### Tell us what’s happening:

I’m not sure what I’m missing here.

Inside the search method, delete pass and call the helper method _search with the following arguments.

self.root: This is the root of the binary search tree. The search starts from the root.

key: This is the value that the user wants to find in the binary search tree.

### Your code so far

```
class TreeNode:
def __init__(self, key):
self.key = key
self.left = None
self.right = None
class BinarySearchTree:
def __init__(self):
self.root = None
def _insert(self, node, key):
if node is None:
return TreeNode(key)
if key < node.key:
node.left = self._insert(node.left, key)
elif key > node.key:
node.right = self._insert(node.right, key)
return node
def insert(self, key):
self.root = self._insert(self.root, key)
# User Editable Region
def _search(self, node, key):
if node is None or node.key == key:
return node
if key < node.key:
return self._search(node.left, key)
return self._search(node.right, key)
def search(self, key):
_search(self.root,key)
# User Editable Region
```
