info = {
’stu1101‘ ： ’xiaoming’，
‘stu1102 ： xiahong‘,
’stu1103 ： ‘xiaozhi',
}
1. 字典的获取
info.get('stu1104') # 有就获取，没有就返回none
2. 字典的跟新
b = {'stu1101', 'Alex',
3:5,
1:2,
}
info.update(b)
print(info)
3.字典的显示
info.items()
info.keys()
info.values()
4.初始化字典
c = dict.fromkeys([6, 7, 8], 'test')
5. 字典替换
info['stu1101'] = 'xiaogang'
6.字典创建
info['stu1104'] = 'xiaohua'
7.字典删除
del info['stu1101']
info.pop('stu1101')
8.字典循环
for i in info:
print(i, info(i))
