Logging not working

I have the exact same code as Kenneth and yet I'm still able to see the 'X'. What am I doing wrong? I've tried running the code on other text editors and it's the same result. Calling game.log shows me that locations for monster, door, and player are logged, but has no affect in hiding it when the code is run.

import logging
import random

logging.basicConfig(filename='game.log', level=logging.DEBUG)

player = {'location': None, 'path': []}
cells = [(0, 0), (0, 1), (0, 2),
         (1, 0), (1, 1), (1, 2),
         (2, 0), (2, 1), (2, 2)]

def get_locations():
    monster = random.choice(cells)
    door = random.choice(cells)
    start = random.choice(cells)

    if monster == door or monster == start or door == start:
        monster, door, start = get_locations()

    return monster, door, start

def get_moves(player):
    moves = ['LEFT', 'RIGHT', 'UP', 'DOWN']
    if player in [(0, 0), (1, 0), (2, 0)]:
    if player in [(0, 0), (0, 1), (0, 2)]:
    if player in [(0, 2), (1, 2), (2, 2)]:
    if player in [(2, 0), (2, 1), (2, 2)]:
    return moves

def move_player(player, move):
    x, y = player['location']
    player['path'].append((x, y))
    if move == 'LEFT':
        player['location'] = x, y - 1
    elif move == 'UP':
        player['location'] = x - 1, y
    elif move == 'RIGHT':
        player['location'] = x, y + 1
    elif move == 'DOWN':
        player['location'] = x + 1, y
    return player

def draw_map():
    print(' _ _ _')
    tile = '|{}'
    for idx, cell in enumerate(cells):
        if idx in [0, 1, 3, 4, 6, 7]:
            if cell == player['location']:
                print(tile.format('X'), end='')
            elif cell in player['path']:
                print(tile.format('.'), end='')
                print(tile.format('_'), end='')
            if cell == player['location']:
            elif cell in player['path']:

monster, door, player['location'] = get_locations()'monster: {}; door: {}; player: {}'.format(
        monster, door, player['location']))

while True:
    moves = get_moves(player['location'])
    print("Welcome to the dungeon!")
    print("You're currently in room {}".format(player['location']))


    print("\nYou can move {}".format(', '.join(moves)))
    print("Enter QUIT to quit")

    move = input("> ")
    move = move.upper()

    if move == 'QUIT':

    if not move in moves:
        print("\n** Walls are hard! Stop running into them! **\n")

    player = move_player(player, move)
    if player['location'] == door:
        print("\n** You escaped! **\n")
    elif player['location'] == monster:
        print("\n** You got eaten! **\n")

Great question!! On first glance I’m wondering why Kenneth’s code doesn’t produce an “X”. And I've finally figured it out.

TL;DR: Logging works, your code is fine. Kenneth's code in video has a bug (bad if comparison)

In the video code, there is a bug in the draw_map function. The blocks of code under the ifand else sections are not the same. The if block uses:

if cell == player['location']:

the else block uses:

if cell == player:

The latter comparison will always fail because cell is a tuple and player is a dict.

In copying the code, you used the correct comparison to player['location'].

Post back if you have more questions. Good luck!!
