python json 递归打印所有json子节点信息的例子

我就废话不多说了，直接上代码吧

def json_txt(self, dic_json):
 #self.debug_print("json_txt")
 if isinstance(dic_json, dict): # 判断是否是字典类型isinstance 返回True false
  for key in dic_json:
   #dic_json = json.loads(s)
   s = dic_json[key]
   #self.debug_print(str(len(s)) + " type:" + str(type(s)))
   t=str(type(s))
   if t.startswith("<class 'list'>"):
    for i in range(0, len(s)):
     self.debug_print("%s %d:" % (key, i))
     self.json_txt(s[i])
   else:
    self.debug_print("%s: %s" % (key, s))
 else:
  self.debug_print("else")

补充拓展：python求json某层节点的和实例

如下所示：

import json

from collections import Mapping

import json

def dict_generator(indict, pre=None):
pre = pre[:] if pre else []
if isinstance(indict, dict):
for key, value in indict.items():
if isinstance(value, dict):
if len(value) == 0:
yield pre+[key, ‘{}']
else:
for d in dict_generator(value, pre + [key]):
yield d
elif isinstance(value, list):
if len(value) == 0:
yield pre+[key, ‘[]']
else:
for v in value:
for d in dict_generator(v, pre + [key]):
yield d
elif isinstance(value, tuple):
if len(value) == 0:
yield pre+[key, ‘()']
else:
for v in value:
for d in dict_generator(v, pre + [key]):
yield d
else:
yield pre + [key, value]
else:
yield indict

def recursive_findall(obj, key, paths=None):
ret = []
if not paths:
paths = []
if isinstance(obj, Mapping):
for k, v in obj.iteritems():
found_items = recursive_findall(v, key, paths=(paths + [(‘k', k)]))
ret += found_items
elif isinstance(obj, (list, tuple)):
for i, v in enumerate(obj):
found_items = recursive_findall(v, key, paths=(paths + [(‘i', i)]))
ret += found_items
else:
if key(obj):
ret.append((paths, obj))
return ret

ret_dict = {
“data”:[
{
“email”:"",
“repoCommits”:[
{
“branchCommitLine”:[
{
“submitLine”:1
},
{
“submitLine”: 1
}]},
{
“branchCommitLine”: [
{
“submitLine”: 1
},
{
“submitLine”: 1
}]}]

        },
 {
  "email": "",
  "repoCommits": [
   {
    "branchCommitLine": [
     {
      "submitLine": 1
     },
     {
      "submitLine": 1
     }]},
   {
    "branchCommitLine": [
     {
      "submitLine": 1
     },
     {
      "submitLine": 1
     }]}]

 }



    ]
   }

if name == ‘main':

all_socre = 0
for da in ret_dict["data"]:
 if da.has_key("repoCommits"):
  for repo in da["repoCommits"]:
   if repo.has_key("branchCommitLine"):
    for branch in repo["branchCommitLine"]:
     if branch.has_key("submitLine"):
      all_socre += int(branch["submitLine"])
     else:
      continue
   else:
    continue
 else:
  continue
ret = dict_generator(ret_dict)
print(ret)
for i in ret:
 print i[-1]
