题目二：遍历字典（入门）

描述

创建一个依次包含键-值对'<': 'less than'和'==': 'equal'的字典operators_dict，

先使用print()语句一行打印字符串'Here is the original dict:'，

再使用for循环遍历已使用sorted()函数按升序进行临时排序的包含字典operators_dict的所有键的列表，使用print()语句一行输出类似字符串'Operator < means less than.'的语句；

对字典operators_dict增加键-值对'>': 'greater than'后，

输出一个换行，再使用print()语句一行打印字符串'The dict was changed to:'，

再次使用for循环遍历已使用sorted()函数按升序进行临时排序的包含字典operators_dict的所有键的列表，使用print()语句一行输出类似字符串'Operator < means less than.'的语句，确认字典operators_dict确实新增了一对键-值对。

输入描述：

无

输出描述：

按题目描述进行输出即可（注意前后两个输出部分需以一个空行进行分隔）。

题目三：毕业生就业调查（中等）

描述

又到了毕业季，牛牛作为牛客大学的学生会主席，决定对本校的应届毕业生进行就业调查。

他创建了一个依次包含字符串'Niumei'、'Niu Ke Le'、'GURR'和'LOLO'的列表survey_list，作为调查名单；

又创建了一个依次包含键-值对'Niumei': 'Nowcoder'和'GURR': 'HUAWEI'的字典result_dict，作为已记录的调查结果。

请遍历列表survey_list，如果遍历到的名字已出现在包含字典result_dict的全部键的列表里，

则使用print()语句一行输出类似字符串'Hi, Niumei! Thank you for participating in our graduation survey!'的语句以表达感谢，

否则使用print()语句一行输出类似字符串'Hi, Niu Ke Le! Could you take part in our graduation survey?'的语句以发出调查邀请。

输入描述：

无

输出描述：

按题目描述进行输出即可。

Hi, Niumei! Thank you for participating in our graduation survey!
Hi, Niu Ke Le! Could you take part in our graduation survey?
Hi, GURR! Thank you for participating in our graduation survey!
Hi, LOLO! Could you take part in our graduation survey?
