Filter in “All Post” only specific posts

You can create an Array of the ID’s of the posts that you need to delete.
Then run a loop on that array and call wp_delete_post($id);.
Documentation for wp_delete_post()

Example:

$id_array = [ 33, 34, 35, 26];

foreach ( $id_array as $id ) {
    wp_delete_post( $id );
}

Thanks you @shashwatmittal.
I am not a developer. There is a way that i can filter in “All Post”, only those 300 specific posts?
