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. 
• Introduction to TensorFlow and Keras
