Description

This course will cover a crash course for scientific Python for data analysis. This crash course will include three main stages:

    • Introduction to Python language as a tool. Workflow, ipython, ipython notebook (jupyter), basic types, mutability and inmutability and object oriented programming.
    • Short introduction to numerical Python and matplotlib for graphical visualization.
    • Introduction to scientific kits for data analysis with machine learning. Pandas. Principal components analysis, clustering and supervised analysis with multivariate data.

Course goals

    • To gain prosficiency in coding python, understand basic types
    • To learn how to build generators and cogenerators
