Wagtail tutorial

Thanks to [Serafeim Papastefanos] for authoring this tutorial. Please note that the installation process is in flux; most of the steps here should soon be unnecessary.

[Wagtail] is a new Open Source [Django]-based CMS. In this 20 minute tutorial we will see how you can create a blog from scratch using Wagtail. If you want to see some more examples of usage please take a look at the [wagtaildemo] GitHub project.

To follow this tutorial you will need to have [Python] 2.7 installed with a working version of [pip] and [virtualenv].

R to python useful data wrangling snippets

The dplyr package in R makes data wrangling significantly easier. 
The beauty of dplyr is that, by design, the options available are limited. 
Specifically, a set of key verbs form the core of the package. 
Using these verbs you can solve a wide range of data problems effectively in a shorter timeframe. 
Whilse transitioning to Python I have greatly missed the ease with which I can think through and solve problems using dplyr in R. 
The purpose of this document is to demonstrate how to execute the key dplyr verbs when manipulating data using Python (with the pandas package). 

dplyr is organised around six key verbs
