Write a Python Program to implement A* Algorithm.

To implement the A* algorithm in Python, we need to define the key components: the start node, the goal node, the cost of movement, and a heuristic to estimate the cost from any node to the goal. The A* algorithm combines the actual cost to reach a node and the heuristic estimate to find the most optimal path. Here’s how you can implement it:

 import heapq class Node: def __init__(self, name, parent=None, g=0, h=0): self.name = name self.parent = parent self.g = g # Cost to reach this node self.h = h # Heuristic cost estimate to goal self.f = g + h # Total cost (f =  _______ _______ ______ _____ _________ ___.
