How can I get a method to print?

code = int(input("Get the code: "))
name = "Anonymous"
number = 7
print("{0}'s length is {1}".format("{0}'s number is {1} and the code is {2}. The final length of the string is {3}".format(name,number,code,len(name+str(number)+str(code))), len("{0}'s number is {1} and the code is {2}. The final length of the string is {3}".format(name,number,code,len(name+str(number)+str(code)))))

public Node add(String element, Node bstree)
{ 
    if (root == null)
    {
        root = new Node(element);
        return root;
    }

    if (bstree == null)
    {
        return new Node(element);
    }
    else if (element.compareTo(bstree.value) < 0)
    {
        bstree.leftChild = add(element, bstree.leftChild);
    }
    else
    {
        bstree.rightChild = add(element, bstree.rightChild);
    }

    return bstree;
}

def l = [1, 2, 3, ]

groovy> def l = [1, 2, 3, ] 

Result: [1, 2, 3]
