基于文本的游戲。主功能

所以我是個白癡，幾乎在 main 函式之外撰寫了 mina 代碼。我仍然是新手并且正在學習，所以當我將代碼移入主函式時，我無法訪問已定義的變數。我的位置和庫存，因為它們是在主函式中定義的，所以當我嘗試呼叫 status() 時無法正常作業。但是當我將庫存和位置移到主要功能之外時，庫存無法進入房間。任何人都可以指出我解決這個問題的正確方向。謝謝

uj5u.com熱心網友回復：

你可以

• 在 Main 中創建一個名為“倉庫”的物件，每個專案及其庫存都可以在倉庫物件中維護，因此您不需要將其作為子程式，和/或
• 您可以在代碼開始時在 main 或其他子例程之外創建“全域變數”，或者
• 您可以將一個變數傳遞給您的子例程（從 Main），并在子例程完成時將回傳值傳回給 main。

將它們作為引數傳遞實際上是解決方案。有人提到了這一點，這正是我所需要的。這是更新代碼

def status(location, inventory, rooms):
    print('-' * 20)
    print('You are in the {}'.format(location['name']))
    print('Your current inventory: {}\n'.format(inventory))
    if location['item']:
        print('Item in room: {}'.format(', '.join(location['item'])))
        print('')

然后在呼叫函式時我只是填寫了引數。

    # shows current location
        status(location, inventory, rooms)
