在Python中對多維json進行迭代

Question

對不起發佈不正確的格式，希望我現在的查詢很清楚。 我正在解析一個JSON，它基本上是我的框架的配置文件。 這是它的外觀： My JSON JSON Random Field's values

我的代碼：

def makeCombination(): 
data = schemaConfig["PostData"] 
out_json = [] 
for v1, v2, v3, v4, v5, v6 in product(data['size']['testing_type']['random'], data['start_index']['testing_type']['random'], data['campaign_sub_type']['testing_type']['random'], data['campaign_type']['testing_type']['random'], data['api_key']['testing_type']['random'], data['project_id']['testing_type']['random']): 
    out_json.append({'size': v1,'start_index': v2,'campaign_sub_type': v3,'campaign_type': v4,'api_key': v5, 'project_key': v6}) 
    return out_json 


def runRegressionFunc(): 
randomList = makeCombination() 
tempOutList = list() 
for comb in randomList: 
    tempDoc = dict() 
    for funcName in comb: 
     (key, val) = callOtherClasses(funcName) 
     tempDoc[key] = val 
    tempOutList.append(tempDoc) 

return tempOutList 

我想從makeCombination（所有領域的「隨機」所有可能的組合），這回runRegressionFunc（） 。

P.S.我是新編碼世界:)

首先，你的json是不正確的。修復語法後，可以使用itertools.product獲取api_key和project_key的所有內容組合，並根據需要創建新的字典列表。

>>> from itertools import product 
>>> import pprint 
>>> 
>>> json_data = {"PostData" : { 
... "api_key": { 
... "data_type": "String", 
... "testing_type": { 
...  "random": [ 
...  "veryShortString", 
...  "shortString", 
...  "longString" 
...  ]}}, 
... 
... "project_key": { 
... "data_type": "String", 
... "testing_type": { 
...  "random": [ 
...  "veryShortString", 
...  "shortString", 
...  "longString" 
...  ]}}}} 
>>> 
>>> data = json_data['PostData'] 
>>> out_json = [] 
>>> for v1, v2 in product(data['api_key']['testing_type']['random'], data['project_key']['testing_type']['random']): 
...  out_json.append({'api_key' : v1, 'project_key' : v2 }) 
... 
>>> 
>>> pprint.pprint(out_json) 
[{'api_key': 'veryShortString', 'project_key': 'veryShortString'}, 
{'api_key': 'veryShortString', 'project_key': 'shortString'}, 
{'api_key': 'veryShortString', 'project_key': 'longString'}, 
{'api_key': 'shortString', 'project_key': 'veryShortString'}, 
{'api_key': 'shortString', 'project_key': 'shortString'}, 
{'api_key': 'shortString', 'project_key': 'longString'}, 
{'api_key': 'longString', 'project_key': 'veryShortString'}, 
{'api_key': 'longString', 'project_key': 'shortString'}, 
{'api_key': 'longString', 'project_key': 'longString'}]
