在magento产品2的页面上显示议会

Question

I'm trying to create just below the price an installment in the product page of Magento 2 both in the list and in the view of the product. In Magento 1 I used a helper for this $_corehelper for this however in Magento 2 Helper helpers are different I do not know how to implement it. Does anyone have a suggestion, as below is a snippet of code that I used to display the installment of the price.

<?php 
    $_coreHelper = $this->helper('core');
    $preco_produto = $_product->getFinalPrice();
    $percent = $_product->getResource()->getAttribute('percentual_parcela')->getFrontend()->getValue($_product);
    $discount_value = ($total / 100) * $percent;
    $final_price = $total - $discount_value;

    //Pega a quantidade de parcelas máxima configurada no produto
    $parceladesconto = $_product->getResource()->getAttribute('parceladesconto')->getFrontend()->getValue($_product);

    //% de desconto na parcela
    $percent = $_product->getResource()->getAttribute('percentual_parcela'); 
?>

<?php 
    $vezes = $_product->getData('parceladesconto');
    echo '<p id="title-parce"><small><b>Parcele em até<span id="title-vezes"> '.$vezes.'x </span> com Desconto</b></small><br />'; 
?>
