I’m trying to loop inside my post’s tag but this code return this string “1 · 1 · 1 · 1 · 1 · 1”

How can i loop inside post’s tag and show the icons??? thanks in advance

<?php $postid = get_the_ID();

$terms = get_the_terms( $postid, 'post_tag' );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ) {
    $count = count( $terms );
    $i = 0;
    $term_list = '';
    foreach ( $terms as $term ) {
        $i++;
	$icon = get_the_icon(array('size=medium&class=icone'), 'post_tag' , true);
    	$term_list .= print ( $icon );
    	if ( $count != $i ) {
            $term_list .= ' &middot; ';
        }
        else {
