#问题分析:. The code is as follows:
import networkx as ne #导入建网络模型包, named ne
import matplotlib.pyplot as MP #导入科学绘图包, named MP
#BA Scale-free Degree network graphy
ba=ne.barabasi_albert_graph (50,1)
ps=ne.spring_layout (BA) #布置框架
ne.draw (BA, ps,with_labels=false,node_size=30)
mp.show ()

Run Result:

Note: The Barabasi_albert_graph (n, m) method is used to generate a BA scale-free network containing n nodes and adding m bars at a time. This method generates 50 nodes in this program, each adding a 1-edge BA scale network graph.
