1. people = {
   
2.     'Alice': {
   
3.         'phone': '2341',
   
4.         'addr': 'Foo drive 23'
   
5.     },
   
6.     'Beth': {
   
7.         'phone': '9102',
   
8.         'addr': 'Bar street 42'
   
9.     },
   
10.     'Cecil': {
    
11.         'phone': '3158',
    
12.         'addr': 'Baz avenue 90'
    
13.     }
    
14. }
    
15. 
    
16. labels = {
    
17.     'phone': 'phone number',
    
18.     'addr': 'address'
    
19. }
    
20. 
    
21. name = raw_input('Name: ')
    
22. request = raw_input('Phone number (p) or address(a)? ')
    
23. 
    
24. if request == 'p': key = 'phone'
    
25. if request == 'a': key = 'addr'
    
26. 
    
27. 
    
28. if name in people:
    
29.     print "%s\'s %s is %s." % (name, labels[key], people[name[key]])

运行到最后一句的时候出现了错误

1. Traceback (most recent call last):
   
2.   File "C:/Python26/test", line 32, in <module>
   
3.     print "%s\'s %s is %s." % (name, labels[key], people[name[key]])
   
4. TypeError: string indices must be integers, not str
