Dictionary of Series - a kind of pandas extension

DictOfSeries

DictOfSeries is a pandas.Series of pandas.Series objects which aims to behave as similar as possible to pandas.DataFrame.

Nomenclature

• series/ser: instance of pandas.Series
• dios: instance of dios.DictOfSeries
• df: instance of pandas.DataFrame
• dios-like: a dios or a df
• alignable object: a dios, df or a series

Features

• every column has its own index
• uses much less memory than a misaligned pandas.DataFrame
• behaves quite like a pandas.DataFrame
• additional align locator (.aloc[])

Install

todo: PyPi

import dios

# Have fun :)
