simple-graph 0.2.4

A simple graph package

Introduction

The simple-graph module contains basic functions for graph.

Concept

A graph is a structure to hold a set of objects in which some pairs of the objects are connected.

A graph contains two components: vertices and edges.

We consider both directed and undirected edges in this project. If the edges are undirected, the graph is called undirected graph, on the other hand, it is called directed graph.

Install

pip install simple-graph

or update

pip install --upgrade simple-graph

Usage

Basic operations

from simple_graph import Graph
G = Graph()
G.add_edge(1, 2)
print(G.has_edge(1, 2))

ouput:

True

G = Graph({0: [1, 2], 1: [2]})
print(G.neighbors(0))

output:

[1, 2]

Statistics

G = Graph({ 
    "a" : ["c"],
    "b" : ["c","e","f"],
    "c" : ["a","b","d","e"],
    "d" : ["c"],
    "e" : ["b","c","f"],
    "f" : ["b","e"]
})

print(G.find_path('a', 'b'))
print(G.diameter())

output:

['a', 'c', 'b']
