"data": [
        {
            "id": 4200,
            "name": "Anti gravity Beer Cake",
            "modal": "",
            "price": 1800,
            "discount": 0,
            "quantity": 20,
            "discription": "Good Quality Product!",
            "p_status": "active",
            "m_id": 664,
            "product_link": "anti-gravity-beer-cake--6040c2b317894",
            "product_picture": " ",
            "weight": 0,
            "weight_type": "Kilogram",
            "rating": {
                "id": 4,
                "u_id": 1,
                "product_id": 4200,
                "subject": null,
                "ratings": 4,
                "review": null,
                "type": "rating"
            }
        },
{
            "id": 4200,
            "name": "Anti gravity Beer Cake",
            "modal": "",
            "price": 1800,
            "discount": 0,
            "quantity": 20,
            "discription": "Good Quality Product!",
            "p_status": "active",
            "m_id": 664,
            "product_link": "anti-gravity-beer-cake--6040c2b317894",
            "product_picture": " ",
            "weight": 0,
            "weight_type": "Kilogram",
            "rating": {
                "id": 5,
                "u_id": 1,
                "product_id": 4200,
                "subject": null,
                "ratings": 5,
                "review": null,
                "type": "rating"
            }
        }

But i want product having high rating first. How i an do it? product model:-

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class product extends Model
{
    use HasFactory;
    
    public function rating(){
        return $this->hasOne(ratings_and_review::class)->orderBy('ratings','DESC');
    }
}

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
