創(chuàng)建了將人名用作鍵的字典，輸入姓名查找值，返回錯(cuò)誤。代碼：
people={
'Alice': {
'phone': '6789',
'addr': 'Ruan road 23'
},
'Mary':{
'phone': '8769',
'addr': 'Foo drive 66'
},
'Jay': {
'phone': '6666',
'addr': 'Bar street 88'
}
}
labels={
'phone':'phone number',
'addr':'address'
}
name=input('Name:')
request=input('phone number(p) or address(a)?')
if request=='p':key='phone'
if request=='a':key='addr'
if name in people: print("{}'s {} is {}.".format(name,labels[key],people[name][key]))
錯(cuò)誤：
