将python2初始化的字典源代码转为有序字典的代码

python2有序字典为

from collections import OrderedDict
od = OrderedDict()

python3.6以后的dict默认就是有序的，所以这里的方案是使用python3.7将源字典生成新的逻辑：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

A = {"MC_SYNCMODE":"112",
     "AAA":[12,34,],
     "CVCC":{"SDSD":{"dwqd":"eee"}}}

print("od = OrderedDict()")

def SetOrderedDict(dict1,preName):
    for key in dict1:
        if type(dict1[key]) == dict:
            print('{}["{}"]'.format(preName,key) + " = OrderedDict()")
            SetOrderedDict(dict1[key],'{}["{}"]'.format(preName,key))
        elif type(dict1[key]) == str:
            print('{}["{}"]'.format(preName,key) + " = " + '"{}"'.format(dict1[key]))
        else:
            print('{}["{}"]'.format(preName,key) + " = " + '{}'.format(dict1[key]))


SetOrderedDict(A,"od")

输出：

od = OrderedDict()
od["MC_SYNCMODE"] = "112"
od["AAA"] = [12, 34]
od["CVCC"] = OrderedDict()
od["CVCC"]["SDSD"] = OrderedDict()
od["CVCC"]["SDSD"]["dwqd"] = "eee"
