检索部分密钥的部分密钥'... - Networkx

Question

我在尝试本教程："Networks on Maps (with Python)"。在原作者的善意帮助下，我已经掌握了大部分工作。它最初是在Python 2.7中创建的，我使用的是3.5。更改包括graphml格式的数据（不是pickle），插入缺少的参数，并指定G = nx.Graph（）。

我现在坚持朝着错误的结尾：

NameError: name 'part' is not defined. 

我有点不确定，如果它是一个2.7-3.5冲突，如果有一个功能缺失？

下面的代码：

import matplotlib.pyplot as plt 
import networkx as nx 
from mpl_toolkits.basemap import Basemap 
import difflib 

m = Basemap(projection='robin',lon_0=0,resolution='l') 

m.drawcountries(linewidth = 0.5) 
m.fillcontinents(color='white',lake_color='white') 
m.drawcoastlines(linewidth=0.5) 

# load geographic coordinate system for countries 
import csv 
country = [row[0].strip() for row in csv.reader(open('LonLat.csv'), delimiter=';')] # clear spaces 
lat = [float(row[1]) for row in csv.reader(open('LonLat.csv'), delimiter=';')] 
lon = [float(row[2]) for row in csv.reader(open('LonLat.csv'), delimiter=';')] 

G=nx.Graph() 

# define position in basemap 
    position = {} 
    for i in range(0, len(country)): 
     position[country[i]] = m(lon[i], lat[i]) 

    def similar(landstring, country): 
     l = difflib.get_close_matches(landstring, country, 1) 
     return l[0] 

    pos = dict((land, position[similar(land, country)]) for land in G.nodes()) 

    nx.draw_networkx_nodes(G, pos, nodelist = [**key for key in part if part[key] == 0**], 
     node_size = [deg_weight[s]*10 for s in part if part[s] == 0], 
     node_color = 'red', node_shape='^', alpha=0.8) 
     nx.draw_networkx_nodes(G, pos, nodelist = [key for key in part if part[key] == 1], 
     node_size = [deg_weight[s]*20 for s in part if part[s] == 1], 
     node_color = 'black', node_shape='d') 
     nx.draw_networkx_nodes(G, pos, nodelist = [key for key in part if part[key] == 2], 
     node_size = [deg_weight[s]*10 for s in part if part[s] == 2], 
     node_color = 'green', node_shape='o') 
     nx.draw_networkx_nodes(G, pos, nodelist = [key for key in part if part[key] == 3], 
     node_size = [deg_weight[s]*10 for s in part if part[s] == 3], 
     node_color = 'blue', alpha=0.8) 
     nx.draw_networkx_edges(G, pos, color='grey', width = 0.75, alpha=0.2) 
     plt.show() 

感觉就像这个答案（How to retrieve or iterate over edge keys in python networkx MultiDiGraph），这个答案（Python Tulpe Key For Dict Partial Lookup），而这个答案（How to access keys in nodes and edges in NetworkX MultiDiGraph）在正确的方向指向，但我不能让足够的链接。

任何输入将不胜感激。我很乐意让它充分发挥作用。

下面的代码几乎完全工作。一些小问题仍然存在，例如地图出现在边缘和节点的“上方”，“deg_weight”没有定义，但它大部分是有效的。如果我完全解决问题，我会发布。在这里发布任何有兴趣的人。感谢Raphael Heiberger博士的慷慨帮助。
