Topological Overlap

2014-08-16 Thread lavanya addepalli
Hello

I have a file with network node pairs and weights as time difference
I am trying to find the topological overlap of that data

I have been searching for any sample in python but i dont seem to find any.

Any suggestion in start with are appreciated


Thanks

Hello

It is not a homework really.
Actually it is a huge project and topological overlap is one part in that

inputfile:

0_node_1  0_node_2 w0
1_node_1  1_node_2 w1
2_node_1  2_node_2 w2
3_node_1  3_node_2 w3
4_node_1  4_node_2 w4
5_node_1  5_node_2 w5

2 nodes in pair and w is the weight. I have to find the topological overlap
in the network including the weights

 Homework?

 You need to give us a start, sample of the data and an actual question. I
 don't think many people will help you do your homework for you.

Hello Everyone

I am very much new to python scripting and i am here for knowledge
exchange.

I am trying to read a file with node pairs and weight.
I have to find the neighbours of each pair individual and combined
both also count them.
Later find the ratio of the neighbours that each node has. I am stuck
with finding nodes.

infile.txt

0_node1 0_node2 0w
1_node1 1_node2 1w
2_node1 2_node2 2w
3_node1 3_node2 3w
4_node1 4_node2 4w


import networkx as nx
import matplotlib.pyplot as plt

G=nx.Graph()
G = nx.read_edgelist('infile.txt', data=[(weight, float)])

def get_triangle(G):
  for n1 in G.nodes:
neighbors1 = set(G[n1])
for n2 in filter(lambda x: xn1, nodes):
neighbors2 = set(G[n2])
common = neighbors1  neighbors2
for n3 in filter(lambda x: xn2, common):
  print n1
  print n2
  print n3

Any suggestion will be appreciated. Thanks

Appending to a file using Python API

2010-07-08 Thread lavanya
Hello all,

How do you append to a file using Python os::file APIs. So that it
appends to the content of the file. Not adding the content to the new
line. But just appends next to the exiting content of the file.

Example : current content of file
A B C
if we append D to it, it should be
A B C D

Not like:
A B C
D

regards,
lavanya
