递归将字典嵌套排序并转化成字符串

Python递归练习

调用外部api接口需要排序好的字典形式的字符串,字典默认是带有空格的,所以需要处理,这里运用了递归的思想
主要运用到的几个关键:
1.字典是无序的
2.list是可以排序的
3.字典可以转换为tuple

# coding: utf-8

test = {
        "address1":"1 Stafford Crt.",
        "address2":"aaaaaaa",
        "city":"Bayswater North",
        "doorplateNumbers":"109",
        "emailAddress":"[email protected]",
        "phoneNum":"15900001111",
        "packageList":[
            {
