WordPress Function to Exclude child categories of a specific category

Exclude child categories of a specific category.

Pretty straight forward, but I couldn’t find anyone doing exactly what I needed. Also it will display the post if the parent category is selected, except if that post has a child category of that parent selected.

   /* this code excludes all of the children of (category id = 20) posts
       on the HOME page, but allows parent (category id = 20) to be shown. */

    function exclude_category_children($query) {
        $child_cats = (array) get_term_children('20', 'category');
        if ( $query->is_home ) {
        $query->set('category__not_in', $child_cats);
        return $query;
        }
    }
    add_filter('pre_get_posts', 'exclude_category_children');
