Python Graph Library
PythonGraphPython Problem Overview
I'm writing a python application that will make heavy use of a graph data structure. Nothing horribly complex, but I'm thinking some sort of graph/graph-algorithms library would help me out. I've googled around, but I don't find anything that particularly leaps out at me.
Anyone have any good recommendations?
Python Solutions
Solution 1 - Python
There are two excellent choices:
and
I like NetworkX, but I read good things about igraph as well. I routinely use NetworkX with graphs with 1 million nodes with no problem (it's about double the overhead of a dict of size V + E)
If you want a feature comparison, see this from the Networkx-discuss list
Solution 2 - Python
I would like to plug my own graph python library: graph-tool.
It is very fast, since it is implemented in C++ with the Boost Graph Library, and it contains lots of algorithms and extensive documentation.
Solution 3 - Python
Have you looked at python-graph? I haven't used it myself, but the project page looks promising.
Solution 4 - Python
Also, you might want to take a look at NetworkX
Solution 5 - Python
Take a look at this page on implementing graphs in python.
You could also take a look at pygraphlib on sourceforge.
Solution 6 - Python
Solution 7 - Python
I'm having the most luck with pydot. Some of the others are hard to install and configure on different platforms like Win 7.
Solution 8 - Python
I second zweiterlinde's suggestion to use python-graph. I've used it as the basis of a graph-based research project that I'm working on. The library is well written, stable, and has a good interface. The authors are also quick to respond to inquiries and reports.
