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
To learn how to build and manage data-frame-based representations of data
To learn how to use machine learning scientific kit (sklearn)
