how to make multiple counter buttons not interfere with each other

So basically I am making an online restaurant website where you can order food. I am going to make cards for each food item listed. Right now, I am making buttons that add and subtract the number of each item the customer wants to purchase.

var counter = document.querySelector(".count");
var currentNumber = 0;
var classicBurger = 5.18;
var bargeBurger = 6.13;

function addOne(price) {
  currentNumber += 1;
  counter.innerHTML = currentNumber;
  document.querySelector(".total-price").innerHTML =
    "$" + (price * currentNumber).toFixed(2);
}

function subtractOne(price) {
  if (currentNumber > 0) {
    currentNumber += -1;
    counter.innerHTML = currentNumber;
    document.querySelector(".total-price").innerHTML =
      "$" + (price * currentNumber).toFixed(2);
  } else {
    counter.innerHTML = 0;
  }
}
   <html>
     <div class="food-item">
        <h3 class="item-title">Classic Burger</h3>
        <p class="item-description">
          Classic beef patty with lettuce, tomato, and cheese.
        </p>

        <div class="add-subtract-items">
          <button class="subtract-item" onclick="subtractOne(classicBurger)">
            -
          </button>
          <span class="count">0</span>
          <button class="add-item" onclick="addOne(classicBurger)">+</button>
        </div>

        <p class="total-price">$0.00</p>
      </div>

      <div class="food-item">
        <h3 class="item-title">Barge Burger</h3>
        <p class="item-description">
          Classic beef patty with lettuce, tomato, and cheese.
        </p>

        <div class="add-subtract-items">
          <button class="subtract-item" onclick="subtractOne(bargeBurger)">
            -
          </button>
          <span class="count">0</span>
          <button class="add-item" onclick="addOne(bargeBurger)">+</button>
        </div>

        <p class="total-price">$0.00</p>
      </div>
      <html/>

How do I get the second button to effect the correct HTML rather than the total of the first item?

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() ...
