pyshuf2

An inexact clone of GNU shuf. Free, implemented in Python.

Install

pyshuf2 can be installed via pip:

pip install pyshuf2

If you are installing the development version, just clone the repo & run this inside the cloned directory:

pip install -e .

This will also allow you to edit the program and then re-run it without reinstalling.
