text: user3719: well, I'm new to Bio. what I'm going to do is create a network/graph of a dataset related to the genes I think. here's the sample of the nodes dataset with CSV format named lung-nodes : 
  
  and this is a sample of edges I think with trrust name :
  
  these data are stored in two separate file
  what I must do is create a graph(network) of these nodes and edges by Python and a visualization library like networkX, but I do not how. 
  I must make a relation between these to the dataset by creating a graph of them
  can you help me out? 
  
  user3119: As far as I understand, it seems that the first table you provided contains biological/experimental information related to your genes, i.e. the nodes of the network you will build. The second table is the one you need to build the network: each line is an edge. You can use it as input and build the network using the IGraph library which works for both Python (as you requested) or R (as you suggested as an alternative).
  Most probably, but I can't say for sure, the first table was just a dataset from which you (or someone for you) recovered a list of nodes that where then submitted to a database, i.e. String, commonly used to recover information related to the interactions between your nodes, i.e. genes. Once you have this info (in the second table) you can build the network!
  edit:
  if you're not familiar with IGraph, you can have a look at this question describing how to obtain an IGraph graph from a csv file or this other one which uses a different csv file format to build a graph
