Why networkx list(g.edges) does not return int?

pair = list(g.edges()) print(pair)

Why is the result of the second node is not an 'int'? result

I used firstnode = pair[a][0], secondnode = int(pair[a][1] for converting the number of the second node from a float to an int. But I am still confused why it is float?

Solution

So I am not entirely sure how your code looks like, but since you have for all of the edges in your graph a float as the second number and you want to type it as an integer, I would suggest you to do this:

My code example:

import networkx as nx

# Create dummy graph
g = nx.Graph()
g.add_edge(1,2.0)
g.add_edge(5,4.3)
g.add_edge(8,3.9)

# Get list of all edges
pair = list(g.edges())
print(pair)

# Iterate through all edges
for a in range(len(g.edges())):
  # Get first node of edge
  firstnode = pair[a][0]
  # Get second node of edge and type cast it to int
  secondnode = int(pair[a][1])
  # Print nodes / or execute something else here
  print(firstnode,secondnode)
  print()

And this is the output:

[(1, 2.0), (5, 4.3), (8, 3.9)]
1 2

5 4

8 3

I hope that helps!
