如何向类添加其他属性？

Question

在程序运行时，我会如何向列表中添加附加的locationx和位置变量？类的

例子：

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，用户将新大楼后，我可能要self.locationx和self.locationy从[1000,2500,5000]进行更新[ 1000,2500,5000,7000。

刚刚接触这些属性：

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