安装:
- 直接在命令行
pip3 install py2neo
- 官网下载(解压后放到python下的scripts中,在py2neo目录下cmd,输入python setup.py install
链接
auth=(用户名,密码)
from py2neo import Graph,Node,Relationship
graph = Graph("http://localhost:7474",auth=("neo4j","password"))
-
问题:unauthorized(self.uri.string)
-
解决方法:
from py2neo import authenticate,Graph authenticate("localhost:7474","账号","密码") graph = Graph("http://localhost:7474/db/data")
创建节点和关系
(已通过batch-import导入,这步省略
a = Node("Person", name="Alice")
b = Node("Person", name="Bob")
ab = Relationship(a, "KNOWS", b)
graph.create(ab)
查询
查询节点(使用原生查询语句
from py2neo import authenticate,Graph
graph = Graph("http://localhost:7474",auth=("neo4j","password"))
str = "match (变量名a:标签名{属性名:特定属性值}) return a"
x = graph.run(str).data()
y = pd.DataFrame(x)
