Object-Oriented Python
Sometimes simple scripts with functions in them just aren't enough. Eventually you'll need logical models of your work and that'll lead you to creating custom classes in Python. Object-oriented programming is a large topic. It provides us some amazing tools, though, so it's one of the most beneficial things to learn about in Python. First, you'll learn how to build basic custom classes. Then, you'll expand them through inheritance. And for some extra power, you'll also learn how to take control of Python's built-in classes to make your own more powerful while doing less work. Finally, we'll put everything together into a fun game utility.

Introduction to Data Visualization with Matplotlib
Get started creating charts with the Python library, matplotlib, an industry-standard data visualization library. Matplotlib provides a way to easily generate a wide variety of plots and charts in a few lines of Python code. It is an open-source project that can be integrated into Python scripts, jupyter notebooks, web application servers, and multiple GUI toolkits. Whether you are exploring sample data available on the internet, or your own business data, learning matplotlib is a great place to start your data visualization journey.

Machine Learning Basics
Machine learning encompasses many different ideas, programming languages, frameworks, and approaches to the subject, so the term "machine learning" is difficult to define in just a sentence or two. But essentially, machine learning is giving a computer the ability to write its own rules and learn about new things, on its own. In this course, we'll explore some of the big ideas, and toward the end, we'll even write a little bit of code in Python that can make some intelligent predictions.

Beginning Data Science
Data science unifies statistics, data analysis, machine learning and their related methods in order to understand and analyze actual phenomena with data. It employs techniques and theories drawn from many fields within the context of mathematics, statistics, information science, and computer science.
In this track, we'll be exploring the tools and techniques to get you started on your journey.
You'll pick up the basic building blocks of how to analyze and communicate data findings.
The first course you'll take is Data Analysis Basics, where you'll establish some language and definitions as well as how to think about data. Next, we'll cover some Python topics, as it's the language data scientists use the most. You'll establish a firm foundation in Python lists, dictionaries, sequences, tuples, and more.
Next we'll cover how to install and use Anaconda, as well as Jupyter Notebooks, two useful tools for your Python work. Additionally, you'll start creating charts with the Python library matplotlib, an industry standard data visualization library. Matplotlib provides a way to easily generate a wide variety of plots and charts in a few lines of Python code.
You'll get a basic introduction to NumPy, the fundamental package for scientific computing, and then pandas, which provides fast, flexible, and expressive data structures for your Python data work.
We'll then cover some best practices for cleaning and preparing data, data visualization, and an introduction to scraping data from the Web. To wrap up this Track, you'll take our Introduction to Big Data course and then our Machine Learning Basics course.
