如何讓單詞打印為整個單詞？

Question

我正在使用下面的代碼完成我的第一個 Python 編程課程的最終項目。 其中大部分已經有效。 這個想法是一個基於文本的冒險游戲，你需要在到達“老板室”之前收集 6 件物品。 唯一給我帶來問題的是狀態功能，它旨在打印玩家庫存。 然而，當玩家去收集第一件物品時，它不會打印物品欄：[自畫像]，而是物品欄：['S', 'e', 'l', 'f', ' ', 'P', 'o'、'r'、't'、'r'、'a'、'i'、't']。 不知道如何解決這個問題，盡管這似乎是一個愚蠢的問題，哈哈，但我是初學者！ 我的完整代碼如下。

def instructions():
    print('You are taking part in a museum heist!')
    print("Collect all 6 paintings before you find your mafia boss, or you will get fired!")
    print("To move, type: North, South, East, or West.")
    print("To collect an item, type: Collect")
    print('To quit, type Quit')

instructions()
print('----------------------')


def status():

    print('You are in the', current_room, 'Room')
    print('Inventory:', str(inventory))
    if 'item' in rooms[current_room]:
        print('You see an artwork called', str(rooms[current_room]['item']))


print('----------------------')

inventory = []#placeholders
item = ' '

def main():

    inventory = []


rooms = {
    'Foyer': {'East': 'Contemporary'},
    'Contemporary': {'North': 'Impressionist', 'East': 'Abstract', 'West': 'Foyer', 'South': 'Surrealist', 'item': 'Self Portrait'},
    'Abstract': {'North': 'Pop Art', 'West': 'Contemporary', 'item': 'Convergence'},
    'Pop Art': {'South': 'Abstract', 'item': 'Shot Marilyns'},
    'Surrealist': {'North': 'Contemporary', 'East': 'Realist', 'item':  'The Persistence of Memory'},
    'Impressionist': {'South': 'Contemporary', 'East': 'Expressionist', 'item': 'Poppies'},
    'Expressionist': {'West': 'Impressionist', 'item': 'Starry Night'},
    'Realist': {'West': 'Surrealist', 'item': 'Mafia Boss'}
}

current_room = 'Foyer'

while True:
    status()
    if rooms[current_room] == rooms['Realist']:
        print('Oh no! Your boss is angry you did not steal all the paintings! You have been fired. GAME OVER.')
        break
    if len(inventory) == 6:
        print('Congratulations! You got all the paintings. You Win!!')
        break
    print('----------------------')
    print('Which way?')
    move = input()
    if move == 'Quit':
        print('Sorry to see you go!')
        break
    elif move == 'Collect':
        if 'item' in rooms[current_room]:
            inventory += str(rooms[current_room]['item'])
            print("You collected", str(rooms[current_room]['item']))
            del rooms[current_room]['item']
        else:
            print('There is no item here.')
    elif move == 'North' or 'South' or 'East' or 'West':
        if move in rooms[current_room]:
            current_room = rooms[current_room][move]
        else:
            print("Sorry, you can't go that way.")
            move = input()
            current_room = current_room
    else:
        print('Invalid move!')

Answer 1

首先，您可以使用print()查看不同時刻變量中的內容 - 這樣您就可以看到在哪個時刻創建['S', 'e', 'l', 'f', ' ', 'P', 'o', 'r', 't', 'r', 'a', 'i', 't']

您添加新項目使用

inventory += ...

但這是捷徑

inventory.extend( other_list )

它期望列表作為參數，但您有字符串Self Portrait ，Python 可以將其視為字符列表。

你應該使用.append()

inventory.append( item )

或者您應該將列表與item

inventory.extend( [item] )

inventory += [item]

---

我看到其他問題。

它應該是

elif move == 'North' or move == 'South' or move == 'East' or move == 'West':

或者

elif move in ('North', 'South', 'East', 'West'):

---

因為我不喜歡寫長的單詞並且使用shift所以我會這樣做

    if move.lower() in ('quit', 'q'):
        #...code...     
    elif move.lower() in ('collect', 'c'):
        #...code...     

現在玩家可以使用Quit 、 quit 、 QUIT 、 QuIt等，或者簡單地使用q或Q 。 Collect 。

我會對'North', 'South', 'East', 'West'做同樣的事情'North', 'South', 'East', 'West'但你在字典rooms使用它，所以我會使用其他字典將短e轉換為長East等。

shortcuts = {
    'n': 'North',
    's': 'South',
    'e': 'East',
    'w': 'West',
}

while True:

    # ... code ...

    move = input()
    
    move = shortcuts.get(move.lower(), move)

    # ... code ...

如果它在快捷方式中找到move.lower() - 即。 e - 然后它得到全名 - 即。 East 。 但是它沒有在shortcuts找到較低的文本，然后它保持原始值不被move （ get()第二個參數）

完整的工作代碼。

為了使代碼更具可讀性，我將所有函數放在開頭。

# --- functions ---

def instructions():
    print('You are taking part in a museum heist!')
    print("Collect all 6 paintings before you find your mafia boss, or you will get fired!")
    print("To move, type: North, South, East, or West.")
    print("To collect an item, type: Collect")
    print('To quit, type Quit')

def status():
    print('You are in the', current_room, 'Room')
    #print('Inventory:', inventory)
    print('Inventory:', ', '.join(inventory))

    if 'item' in rooms[current_room]:
        print('You see an artwork called', rooms[current_room]['item'])

def main():
    global inventory
    
    inventory = []

# --- main ---

# - variables -

inventory = []#placeholders
item = ' '

rooms = {
    'Foyer': {'East': 'Contemporary'},
    'Contemporary': {'North': 'Impressionist', 'East': 'Abstract', 'West': 'Foyer', 'South': 'Surrealist', 'item': 'Self Portrait'},
    'Abstract': {'North': 'Pop Art', 'West': 'Contemporary', 'item': 'Convergence'},
    'Pop Art': {'South': 'Abstract', 'item': 'Shot Marilyns'},
    'Surrealist': {'North': 'Contemporary', 'East': 'Realist', 'item':  'The Persistence of Memory'},
    'Impressionist': {'South': 'Contemporary', 'East': 'Expressionist', 'item': 'Poppies'},
    'Expressionist': {'West': 'Impressionist', 'item': 'Starry Night'},
    'Realist': {'West': 'Surrealist', 'item': 'Mafia Boss'}
}

shortcuts = {
    'n': 'North',
    's': 'South',
    'e': 'East',
    'w': 'West',
}

current_room = 'Foyer'

# - code -

instructions()
print('----------------------')

while True:
    status()
    if rooms[current_room] == rooms['Realist']:
        print('Oh no! Your boss is angry you did not steal all the paintings! You have been fired. GAME OVER.')
        break
    if len(inventory) == 6:
        print('Congratulations! You got all the paintings. You Win!!')
        break
    print('----------------------')

    print('Which way?')
    move = input()
    
    move = shortcuts.get(move.lower(), move)
    print('[DEBUG] move:', move)
    
    if move.lower() in ('quit', 'q'):
        print('Sorry to see you go!')
        break
    
    elif move.lower() in ('collect', 'c'):
        if 'item' in rooms[current_room]:
            inventory.append(rooms[current_room]['item'])
            print("You collected", rooms[current_room]['item'])
            del rooms[current_room]['item']
        else:
            print('There is no item here.')

    elif move.lower() in ('north', 'south', 'east', 'west'):
        if move in rooms[current_room]:
            current_room = rooms[current_room][move]
        else:
            print("Sorry, you can't go that way.")
            #move = input()
