如何在py2neo中将字典对象转换为Node？

Question

I have a dictionary object like the following

node_info = {'id':'2344','name':'xyz'}

I want to convert it to py2neo Node so that it can be created using graph.create() . Node.cast() is no longer supported. Any other way

Answer 1

According to the definition for py2neo v4.0's Node class :

class py2neo.data.Node(*labels, **properties)

which means you can pass any number of labels:

Node("Person", "Professor")

and any number of labelled/named properties:

Node(id=10, name="Long John Silver")

---

Answering your question

You can achieve the above with either a list (for labels) and dict (for named properties):

labels = ["Person", "Professor"]
props  = {"id": 10, "name": "Long John Silver"}
print(Node(*labels, **props))

will yield:

(:Person:Professor {id: 10, name: 'Long John Silver'})

This is because of Python's *args and **kwargs in python Geeks4Geeks ref
