如何向類添加其他屬性？

Question

程序運行時，如何在列表中添加其他locationx和locationy變量？

該類的示例：

class Building:
    'Common base class for all buildings'

    def __init__(self, name, hp, img, locationx, locationy, height, width):
        self.name = name
        self.hp = hp
        self.img = img
        self.locationx = locationx
        self.locationy = locationy
        self.height = height
        self.width = width

building_shipyard = Building("Shipyard",500,shipyard,[1000,2500,5000],[1000,2500,5000],300,300)

例如，在用戶放置新建築物之后，我可能希望將self.locationx和self.locationy從[1000,2500,5000]更新為[1000,2500,5000,7000]。

Answer 1

只需訪問以下屬性：

...
def place_building ():
    global building_shipyard 
    ...
    building_shipyard.locationx =  [1000,2500,5000,7000]
    # or
    building_shipyard.locationx.append(7000)
