Extension framework for pandas
pandex - An Extension Framework for pandas
pandex is a framework for creating, managing and sharing extensions
There is a built-in extension system in
pandas but it is not
straightforward to share these between projects, virtual environments,
other users on the same server or indeed, the wider world.
pandex allows extensions to be installed from local files, directories
or directly from public GitHub repositories. Once installed, they persist
for a user across multiple virtual environments.
Any existing script can be upgraded to support extensions with a single line change. Simply replace:
import pandas as pd
import pandex as pd
and all dataframes created from
pd will be able to access installed extensions.
An demo extension which calculates the circumference and area of circles from a column of radius values can be installed:
pd.ext.import_extension('github:connectedblue/pdext_collection -> circle_calculations')
Whenever these calculations are required for a dataframe
df which contains
radius, the extension can be called:
