NetworkX

import networkx as nx


一、创建空的图

1.G = nx.Graph() #创建无向图
2.G = nx.Digraph() #创建有向图

二、添加节点Nodeedgeweighted_edge

  • Graph.__init__(**attr[, data]) Initialize a graph with edges, name, graph attributes.

  • Graph.add_node(n, **attr[, attr_dict]) Add a single node n and update node attributes.

  • Graph.add_nodes_from(nodes, **attr) Add multiple nodes.

  • Graph.remove_node(n) Remove node n.

  • Graph.remove_nodes_from(nodes) Remove multiple nodes.

  • Graph.add_edge(u, v, **attr[, attr_dict]) Add an edge between u and v.

  • Graph.add_edges_from(ebunch,**attr[,attr_dict])Add all the edges in ebunch.

  • Graph.add_weighted_edges_from(ebunch,**attr)Add all the edges in ebunch as weighted edges with specified weights.

  • Graph.remove_edge(u, v) Remove the edge between u and v.

  • Graph.remove_edges_from(ebunch) Remove all edges specified in ebunch.

  • Graph.add_star(nodes, **attr) Add a star.

  • Graph.add_path(nodes, **attr) Add a path.

  • Graph.add_cycle(nodes, **attr) Add a cycle.

  • Graph.clear() Remove all nodes and edges from the graph.

三、迭代节点Nodeedge
