mspu

MSPU: Minimal Set of Python Utilities

Lightweight utilities for pandas and Polars.

The mspu package provides a collection of commonly used utilities for DataFrame testing, manipulation, and inspection.

It currently includes:

• ht — Display the head and tail of pandas and Polars DataFrames.
• gen_rand_df — Generate dummy pandas DataFrames for testing.
• explode_date_range — Efficiently expand date ranges in pandas DataFrames into rows.

Installation

Using pip:

pip install mspu

Using uv:

uv pip install mspu

Quick Start

Display the head and tail of a DataFrame simultaneously with some display settings.

Import mspu.pandas to register the ht accessor on pandas DataFrames.

import pandas as pd
import mspu.pandas

df = pd.DataFrame({
  'foo': [1.12345, 2.98765, 3.14159],
  'bar': [7, 8, 9],
  'ham': ['x', 'y', 'z'],
})
# n: 1 - one row from the head and one row from the tail are displayed
# c: 2 - two columns are displayed
# r: 3 - the number of decimal places for number rounding
# w: -1 - unlimited display width
df.ht(n=1, c=2, r=3, w=-1)

The DataFrame will be displayed as:

shape: (3, 3)
     foo  ...  ham
0  1.123  ...    x
2  3.142  ...    z
