Python for Data Science Primer

New – Learn core Python data science skills.

GK# 100668

Course Overview

TOP

This course introduces data analysts, business analysts, and anyone interested in Data Science to the Python programming language as it’s often used in Data Science in web notebooks. The goal is to provide you with a baseline understanding of core concepts that will serve as a platform of knowledge to follow-up with more in-depth training and real-world practice.

The course begins with a quick overview of Python with demonstrations of both script-based and web notebook-based Python and then you’ll dive into the essentials of Python necessary for a data scientist. The end of the course explores a quick integration of these skills with key Data Science libraries including NumPy, Pandas, and Matplotlib.

This class is hands-on and includes light programming labs that introduce students to basic Python syntax and concepts applicable to using Python to work with data.
