在python中打印图形的连接组件

在python中打印图形的连接组件,python,graph,networkx,Python,Graph,Networkx,我正在尝试打印图形的连接组件。但它的打印对象是生成器 这是我的graph.py import networkx as nx import matplotlib.pyplot as plt #import math import csv #import random as rand import sys def buildG(G, file_, delimiter_): #construct the weighted version of the contact graph from c

我正在尝试打印图形的连接组件。但它的打印对象是生成器

这是我的graph.py

import networkx as nx
import matplotlib.pyplot as plt
#import math
import csv
#import random as rand
import sys

def buildG(G, file_, delimiter_):
    #construct the weighted version of the contact graph from cgraph.dat file
    reader = csv.reader(open(file_), delimiter=delimiter_)
    for line in reader:
        if float(line[2]) != 0.0:
            G.add_edge(int(line[0]),int(line[1]),weight=float(line[2]))

def main():
    graph_fn="tempset3.txt";
    G = nx.Graph()  #let's create the graph first
    buildG(G, graph_fn, ',')

    print G.nodes()
    print G.number_of_nodes()

    #nx.draw(G)
    #plt.show(G)

    n = G.number_of_nodes()
    print ("no of nodes: ", n)
    comps=nx.connected_components(G)
    print comps

main()
这是我的tempset3.txt

0,1,9
1,3,5
1,4,17824
2,5,1199
2,6,729
5,7,619
5,8,241
5,10,227
7,8,4
当我运行它时,它会给出:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 10]
10
('no of nodes: ', 10)
<generator object connected_components at 0x360f140> 
[0,1,2,3,4,5,6,7,8,10]
10
(“节点数:”,10)
如何正确打印连接的组件


输出应该是:[[0,1,3,4],[2,5,6,7,8,10]只需使用
生成器上的
列表
对象
打印(列表(comps))

或在生成器对象上迭代:

for comp in comps:
        print (comp)
[0, 1, 3, 4]
[2, 5, 6, 7, 8, 10]
for comp in comps:
        print (comp)
[0, 1, 3, 4]
[2, 5, 6, 7, 8, 10]
