pytae
Pandas extensions for everyday data-science tasks (filtering, selection, reshaping, aggregation, plotting), plus a pytae CLI that exposes the same operations for inspecting and converting tabular files (.parquet, .csv, .txt, .dat, .sas7bdat) without writing any Python.
Install
pip install pytae
CLI
pytae data.parquet -head
pytae data.parquet -qry "species: 'Adelie'" -select "species,body_mass_g" -convert -o subset.csv
pytae data.parquet -sql "select species, avg(body_mass_g) from df group by species"
pytae -file "data1.parquet=df1; data2.parquet=df2" -merge "left=df1,right=df2,on=id"
See docs/CLI.md for the full flag reference, and docs/CLI_MULTI_FILE.md for -file/-merge/-concat.
Plotting
Plotter: method-chainable plots on top of pandas.plot() (pip install pytae[plot]).
from pytae.plotting import Plotter
Plotter().data(penguins).plot(
x="bill_length_mm", y="bill_depth_mm", kind="scatter", c="species", cmap="viridis"
).finalize()
See docs/PLOTTING.md for more examples with sample data.
Library
Pandas extensions registered on pd.DataFrame — import pytae and the methods attach automatically.
- Filtering —
qry(): dict-based filters (equality, lists,in/not in, comparisons, intervals) - Selection —
select(): columns by name, regex, dtype, or name pattern - Reshaping —
long()/wide(): melt numeric columns to rows, pivot back to columns - Aggregation —
agg_df(): auto-detects group columns and aggregates the rest - Utilities —
to_clip(),handle_missing(),cols(),group_x(),clean_columns(),replace_values()
See docs/LIBRARY.md for examples of each.
