​
N   Nodes

Select nodes from your graph to begin traversal. 
N<Type>(node_id)

​
Example 1: Selecting a user by ID

QUERY GetUser (user_id: ID) =>
    user <- N<User>(user_id)
    RETURN user

QUERY CreateUser (name: String, age: U8, email: String) =>
    user <- AddN<User>({
        name: name,
        age: age,
        email: email
    })
    RETURN user

from helix.client import Client

client = Client(local=True, port=6969)

user = client.query("CreateUser", {
    "name": "Alice",
    "age": 25,
    "email": "alice@example.com",
})
user_id = user[0]["user"]["id"]

result = client.query("GetUser", {"user_id": user_id})
print(result)

​
Example 2: Selecting all users

QUERY GetAllUsers () =>
    users <- N<User>
    RETURN users

from helix.client import Client

client = Client(local=True, port=6969)

result = client.query("GetAllUsers")
print(result)
You can also do specific property based filtering, e.g returning only ID, see the Property Filtering. You can also do aggregation steps, e.g returning the count of nodes, see the Aggregations.
