Python题，我真的对标题设置无语😓

编写interchange_dict()，函数功能是交换字典的key和value，获得新字典，然后按照新字典的key值降序输出内容。

dict = {610065:'SCU',611731:'UESTC',610225:'CUIT'}
newdict = { v:k for k,v in dict.items() }
print(newdict)

d = {'a': 1,'c': 66,'b': 3,"zz": 34,}
d1 = {v: k for k, v in d.items()}

print(dict(sorted(d1.items(), key=lambda x: x[0], reverse=False)))
