Course 592:
Data Science with Python

(4 days)

 

Course Description

As we generate more and more data, business needs to make use of it for competitive advantage. What is needed is a consistent, easy to use set of tools, which an analyst can use interactively to extract business value in a timely manner.

Python is quick to learn and supplies tools for manipulating and analyzing data: pandas, numpy, scipy, scikit-learn. This course introduces attendees to these tools and via hands-on exercises based on real-world scenarios, shows how they can be applied to a range of business scenarios.

Learning Objectives

  • Learn to apply Python tools and Data Science libraries to provide business value
  • Learn basic and advanced NumPy (Numerical Python) features
  • Get started with data analysis tools in the pandas library
  • Use high-performance tools to load, clean, transform, merge, and reshape data
  • Create scatter plots and static or interactive visualizations with matplotlib
  • Apply the pandas groupby facility to slice, dice, and summarize datasets
  • UseScikit-learn for machine learning

Who Should Attend

Anybody involved in the processing and analysis of data using Python, including business analysts, data engineers, data scientists and software engineers.

Prerequisites

A basic knowledge of Python is required.
