How To Convert A List to A Tree in Python?

In this Python code, we will learn how to convert a list to a tree in Python. The tree is a graph data structure and is non-linear. If you want to store hierarchical data then it is used. A list can be converted into the tree using a recursive function that takes the head of the list or any node as input and depending on that will generate appropriate children during recursion till the last element becomes null.

def normalize(tree, row=0, col=0):
    try:
        node = tree[row][col]
        left  = normalize(tree, row+1, col*2)
        right = normalize(tree, row+1, col*2+1)
        return [node, left, right] if left or right else [node]
    except:
        return None # child index does not exist
