# Practical Data Wrangling with Pandas

## ABSTRACT
Hacking Python? Need to import some Excel data and run a detailed data analysis? Got Pandas? Pandas has become a staple in the Python data science stack with strengths in data manipulation and analysis. In this workshop, we will focus on real-world data analysis scenarios that show the strengths of this library. We’ll cover basic Pandas data structures, core import/export and I/O functionality, manipulation of data in Pandas and the basics of Pandas data visualization. We will focus on the practical so that you can leave ready to apply your skills. We assume a basic working knowledge of Python and exposure to Jupyter Notebooks.

## ABOUT

This talk was originally given on August 17, 2017 at the Rocky Mountain Advanced Computing Consortium (RMACC) 2017 Symposium.

There are two parts to this repository:

1. **the slides** which can best be [viewed here](http://keithmaull.com/talks/20170817/slides), though the HTML source is [here](./slides); NOTE: _slides prepared using the [RISE plugin](https://github.com/damianavila/RISE) for Jupyter Notebooks and [NBExtensions](http://jupyter-contrib-nbextensions.readthedocs.io/en/latest/install.html)_

2. **the notebooks** which are supplemental to the slides (and also the basis for their content); they are [best viewed with NBViewer starting here](http://nbviewer.jupyter.org/urls/code.keithmaull.net/kmaull/talk_2017_08_RMACC_GotPandas/raw/master/nb/0_introduction.ipynb), but you are free to clone the repo and work on the notebooks from it or from NB
