This class is a comprehensive introduction to data analysis with the Python programming language. This class targets people who have some basic knowledge of programming & want to take it to the next level. It introduces how to work with different data structures in Python & covers the most popular data analytics & visualization modules, including numpy, scipy, pandas, matplotlib, & seaborn. We use Ipython notebook to demonstrate the results of codes & change codes interactively throughout the class.
Some rudimentary knowledge of programming
Unit 1: Introduction to Python
Python is a high-level programming language. You will learn the basic syntax & data structures in Python. We demonstrate & run codes within Ipython notebook, which is a great tool providing a robust & productive environment for interactive & exploratory computing.
Introduction to Ipython notebook
Basic objects in Python
Variables & self-defining functions
Unit 2: Explore Deeper with Python
Python is an object-oriented programming (OOP) language. Having some basic knowledge of OOP will help you understand how Python codes work. More often than not, you will have to deal with data that is dirty & unstructured. You will learn many ways to clean your data such as applying regular expressions.
Introduction to object-oriented programming
How to deal with files
Run Python scripts
Handling & processing strings
Unit 3: Scientific Computation Tools
There are two modules for scientific computation that make Python powerful for data analysis: Numpy & Scipy. Numpy is the fundamental package for scientific computing in Python. SciPy is an expanding collection of packages addressing scientific computing.
Unit 4: Data Visualization
Python can also generate graphics easily using â€œMatplotlibâ€ & â€œSeabornâ€. Matplotlib is the most popular Python library for producing plots & other 2D data visualizations. Seaborn is a Python visualization library based on matplotlib. It provides a high-level interface for drawing statistical graphics.
Unit 5: Data manipulation with Pandas
Pandas provides rich data structures & functions for working with structured data. The â€œDataFrameâ€ object in Pandas is just like the â€œdata.frameâ€ object in R. Pandas makes data manipulation (filter, select, group, aggregate, etc.) as easy as in R.
After 20 hours of structured lectures, students are encouraged to work on an exploratory data analysis project based on their own interests. A project presentation demo will be arranged afterwards.
