python - 我不知道如何让这门课正常工作

Question

您好，我正在尝试制作国际象棋游戏，但是我似乎无法让这个类工作，我如何在主块中更改变量 pawn_black1_status 在我在类中更改它后进行更改？如果它工作正常，它应该打印“dead”

class Status(object):
    def __init__(self,piece,pawn_black1_status):
        self.piece=piece
        self.pawn_black1_status=pawn_black1_status
    def Status2(self,piece,pawn_black1_status):
        self.piece=piece
        self.pawn_black1_status=pawn_black1_status
        self.pawn_black1_status="dead"
        
pawn_black1_status="alive"
Pawn1b_status=Status("p1b",pawn_black1_status)
Pawn1b_status.Status2("p1b",pawn_black1_status)
print(pawn_black1_status)

您必须引用您创建的类才能访问其中的变量。

class Status(object):
    def __init__(self,piece,pawn_black1_status):
        self.piece=piece
        self.pawn_black1_status=pawn_black1_status
    def Status2(self,piece,pawn_black1_status):
        self.piece=piece
        self.pawn_black1_status=pawn_black1_status
        self.pawn_black1_status="dead"
        
pawn_black1_status="alive"
Pawn1b_status=Status("p1b",pawn_black1_status)
Pawn1b_status.Status2("p1b",pawn_black1_status)
print(Pawn1b_status.pawn_black1_status)
