当我按下“获取”按钮时，它应该从列表框中抓取项目并将该项目放入“您正在携带”列表以及更新房间和列表框。
我正在考虑制作一个 updateWidget 函数，该函数将在获取 grabbable 后清除列表框，并在移动到另一个房间后用新的 grabbable 重新加载列表框。只是我不知道该怎么做。

Game.inventory.append(grabbable)
# remove the grabbable item from the room
Game.currentRoom.delGrabbable(grabbable)
# set the response (success)
response = "Item grabbed."
# no need to check any more grabbable items
break
# display the response on the right of the GUI
# display the room's image on the left of the GUI
# clear the player's input
self.setStatus(response)
self.setRoomImage()
Game.player_input.delete(0, END)
此代码将直接在流程函数中处理“take”动作，并在状态区显示可用的物品和玩家的库存。玩家可以输入“Take [item]”来获取物品，游戏会相应地更新房间和显示的物品。
