    Java:

        static SinglyLinkedListNode insertNodeAtTail(SinglyLinkedListNode head, int data) {
        if(head != null){
            if(head.next != null) {
                SinglyLinkedListNode node = head.next;
                while(node != null) { // Iterate trough list
                    if(node.next == null) {
                        node.next = new SinglyLinkedListNode(data);
                        break;
                    }
                    node = node.next;
                }
            } else {
                head.next = new SinglyLinkedListNode(data);
            }
        }else {
            head = new SinglyLinkedListNode(data);
        }
        return head;
    }

    Sorry: TabError: inconsistent use of tabs and spaces in indentation (Solution.py, line 53)

    Seriously this is a very poor site.

    I'm trying to run my code but it seems to be getting None as the object for the linkedlist. I'm pretty sure there is something wrong with the main function for the output file

    Python

    def insertNodeAtTail(head, data):
    node = SinglyLinkedListNode(data)
    if head is not None:
        current = head
        while current.next is not None:
            current = current.next
        current.next = node
    else:
        head = node
    
    return head
