python-graph is 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.
The code is appropriately documented and API reference is generated automatically by epydoc.
Comments, bug reports and suggestions are welcome.
Current release: 1.6.2 - Sep 30, 2009
The 1.6.x series is our refactoring series. Along the next releases, we'll change the API so we can better prepare the codebase to new features. If you want a softer, directed transition, upgrade your code to every release in the 1.6.x series. On the other hand, if you'd rather fix everything at once, you can wait for 1.7.0.
Please check our Changelog for detailed information.
Installing
If you have easy_install on your system, you can simply run:
| # easy_install python-graph-core |
And, optionally, for Dot-Language support (requires pydot):
| # easy_install python-graph-dot |
Otherwise, you can download a package from the Downloads page.
Provided features and algorithms:
- Support for directed, undirected, weighted and non-weighted graphs
- Support for hypergraphs
- Canonical operations
- XML import and export
- DOT-Language output (for usage with Graphviz)
- Random graph generation
- Accessibility (transitive closure)
- Breadth-first search
- Critical path algorithm
- Cut-vertex and cut-edge identification
- Cycle detection
- Depth-first search
- Heuristic search (A* algorithm)
- Identification of connected components
- Minimum spanning tree (Prim's algorithm)
- Mutual-accessibility (strongly connected components)
- Shortest path search (Dijkstra's algorithm)
- Topological sorting
- Transitive edge identification
