays.
NumPy Arrays:
NumPy arrays will be the main focus of this course. So, what are arrays? Arrays are a reserved space in memory for a list of values. These arrays essentially come in two flavors: vectors and matrices. Vectors are strictly one-dimensional, and matrices are two or more dimensional arrays. They certainly take part in the root architecture of programming and give a whole lot of new possibilities, which will be explored later on.
What are Pandas?
In short, Pandas is a Software Library in Computer Programming, and it is written for the Python Programming Language. It works to do data analysis and manipulation.
How to use Matplotlib
Before using Matplotlib, we need to import the package. This can be done using the ‘import’ method in Jupyter notebook. PyPlot is the graphical module in Matplotlib, which is mostly used for data visualization. Importing PyPlot is sufficient to work around data visualization.
Seaborn:
Seaborn is an amazing data visualization library for statistical graphics plotting in Python. It provides beautiful default styles and color palettes to make statistical plots more attractive. It is built on top of the Matplotlib library and is closely integrated with pandas' data structures. In this tutorial, we shall see how to use seaborn to make a variety of plots and how we can use it along with Matplotlib to make our plots more attractive.
