Extension framework for pandas
Project description
pandex - An Extension Framework for pandas
pandex
is a framework for creating, managing and sharing extensions
for the pandas
package.
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
with:
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
a column radius
, the extension can be called:
df.ext.circle_calculations()
To see the currently installed extensions:
pd.ext.show_extensions()
