python-graph

A library for working with graphs in Python

This software provides a suitable data structure for representing graphs and a whole set of important algorithms.

INSTALLING

To install the core module, run:

pip install python-graph

To install the dot language support, run:

pip install python-graph[dot]

If you want the development version, use poetry. This will also install pytest and pydot.

pip install poetry
poetry install --with dev

And to run tests:

pytest

Coverage has some defaults set so simply run:

coverage run
coverage report
