add input() after the maze has been generated will run the GUI

[OGTripleK]

Based on your aStarHeuristicComparison.py , I got it working as normal... it print into the terminal but after adding a = input() at the end of the code will trigger the GUI to show. For this file, for loop has been set to 100 which it will do comparison for 100 times without showing the GUI but the worst is if add input() after it generate the maze it will popup 100 GUI windows which may cause pc freezing depend on pc specs...
