Weighted a star. While coding weighted a star, path finder algorithm I have learned python OOP. I also used python dictionary for better performance. This aStar take as input size, difficulty (from 0 to 100), e (from 0 to 100) if e is small algorithm is taking longer but it returns better path in the opposite case algorithm is fast, but path isn't the best.

A* search algorithm - Wikipedia
https://en.wikipedia.org/wiki/A*_search_algorithm
A* (pronounced "A-star") is a graph traversal and path search algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. One major practical drawback is its space complexity, as it stores all generated nodes in memory. Thus, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance, as well as memory-bounded approaches; however, A* is …

Introduction. Many of the most effective algorithms in satisficing search have a weight parameter that can be used to govern the bal- ance between solution quality and search effort. The most famous of these is Weighted A* (Pohl 1970), which expands nodes in f′order, where f′(n) = g(n)+w· h(n) : w ∈ (1,∞).
