pytae
Pandas helpers 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 data group by species"
pytae -file "data1.parquet=df1; data2.parquet=df2" -merge "left=df1,right=df2,on=id"
See docs/FLAGS.md for which flag to use, docs/CLI.md for the full 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
Import pytae as pt. Same verbs work as pt.select(df, ...) or as df.pt.select(...) (mix with pandas: df.rename(...).pt.agg_df(...)). Notebooks use the accessor chain. CLI flags (-select, -qry, …) are unchanged.
import pytae as pt
penguins = pt.sample("penguins")
pt.select(penguins, "species", contains="bill")
(penguins
.pt.select("species", "island", "bill_length_mm", "body_mass_g")
.pt.agg_df(a=["mean", "n"])
)
- Filtering —
pt.qry(): keyword filters (equality, lists,in/not in, comparisons, intervals) - Selection —
pt.select(): columns by name, regex, dtype, or name pattern - Mutating —
pt.mutate(): create/overwrite columns via formulas,if_else(),case_when(),map() - Reshaping —
pt.long()/pt.wide(): melt numeric columns to rows, pivot back to columns - Aggregation —
pt.agg_df(): auto-detects group columns and aggregates the rest - Utilities —
pt.to_clip(),pt.handle_missing(),pt.cols(),pt.group_x(),pt.clean_columns(),pt.replace_values() - SQL —
pt.sql()/df.pt.sql()via duckdb (pip install pytae[sql]); the frame is tabledata
See docs/LIBRARY.md for examples of each.
