data set convert to matrix with tupel

I need to convert a part of my data to make it compatible with this solution: https://stackoverflow.com/a/64854873

The data is a pandas.core.frame.DataFrame with:

      result  data_1  data_2
1    1.523     4        1223
3    1.33     84        1534

Some index values might be removed, therefore 1, 3, ...

It should be a tuple with data values and the result. The type in the solution was scipy.sparse._coo.coo_matrix, like:

  (4, 1223) 1.523
  (84, 1534) 1.33

Just scipy.sparse.coo_matrix(df.values) seems to mix the data.

  (0, 0)    1.523
  (0, 1)    1.53
  (0, 24)   1.92
  : :
  (2, 151)  123.0
  (2, 142)  834.0

How can I generate a compatible matrix?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
