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]
