Maze program done in Y1S1

In my first year of studying in the school of ICT, I have learnt basic python programming skills, and created a project which allows me to use a PI to play a maze game, with the inclusion of other elements such as a key and a door in the maze.

In that picture above, the aim is to move marker A to Marker B, with X being the walls and O being open paths. The Door, "D" will act as a wall until the A marker collects a key, which will allow A to move past the D marker like it is a open path.
