A Data Project Manager for IPython

Provides utilities and functions for managing data projects in python. Requires use of IPython and Pandas.

A quick workflow example:

from gloo import Gloo

proj = Gloo('My Project', full_structure, packages=['scipy',
                                          ('numpy', 'np')])

proj.create_project()

Introduction

Gloo's goal is to tie together a lot of the data analysis actions that happen regularly and make that processes easy. Automatically loading data into the ipython environment, running scripts, making utitlity functions available and more. These are things that have to be done often, but aren't the fun part.

proj.create_project() Options

project_name: This is a string that is the name of your project.

Current Config Options:

full_structure If True the folder structure outline below. By default creates smaller project, i.e. False.

packages A list of strings of python packages to load when load_project() is called. Defaults to empty. If you want to alias your package you can pass a tuple to the list. ['scipy', ('numpy', 'np')] will import scipy as scipy and numpy as np.

logging A boolean to dictate if logging is started when load_project() is called. Defaults to False.

svn Pass a list or a string to init version control. Currently supports git and bzr. svn = ['git', 'bzr'] will init both.

Those options are saved into a pickled file called .gloo at the root of the project directory.

What Happens When You Call load_project()

proj.load_project()

1. The config is loaded into a dictionary.
2. Data is the data directory is loaded into the environment. This is done recursively so you can have subdirectories. If you do, the parent folder of the data file will be prepended to data file, folder_file. The plan is to make the prepending optional.
3. Files in the munge directory are run. This folder is where you would put files necessary for preprocessing the data.
4. Files in the lib directory are imported. This folder is where you would put files that you would like to load as a module. So if you have utility.py in the lib directory. When you load the project you'll have utility availble in the namespace.
5. Packages specified in the config are loaded into the environment.
6. Logging starts

Folder Structure

The full structure is as follows:

data/        : data
doc/         : documentation
diagnostics/ : automatically check for data issues
graphs/      : graph domicile
lib/         : utility functions
munge/       : preprocessing scripts
profiling/   : benchmark performance
reports/     : reports you'll produce
tests/       : tests

Other things you can do

You can update the config. Say you have packages = ['numpy'] but once you've worked on the project you realize you need pandas and you want to load it as pd. It's easy to update this of the future:

>   proj.packages
    ['numpy']
>   proj.packages.append(('pandas', 'pd'))
>   proj.save_project()

So next time you load the project pandas as pd will be available.

Installing Gloo

• pip install Gloo is available.
• There is also an ubuntu package available on LaunchPad
• Gloo currently isn't supported on Windows

Contributing

Because this project is in such an early state I would love for anybody and everybody to help contribute. I think this could be very valuable for those working with python for data projets.

Thanks

This project is a bit of a rip-off or port (however nice you're feeling) of Project Template, which if you're using R I would highly recommend. It's fantastic.
