i have to sort a list by value and pick the relative key [closed]

I have a dictionary with a name and a value. I want a way to sort for value and pick the name. Remind that the value will change, and this function will be called many times in the program

for example my dictionary is {"username" : score} i'm searching a way to pick the username of the top 4 user with the highest score

thank you so much

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

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() ...
