我一直在尝试向我正在创建的节点添加类似名称的属性,但收到错误消息。 error
# add name as a property to each node
# with networkX each node is a dictionary
G.add_node(tweeter_id,'name' = tweeter_name)
G.add_node(interact_id,'name' = interact_name)
这就是我得到的错误。 error message
File "<ipython-input-31-55b9aecd990d>", line 28
G.add_node(tweeter_id,'name' = tweeter_name)
^
SyntaxError: expression cannot contain assignment, perhaps you meant "=="?
以下是完整的代码供参考:
import networkx as nx
# define an empty Directed Graph
# A directed graph is a graph where edges have a direction
# in our case the edges goes from user that sent the tweet to
# the user with whom they interacted (retweeted, mentioned or quoted)
#g = nx.Graph()
G = nx.DiGraph()
# loop over all the tweets and add edges if the tweet include some interactions
for tweet in tweet_list:
# find all influencers in the tweet
tweeter, interactions = getAllInteractions(tweet)
tweeter_id, tweeter_name = tweeter
tweet_id = getTweetID(tweet)
# add an edge to the Graph for each influencer
for interaction in interactions:
interact_id, interact_name = interaction
# add edges between the two user ids
# this will create new nodes if the nodes are not already in the network
# we also add an attribute the to edge equal to the id of the tweet
G.add_edge(tweeter_id, interact_id, tweet_id=tweet_id)
# add name as a property to each node
# with networkX each node is a dictionary
G.add_node(tweeter_id, tweeter_name)
G.add_node(interact_id, interact_name)
这是因为
add_node
是一个函数。你不能给函数赋值当您尝试时,您正在这样做:
UPD:由于您使用的是networkx库,因此您可以查看他们关于添加节点函数here的文档
我相信你想做的是:
或者像提比一样。M指出,你也可以做:
而不是你的
使用
(假设您为变量
tweeter_name
和interact_name
分配了一些字符串)正如你从the documentation读到的
因此,使用关键字参数
name
来定义属性。(注意:不带引号,否则它将是一个
str
,并将导致您面对的SyntaxError
,因为它是对字符串文字的赋值)这样做:
它应该会起作用
