本文实例讲述了python实现class对象转换成json字典的方法。分享给大家供大家参考，具体如下：

# -*- encoding: UTF-8 -*-
class Student:
  name = \'\'
  age = 0
  def __init__(self, name, age):
    self.name = name
    self.age = age
def convert_to_dict(obj):
  \'\'\'把Object对象转换成Dict对象\'\'\'
  dict = {}
  dict.update(obj.__dict__)
  return dict
def convert_to_dicts(objs):
  \'\'\'把对象列表转换为字典列表\'\'\'
  obj_arr = []
  for o in objs:
    #把Object对象转换成Dict对象
    dict = {}
    dict.update(o.__dict__)
    obj_arr.append(dict)
  return obj_arr
def class_to_dict(obj):
  \'\'\'把对象(支持单个对象、list、set)转换成字典\'\'\'
  is_list = obj.__class__ == [].__class__
  is_set = obj.__class__ == set().__class__
  if is_list or is_set:
    obj_arr = []
    for o in obj:
      #把Object对象转换成Dict对象
      dict = {}
      dict.update(o.__dict__)
      obj_arr.append(dict)
    return obj_arr
  else:
    dict = {}
    dict.update(obj.__dict__)
    return dict
stu = Student(\'zhangsan\', 20)
print \'-----------\'
print convert_to_dict(stu)
print \'-----------\'
print convert_to_dicts([stu, stu])
print \'-----------\'
print class_to_dict(stu)
print \'-----------\'
print class_to_dict([stu, stu])
stua = Student(\'zhangsan\', 20)
stub = Student(\'lisi\', 10)
stu_set = set()
stu_set.add(stua)
stu_set.add(stub)
print class_to_dict(stu_set)

运行结果如下：

-----------
{\'age\': 20, \'name\': \'zhangsan\'}
-----------
[{\'age\': 20, \'name\': \'zhangsan\'}, {\'age\': 20, \'name\': \'zhangsan\'}]
-----------
{\'age\': 20, \'name\': \'zhangsan\'}
-----------
[{\'age\': 20, \'name\': \'zhangsan\'}, {\'age\': 20, \'name\': \'zhangsan\'}]
[{\'age\': 10, \'name\': \'lisi\'}, {\'age\': 20, \'name\': \'zhangsan\'}]

希望本文所述对大家Python程序设计有所帮助。
