1、dumps：将python中的 字典 转换为 字符串
import jsontest_dict = {'bigberg': [7600, {1: [['iPhone', 6300], ['Bike', 800], ['shirt', 300]]}]}print(test_dict)print(type(test_dict))#dumps 将数据转换成字符串json_str = json.dumps(test_dict)print(json_str)print(type(json_str))2、loads: 将 字符串 转换为 字典
new_dict = json.loads(json_str)print(new_dict)print(type(new_dict))3、dump: 将数据写入json文件中
with open("../config/record.json","w") as f: json.dump(new_dict,f) print("加载入文件实现...")4、load:把文件关上，并把字符串变换为数据类型
with open("../config/record.json",'r') as load_f: load_dict = json.load(load_f) print(load_dict)load_dict['smallberg'] = [8200,{1:[['Python',81],['shirt',300]]}]print(load_dict)with open("../config/record.json","w") as dump_f: json.dump(load_dict,dump_f)5、遍历key value
test_json = {"a":1,"b":2,"c":3}for key,value in test_json.items(): print key,value
