Programming with Data: Python and Pandas

This repository contains the slides, exercises, and answers for Programming with Data: Python and Pandas. The goal of this tutorial is to teach you, someone with experience programming in Python, most of the features available in Pandas. The material from this course has been presented at conferences including ODSC and Battlefin Discovery Data and online through the O'Reilly platform.

Why this course exists

Whether in R, MATLAB, Stata, or python, modern data analysis, for many researchers, requires some kind of programming. The preponderance of tools and specialized languages for data analysis suggests that general purpose programming languages like C and Java do not readily address the needs of data scientists; something more is needed.

In this workshop, you will learn how to accelerate your data analyses using the Python language and Pandas, a library specifically designed for interactive data analysis. Pandas is a massive library, so we will focus on its core functionality, specifically, loading, filtering, grouping, and transforming data. Having completed this workshop, you will understand the fundamentals of Pandas, be aware of common pitfalls, and be ready to perform your own analyses.

Prerequisites:

Workshop assumes that participants have intermediate-level programming ability in Python. Participants should know the difference between a dict, list, and tuple. Familiarity with control-flow (if/else/for/while) and error handling (try/catch) are required.

No statistics background is required.

Installation

Binder

If you have a stable Internet connection and the free Binder service isn't under too much load, the easiest way to interactively run the slides and try the exercises is to click the Binder badge (make sure you open in a new window). Keep in mind that Binder aggresively shuts down idle instances so you'll need to refresh the link if you're idle for too long.

Prerendered Notebooks

You may view the HTML versions of slides and the answers directly in your browser on Github though you will not be able to run them interactively:

Local Installation

If you're taking the course, want to follow along with the slides and do the exercises, and may not have Internet access, download and install the Anaconda Python 3 distribution and conda package manager ahead of time:

https://www.anaconda.com/download/

Download the latest version of the course materials here.

Alternatively, you may clone the course repository using git:

$ git clone https://github.com/dgerlanc/programming-with-data.git

The remainder of the installation requires that you use the command line.

To complete the course exercises, you must use conda to install the dependencies specified in the environment.yml file in the repository:

$ conda env create -f environment.yml

This will create an conda environment called progwd which may be "activated" with the following commands:

Windows: activate progwd
Linux and Mac: conda activate progwd

Once you've activated the environment your prompt will probably look something like this:

(progwd) $

The entire course is designed to use jupyter notebooks. Start the notebook server to get started:

(progwd) $ jupyter lab
