Pandas cookbook

Binder

pandas is a Python library for doing data analysis. It's really fast and lets you do exploratory work incredibly quickly.

The goal of this cookbook is to give you some concrete examples for getting started with pandas. The docs are really comprehensive. However, I've often had people tell me that they have some trouble getting started, so these are examples with real-world data, and all the bugs and weirdness that entails.

It uses 3 datasets:

  • 311 calls in New York
  • How many people were on Montréal's bike paths in 2012
  • Montreal's weather for 2012, hourly

It comes with batteries (data) included, so you can try out all the examples right away.

How to use this cookbook

The easiest way is to try it out instantly online using Binder's awesome service. Start by clicking here, wait for it to launch, then click on "cookbook", and you'll be off to the races! It will let you run all the code interactively without having to install anything on your computer.

To install it locally , you'll need an up-to-date version of IPython Notebook (>= 3.0) and n your computer pandas (>=0.13) for this to work properly. It's set up to work with Python 2.7.

You can get these using

pip
(you may want to do this inside a virtual environment to avoid conflicting with your other libraries).
  pip install -r requirements.txt

This can be difficult to get set up and require you to compile a whole bunch of things. I instead use and recommend Anaconda, which is a Python distribution which will give you everything you need. It's free and open source.

Once you have pandas and IPython, you can get going!

git clone https://github.com/jvns/pandas-cookbook.git
cd pandas-cookbook/cookbook
ipython notebook

A tab should open up in your browser at

http://localhost:8888

Happy pandas!

run the container:
docker run -d -p 8888:8888 -e "PASSWORD=MakeAPassword" 
you can find out about the id of the image, by checking
docker images

After starting the container, you can access ipython notebook with the cookbook on port 8888. Remember to use https and authenticate with
