Networkx / Data Science
#1
Hello,

i need your help with a project. I want to use Networkx to analyze relationships between data. For a first test I have the following database:

Document "node.csv" which includes the names for a Company, for example:
Company
A
B
C
...


And Document "edges.csv" which includes the Connections for a Company, for example:

Company, Employee
A, Max
B, John
C, Frank
...

With the following code I get the connection between the employees and the company:


with open('node.csv', 'r') as nodecsv:
    nodereader = csv.reader(nodecsv)
    nodes = [n for n in nodereader][1:]

node_names = [n[0] for n in nodes]

with open('edges.csv', 'r') as edgecsv:
    edgereader = csv.reader(edgecsv)
    edges = [tuple(e) for e in edgereader][1:]

G=nx.Graph()
G.add_nodes_from(node_names)
G.add_edges_from(edges)
print(nx.info(G))

nx.draw(G, with_labels = True, edge_color = 'g')
But my problem is that I have several employees at the company. If I now add more employees in Excel, I get the following error message in Python:

ValueError: dictionary update sequence element #0 has length 1; 2 is required


The Excel list should look like this:

Company, Employee
A, Max, Anna, Jennifer
B, John
C, Frank, Michael
...


Many thanks in advance!
Albert
