在python实例中初始化

打印时

class fase1(): 
   def __init__ (self, num, date, desc) 
       self.num = num 
       self.date = date 
       self.desc = desc 

class fase2(fase1): 
   def __init__(self, ele): 
      self.ele = [ele,[]] 
    def __str__(self): 
      return self.ele
    def addfase2(self, num, date, desc): 
      newfase = fase1() 
      self.ele[1].append(newfase) 


namefase2 = "FASE" 
cload = fase2 
cload.ele = namefase2 
cload.addfase2(10,"date","Desc")

['FASE'，[]

有人能帮我吗？

您有一个数组，其中包含

fase1

对象，该对象未在

addfase2

方法中初始化（您可能需要）

此外，如果将

\uuu str\uuu

方法添加到

fase1

，则将不再看到对象repr

def addfase2(self, num, date, desc): 
    newfase = fase1(num, date, desc)

---

或者诸如此类的帮助做什么？什么不起作用了？你的

\uu str\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

完全按照你的编程方式将

添加到
fase1
中，你将无法在输出中获得def addfase2(self, num, date, desc): 
    newfase = fase1(num, date, desc)

def __str__(self):
    return self.desc + ' ' + self.num + ' ' + self.date
