framezip 0.1.0

Utilities to pack and unpack pandas DataFrames

framezip

A lightweight Python module for packing and unpacking pandas DataFrames by grouping rows into list-aggregated columns and exploding them back into individual rows.

---

Features

• Pack rows sharing common keys into a single row with list-aggregated columns.
• Unpack those list columns back into multiple rows.
• Flexible column referencing by name or integer index.

---

Installation

Make sure you have pandas installed:

pip install framezip

Use Cases

• Aggregate user sessions or grouped events into compact representations.
• Compress DataFrame rows for efficient storage or transfer.
• Switch easily between grouped (packed) and row-wise (unpacked) views.
• Prepare data for modeling or reporting workflows requiring different granularities.

Notes

• Accepts column indices or names for flexibility.
• Uses pandas groupby().agg(list) and explode() for performance.
• Requires pandas version 0.25 or later (for explode() support).
