8. sum_binary_tree For this function, we are using a data structure called a binary tree, which is useful for storing all different kinds of data. In this problem a binary tree contains a single number, and it has two children, each of which may be either None, or they may be more binary trees. You can see, this is a recursively defined data structure! To recap: each binary tree contains a number and two children. The children are either None or a BinaryTree object. In this function we want to sum up all of the numbers contained in a binary tree and its children (recursively). Sample calls should look like this: »> sum_binary_tree(BinaryTree(10, None, None)) 10 >> sum_binary_tree(BinaryTree(10, None, BinaryTree(10, None, BinaryTree(10, None, None)))) 30 >>> sum_binary_tree(None)

![8. sum_binary_tree
For this function, we are using a data structure called a binary tree, which is useful for storing all different kinds of data.
In this problem a binary tree contains a single number, and it has two children, each of which may be either None, or
they may be more binary trees. You can see, this is a recursively defined data structure!
To recap: each binary tree contains a number and two children. The children are either None or a BinaryTree object.
In this function we want to sum up all of the numbers contained in a binary tree and its children (recursively).
Sample calls should look like this:
| >>> sum_binary_tree(BinaryTree(10, None, None))
10
>>> sum_binary_tree(BinaryTree(10, None, BinaryTree(10, None, BinaryTree(10, None, None))))
30
