An Introduction to Stock Market Data Analysis with Python (Part 1)

This post is the first in a two-part series on stock data analysis using Python, based on a lecture I gave on the subject for MATH 3900 (Data Science) at the University of Utah. In these posts, I will discuss basics such as obtaining the data from Yahoo!

This first post discusses topics up to introducing moving averages.
