python - python实例中的类

Question

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")

当打印...

['FASE',[<__main__.fase1 instance at 0x01C2BEB8>]]

谁能帮帮我？

Answer 1

你有一个包含你的对象的数组fase1，它没有在你的addfase2方法中初始化（你可能想要）

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

此外，如果您向 中添加__str__方法fase1，您将不会再看到对象 repr

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