分别获取字典的key列表和value列表
data = {'语文':'95', '数学':'95', '英语':'90'} keys = list(data.keys()) values = list(data.values()) print('keys列表:\n',keys) print('values列表:\n',values)keys列表: [‘语文’, ‘数学’, ‘英语’] values列表: [‘95’, ‘95’, ‘90’]
获取字典key和value值
data = {'语文':'95', '数学':'95', '英语':'90'} for key,value in data.items(): print(key, value)语文 95 数学 95 英语 90
列表构造字典：
key_list = ['语文', '数学', '英语'] value_list = ['95', '95', '90'] data = dict(zip(key_list,value_list)) print(data){‘语文’: ‘95’, ‘数学’: ‘95’, ‘英语’: ‘90’}
cookies构造字典
