这个怎么打印出日期结果？

sayid_python

1. import  time
   
2. 
   
3. class Date(object):
   
4.         def __init__(self,year,month,day):
   
5.                 self.year = year
   
6.                 self.month = month
   
7.                 self.day = day
   
8.         @staticmethod
   
9.         def now():
   
10.                 t = time.localtime()
    
11.                 return Date(t.tm_year,t.tm_mon,t.tm_mday)
    
12.         @staticmethod
    
13.         def tomorrow():
    
14.                 t = time.localtime(time.time() + 86400)
    
15.                 return Date(t.tm_year,t.tm_mon,t.tm_mday)
    
16. 
    
17. a = Date(1967,4,9)
    
18. b = Date.now()
    
19. c = Date.tomorrow()
    
20. 
    
21. print b
    
22. print c

复制代码

现在打印的是
<__main__.Date object at 0x01A75B90>
<__main__.Date object at 0x01A75BB0>
