ipython 学习笔记 2 network graph--NetworkX

如果NetworkX不好用，pip uninstall 然后install

1) 看每个node的social情况

In [1]: import networkx as nx
In [2]: nx.read<点击TAB看选项> 比如
nx.read_adjlist nx.read_dot nx.read_edgelist

这个时候应该在有一系列edges和dot的文件夹 fbdata里
In [3]: g = nx.read_edgelist('0.edges')
此时g继承了read的各种method，查看g的情况
In [5]: len(g.nodes()), len(g.edges())
Out[5]: (333, 2519)

The 0 ego user then appears to have 333 friends（nodes）, and there are 2519 connections(edges) between these friends. 

2） 看social network的structure

sg = nx.connected_component_subgraphs(g)
[len(s) for s in sg]
这里因为sg是个generator object 书上的用法不对，但是我不知道怎么改
s1 =list(sg)
s1 = s1[0]
nx.radius(sg), nx.diameter(sg)

可能是版本问题，
