#新增一个列表来存放通讯录内容 address_book=[{'allen':{'name':'allen','nickname':'','email':'allen@123.com','phone':['187','137']}}, {'jack':{'name':'jack','nickname':'jackchen','email':'jack@123.com','phone':['187','137']}}] print(address_book) #在通讯录列表里插入一个联系人（插入内容是字典时，不能直接用 append 方法，需要先把字段赋值给一个变量然后再用 append） mary={'mary': {'name': 'mary', 'nickname': 'mali', 'email': 'mary@123.com', 'phone': ['187', '137']}} address_book.append(mary) print(address_book) #删除一个联系人 result=address_book.pop(2) print(result) print(address_book) 发现一个问题，在删联系人的时候，如果要删一个指定且不知道在列表里位置的联系人，用现在这个数据结构好像是不太好做到的。

address_book = {'Cecilia': [{'Nickname': 'Cici'}, {'Email':'cici@123.com'}, {'Number': [1234567, 9999999]}]} print(address_book) # 增加联系人 address_book.setdefault('Elizabeth', [{'Nickname': None}, {'Email':'liz@123.com'}, {'Number': [6666666, 7777777]}]) print(address_book) # 删除联系人 address_book.pop('Elizabeth') print(address_book)

# 设计一个字典数据类型用于存储通讯录，通讯录中包含：必须填写的姓名、可以为空的备注名、1 个邮箱，至少 2 个手机号码，并尝试增加和删除联系人。 address_book = [ {'name': 'John Smith', 'nickname': 'Johnny', 'email': 'john.smith@example.com', 'phone_number': ['+1 555-123-4567', '+1 555-987-6543']}, {'name': 'Emily Davis', 'nickname': 'Em', 'email': 'emily.davis@example.com', 'phone_number': ['+1 555-777-8888']} ] # create new_user = {'name': 'Bob Johnson', 'nickname': 'Bobby', 'email': 'bob.johnson@example.com', 'phone_number': ['+1 555-333-4444', '+1 555-555-5555']} address_book.append(new_user) print(json.dumps(address_book, indent=4)) # delete for item in address_book: if item.get('nickname') == 'Andrew': address_book.remove(item) print(json.dumps(address_book, indent=4)) # update for index, item in enumerate(address_book): if item['nickname'] == 'Em': address_book[index]['phone_number'][0] = '+2 222-1234-1234' print(json.dumps(address_book, indent=4))

分析：假定一条记录用字典来存储，每条记录中包含姓名（字符串）、备注名（列表of字符串，可能有多个或0个）、邮箱（假定只有一个，字符串）、手机号（至少2个，用列表）。多条记录用字典存储，假定没有重名用户。 因此： 1. contactinfo_records = dict() 2. contactinfo = {'contact_name': 'jojo', 'alias':[], 'email': "jojo@jojo.com", 'phone_nums': [xxx,xxx]} 3. 添加：contactinfo_records['jojo'] = contactinfo 4. 删除：contactinfo_records.pop('jojo')
