• Primarily built for polars data frames, showstats converts other inputs.

  • For full compatibility with pandas.DataFrames install via pip install showstats[pandas].

• Heavily inspired by the great R-packages skimr and modelsummary.

• Numbers with many digits are automatically converted to scientific notation.

• Because showstats leverages polars efficiency, it`s fast: <1 second for a 1,000,000 × 1,000 data frame, running on a M1 MacBook.
