Highlight current page with included header file

I have a header file that I include with php on every page. Inside the navigation I use php to check if someone is logged in. Depending on the check the header looks different (different list items).

Following these guidelines (highlight the current page in menu in php) I am aware that a good way to achieve my goal is to declare a basename[PHP_SELF]-variable and then add some code to those list items.

But that is where I mess up. Since I already use php inside my html to check if the user is logged in or not I get lost in the single or double quotes I need to use to add the php code to my list items.

<header>
<nav class="nav collapsible">
<ul class="list nav__list collapsible__content">
    <?php
      echo "<li class='nav__item'><a href='contact.html'>Contact</a></li>";
      echo "<li class='nav__item'><a href='about.html'>About</a></li>";
  ?>

  </ul>
  <a class="nav__brand" href="index.html"><img class="link__logo" src="images/logoSmall.png" /></a>
  <svg class="icon icon--white nav__toggler">
    <use xlink:href="images/sprite.svg#menu"></use>
  </svg>
  <title class="header__title">My Page</title>
  <ul class="list nav__list collapsible__content">
    <?php
    if (isset($_SESSION["userid"])) {
      echo "<li class='nav__item'><a href='index.html'>Home</a></li>";
      echo "<li class='nav__item'><a href='shop.php'>Shop</a></li>";
      echo "<li class='nav__item'><a href='shoppingCart.html'>Shopping Cart</a></li>";
      echo "<li class='nav__item'><a href='includes/logout.inc.php'>Log Out</a></li>";
    }
    else {
      echo "<li class='nav__item'><a href='index.html'>Home</a></li>";
      echo "<li class='nav__item'><a href='signup.php'>Sign Up</a></li>";
      echo "<li class='nav__item'><a href='login.php'>Log In</a></li>";
    }
  ?>
  </ul>
</nav>

Could someone please help me out how my list items should look while being echoed? Thank you so much!

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() ...
