# -*- 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:

希望本文所述对大家Python程序设计有所帮助。
