# -*- encoding: UTF-8 -*-class Student: name = '' age = 0 def __init__(self, name, age): self.name = name self.age = agedef convert_to_dict(obj): '''把Object对象转换成Dict对象''' dict = {} dict.update(obj.__dict__) return dictdef 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_arrdef 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 dictstu = 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。
