py2.0如果要在一行打印字符串和表达式计算出的值该怎么写呢？

1. class CounterList(list):
   
2.     def __init__(self,*args):
   
3.         super(CounterList,self).__init__(*args)
   
4.         self.counter=0
   
5.     def __getitem__(self, index):
   
6.         self.counter+=1
   
7.         return super(CounterList, self).__getitem__(index)
   
8. 
   
9. 
   
10. c1=CounterList(range(10))
    
11. # print c1
    
12. # c1.reverse()
    
13. # print c1
    
14. del c1[3:6]
    
15. print c1
    
16. print c1.counter
    
17. print c1[4]+c1[2]
    
18. print 'c1.counter:'+c1.counter

我按照java的写法，最后一行报错了，该怎么改呢？
