What you'll learn in this python class:

Python for Data Scientist and Machine Learning Practitioners

This is a 5 - day course that provides a ramp - up to using Python for data science/machine learning. Starting with the basics, it progresses to the most important Python modules for working with data, from arrays, to statistics, to plotting results. The material is geared towards data scientists and engineers. This is an intense, hands - on, programming class. All concepts are reinforced by informal practice during the lecture followed by lab exercises. Many labs build on earlier labs which helps students retain the earlier material. 

Python for Programming, Scikit-Learn and Tensorflow is a practical introduction to a working programming language, not an academic overview of syntax and grammar. Students will immediately be able to use Python to complete tasks in the real world.

Prerequisites

Students must have at least 1 year of hands on data science experience and must be comfortable working with a variety of machine learning algorithms. Students should also be comfortable working with files and folders, and should not be afraid of the command line in Linux, Windows, or MacOS.
