My Dungeon game code isn't working any help would be appreciated.

# draw grid
# random location for player
# random location for exit door
# random location for monster  <<<<<maybe make random type of monster>>>>>
# draw player
# take input for movement
# move player, unless invalid move
# check for win/loss
# clear screen and redraw board
