Prestashop 1.7 add extra info in cart-summary-subtotals.tpl

I try to add some extra info in the cart-summary-subtotals.tpl _partial template. Unfortunately, the controller is in the src folder and cannot be override.

What I try to do? I try to add a country next to the 'Shipping' label from the cart, similar to 'Shipping to Austria'. The country details are found in a dropdown from a module and can be pulled with Tools::GetValue('country') in a controller. So, I tried to assign a smarty variable in the CartController.php override function:

public function displayAjaxRefresh()
{
    if (Configuration::isCatalogMode()) {
        return;
    }

    ob_end_clean();
    header('Content-Type: application/json');
    
    $country = Tools::GetValue('country');
    $this->context->smarty->assign('country', $country);

    $this->ajaxRender(Tools::jsonEncode([
        'cart_detailed' => $this->render('checkout/_partials/cart-detailed'),
        'cart_detailed_totals' => $this->render('checkout/_partials/cart-detailed-totals'),
        'cart_summary_items_subtotal' => $this->render('checkout/_partials/cart-summary-items-subtotal'),
        'cart_summary_subtotals_container' => $this->render('checkout/_partials/cart-summary-subtotals'),
        'cart_summary_totals' => $this->render('checkout/_partials/cart-summary-totals'),
        'cart_detailed_actions' => $this->render('checkout/_partials/cart-detailed-actions'),
        'cart_voucher' => $this->render('checkout/_partials/cart-voucher'),
    ]));
}

and then changing the cart-summary-subtotals.tpl to capture the variable but it didn't work. Could someone guide me to how this one could be accomplished?

Thank you!

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() ...
