Description

This course will cover a crash course for scientific Python for data analysis for 15h. 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. Principal components analysis, clustering and supervised analysis with multivariate data.

Course goals

Learn python from scratch.
Learn the use of numpy and machine learning scientific kits in python.
