Как я могу указать общую (x, y) позицию в списках Python?

Question

Я должен сделать игру-лабиринт с матрицей в качестве лабиринта.Я хочу иметь возможность перемещать игрока (X) вверх / вниз / вправо / влево.Для этого мне нужно определить координаты x, y массива, чтобы соответственно переместить их.Как я могу указать общую позицию в массиве?

Это мой лабиринт («1» представляет стену, а «X» - игрок):

level = [
    ["1","X","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"],
    ["1"," "," ","1","1","1","1","1","1","1"," "," "," "," "," "," "," "," "," "," ","1","1","1","1","1"],
    ["1"," "," ","1","1","1","1","1","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," "," "," ","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1","1","1"," "," "," "," "," "," ","1"],
    ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"," ","1"]
]

start_maze = level[0][1]
end_maze = level[9][23]
print(start_maze)
print(end_maze)

for bla in level:
    print(' '.join(str(n) for n in bla))

Итак, выводлабиринт: Лабиринт

Я хочу сказать, что игрок находится в положении "бла".Если игрок выбирает движение вверх, это означает, что позиция теперь становится -1 в направлении x и остается такой же в направлении y ... Надеюсь, я достаточно ясен ... Я новичок в Python.(Использование Python 3, кстати)

Это то, что я пытался изначально, но это не сработало (Это для продвижения вверх):

 #--MOVE = UP--
    if move == "UP":
        print(move)
        for y in range(0,len(level)):
            for x in range(0,len(level[y])):
                if level[y][x] == " ":
                    level[y][x] = level[y-1][x]
                    level[y][x] = "X"
                    print(level)
                else:
                    print('Oups - there is a wall there.')
                    try_again = input('Try Again? Y for Yes, N for No: ')
                    try_again = try_again.upper()
                    if try_again == 'Y':
                        continue           
                    else:
                        start = False       #to exit the loop and quit the program

Чтобы решить эту проблему, вам действительно нужно хранить координаты местоположения игрока в переменной.Вы правы, что ваши петли for не нужны.Вот один из способов сделать эту работу, надеюсь, комментарии помогут вам понять.Вероятно, его можно сделать более плавным, но он должен охватывать большинство необходимых вам функций.

level = [
    ["1"," ","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"],
    ["1"," "," ","1","1","1","1","1","1","1"," "," "," "," "," "," "," "," "," "," ","1","1","1","1","1"],
    ["1"," "," ","1","1","1","1","1","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," "," "," "," "," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," ","1","1","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," ","1","1","1","1"," "," ","1","1"," "," "," "," ","1","1","1","1"," "," ","1","1","1","1","1"],
    ["1"," "," ","1","1","1"," "," "," "," "," "," "," "," ","1","1","1","1"," "," "," "," "," "," ","1"],
    ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"," ","1"]
]

def print_level(level):
    """ Print level row-wise so that it retains its 2D shape """
    for row in level:
        print(row)

# Object to store the player coords
player = {'y': 0, 'x': 1}
level[player['y']][player['x']] = 'X'
print_level(level)

# Translate keywords into coordinate changes
move_modifications = {'UP': {'y': -1, 'x': 0},
                      'DOWN': {'y': 1, 'x': 0},
                      'LEFT': {'y':0, 'x': -1},
                      'RIGHT': {'y': 0, 'x': 1}}

# Main game loop
while True:
    move = input("Which direction?")

    # Give them the option to quit
    if move.lower() == 'exit':
        break

    if not move_modifications.get(move):
        print("Invalid input")
        continue

    coords = move_modifications[move]

    new_y = player['y'] + coords['y']
    new_x = player['x'] + coords['x']

    # Catch them if they try to leave the map
    try:
        maze_position = level[new_y][new_x]
    except IndexError:
        print("Not on map")
        continue

    if maze_position != '1':
        # Move on the map
        level[player['y']][player['x']] = ' '
        level[new_y][new_x] = 'X'

        # Update player coords
        player['y'] = new_y
        player['x'] = new_x

        # Print result
        print_level(level)
    else:
        print("Oops, there's a wall")

Если вы хотите напечатать только область вокруг проигрывателя, вы можете использовать что-то вроде следующей функции, используя списокнарезка.Это только примерный подход, который вы можете использовать в качестве отправной точки.

def print_window(level, player_y, player_x, window_size=2):
    """ Print only the immediate surroundings of the player """
    min_y = max(0, player_y - window_size)
    max_y = min(len(level), player_y + window_size)

    min_x = max(0, player_x - window_size)
    max_x = min(len(level[0]), player_x + window_size)

    for row in level[min_y:max_y]:
        print(row[min_x:max_x])
