张驰皓2023-08-29 来自北京#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。展开作者回复: 抛开课程为了练习列表和字典的操作， 通讯录是一个列表，其中每个元素都是一个字典。这种结构确实在删除特定联系人时可能会遇到问题，因为您需要知道联系人在列表中的索引。 为了方便地添加、查询和删除联系人，我们可以将通讯录从列表更改为字典。这样，联系人的名字可以作为键，而与之关联的信息可以作为值。这会让增加、查询和删除操作变得更为简单和直观。 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']} } 这样就方便增删改查了

水里捞鱼2023-02-12 来自北京分析：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')1
