python match : confusion about match testing

I know there are other ways to do this, but I am want to use match here.

In this snip, the break piece matches for all integers > 0, but I want it to match only n' I'm using the cast because it wasn't working without it. Not working with it either but...

#times is a simple list of python datetimes

n=len(times)
for i,time in enumerate(times) :
    print(f'{i} {time}')
    match int(i):
        case 0 : 
            print('continuing') 
            continue
        case int(n) : 
            print(f'breaking for {i}')
            #break
        case __ :     
            period = times[i+1] - time
            print(period)

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() ...
