here is my code and the text file is here
import networkx as nx
import pylab as plt
webg = nx.read_edgelist('web-graph.txt',create_using=nx.DiGraph(),nodetype=int)
in_degrees = webg.in_degree()
in_values = sorted(set(in_degrees.values()))
in_hist = [in_degrees.values().count(x)for x in in_values]
I want to plot degree distribution web graph how can i change dict to solve?
In Python3 dict.values() returns "views" instead of lists:
- dict methods dict.keys(), dict.items() and dict.values() return "views" instead of lists. https://docs.python.org/3/whatsnew/3.0.html
To convert the "view" into a list, simply wrap in_degrees.values() in a list():
in_hist = [list(in_degrees.values()).count(x) for x in in_values]
just use list(in_degrees.values()).count(x)
worked for me!
If you want to count dictionary values you can do it like this:
len(list(dict.values()))
same method works for keys
len(list(dict.keys()))
Also keep in mind if you want to get all keys or values in list just use list(dict.values())
len(mydict) is sufficient, since in this context the len of a dict is the number of keys. No need to produce a list of the values or keys. And making a copy by the use of the list operator is unnecessary as well since both mydict.keys() and mydict.values() return lists.
dictmethods behave differently in Python 3 vs Python 2.
