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]

我想绘制度分布网络图 我该如何更改字典来解决?

推荐答案

在Python3中，dict.values()返回视图"而不是列表:

In Python3 dict.values() returns "views" instead of lists:

• dict方法dict.keys()，dict.items()和dict.values()返回视图"而不是列表. https://docs.python.org/3/whatsnew/3.0.html

• dict methods dict.keys(), dict.items() and dict.values() return "views" instead of lists. https://docs.python.org/3/whatsnew/3.0.html

要将视图"转换为列表，只需将in_degrees.values()包裹在list()中:

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]
