Question

我使用NetworkX来计算网络的某些中心度量标准。如何以表格格式将这些结果保存到csv文件中？我只能在终端打印结果。

G = nx.Graph()

G.add_edges_from([(1,2),(1,3),(2,3),(3,4),(4,5),(4,6)])


DEGREE_CENTRALITY = nx.degree_centrality(G)
EIGENVECTOR = nx.eigenvector_centrality(G)
KATZ = nx.katz_centrality_numpy(G)
CLOSENESS_CENTRALITY = nx.closeness_centrality(G)
BETWEENNESS_CENTRALITY = nx.betweenness_centrality(G)
CLUSTCOEF = nx.clustering(G)

在终端中打印结果：

      for n in G: print ("%s, %f, %f, %f, %f, %f, %f"%(n, DEGREE_CENTRALITY[n], 
    EIGENVECTOR[n], KATZ[n], CLOSENESS_CENTRALITY[n], BETWEENNESS_CENTRALITY[n], 
CLUSTCOEF[n]))

            ... 
            1, 0.400000, 0.456986, 0.408764, 0.500000, 0.000000, 1.000000
            2, 0.400000, 0.456986, 0.408764, 0.500000, 0.000000, 1.000000
            3, 0.600000, 0.584217, 0.448883, 0.714286, 0.600000, 0.333333
            4, 0.600000, 0.417117, 0.441314, 0.714286, 0.700000, 0.000000
            5, 0.200000, 0.183073, 0.367131, 0.454545, 0.000000, 0.000000
            6, 0.200000, 0.183073, 0.367131, 0.454545, 0.000000, 0.000000

您可以将其粘贴到pandas数据框中并使用to_csv方法。

import pandas as pd
import networkx as nx

G = nx.Graph()
G.add_edges_from([(1,2),(1,3),(2,3),(3,4),(4,5),(4,6)])

df = pd.DataFrame(dict(
    DEGREE_CENTRALITY      = nx.degree_centrality(G),
    EIGENVECTOR            = nx.eigenvector_centrality(G),
    KATZ                   = nx.katz_centrality_numpy(G),
    CLOSENESS_CENTRALITY   = nx.closeness_centrality(G),
    BETWEENNESS_CENTRALITY = nx.betweenness_centrality(G),
    CLUSTCOEF              = nx.clustering(G),
))

df.index += 1
df.to_csv('test.csv')
