Python 字典练习

一、现有字典info={'name':'大锤','hobby':'study','gender':1}

2. 发现年龄有误，应该是 20 岁，如何修改
3. 现需要增加住址为杭州的信息

7. 如何清空字典info的所有信息

9. 因为没有发现年龄先增加一个年龄
   Info[age]=12;修改lnfo[age]=20
10. info[address]=’杭州’
11. Del.info[age]
12. print(info.pop(‘address’))
13. new_dict.update(old_dict)
14. info.clear(),##清空所有的条目
    del,info ##删除词典
