Raymond Yee

January 30, 2014 (http://is.gd/wwod1404)

Goals Today

how to use the Python for Data Analysis, textbook for the course
getting oriented to the basics of numpy, pandas, and matplotlib

majot topics in PfDA

pandas with numpy implicitly
IPython notebook
matplotlib
nice example data sets which we will use (e.g., baby names)

Work through code in PfDA

A notebook I will talk about: Day_04_A_PfDA.ipynb

I will highlight important concepts
frankly, it took me a lot of trial and error in working through pandas, which has a large and complicated structure
