Question

所以我是个白痴，几乎在 main 函数之外编写了 mina 代码。我仍然是新手，正在学习，所以当我将代码移入 main 函数时，我失去了对已定义变量的访问权限。我的位置和库存因为它们是在主要功能中定义的，所以当我尝试调用 status() 时无法正常工作。但是当我将库存和位置移到主要功能之外时，库存无法访问房间。谁能指出我解决这个问题的正确方向。谢谢

def instructions():
 print("\n      Super Humans Adventure Game")
 print("-------------Instructions-------------")
 print("Collect the 6 items within the rooms to")
 print("defeat the scientist and win.")
 print("To move type: North, South, West, or East")
 print('-' * 38)


def status():
 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('')

def main():
 rooms = {

Answer 1

你可以

在 Main 中创建一个名为“仓库”的对象，每个项目及其库存都可以在仓库对象中维护，因此您不需要它是一个子例程，and/or
您可以在主程序或其他子程序之外创建“全局变量”以在代码启动时定义，或者
您可以将变量传递给您的子例程（从 Main），并在子例程完成时将 return 值传回给 main。

Answer 2

将它们作为参数传递实际上是解决方案。有人提到了这一点，这正是我所需要的。这是更新代码

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('')

然后在调用函数的时候我只填了参数就可以了

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