pandas-indexing 0.5.2

Description:

pandasindexing 0.5.2

Summary
pandas-indexing is a helpers package to make interacting with pandas multi-indices less
painful. It contains functions, that

filter easily into multi indices: isin, ismatch
add or update levels in a multiindex: assignlevel
select one or multiple specific levels: projectlevel



Usage
Given you have a time-series like dataframe with several multi index levels, like model, scenario, variable:
then you can select a subset with:
df.loc[isin(model="m1", scenario=["s1", "s2"])]
or with shell like glob-patterns:
df.loc[
ismatch(
model="REMIND*", variable="Emissions|**", unit=["Mt CO2/yr", "kt N2O/yr"]
)
]
You can overwrite index levels:
assignlevel(df, selected=1)
or project your data to only a few desired index levels:
projectlevel(df, ["model", "scenario"])
All commands are described in detail in the API reference in documentation and are
togehter with introductions for installing and using this package, but they are mostly
bare-bones atm.
