python(面向对象设计)
作者:互联网
三大编程范式
1.面向过程
2.面向对象
3.函数式编程
例.对象建立,但只是单一的
# -*- coding: utf-8 -*- people1={ 'name':'bob', 'age':'10', 'Gender':'man', 'sport':'basketball' } people2={ 'name':'lily', 'age':'12', 'Gender':'men', 'sport':'sing' } def do(people): print('%s like %s' % (people['name'],people['sport'])) def gender(people): print('%s is a %s' % (people['name'],people['Gender'])) do(people1) gender(people2)
进一步完善
# -*- coding: utf-8 -*-
def peoples(name,age,gender,sport): def do(people): print('%s like %s' % (people['name'],people['sport'])) def sex(people): print('%s is a %s' % (people['name'],people['gender'])) def init(name,age,gender,sport): people={ 'name':name, 'age':age, 'gender':gender, 'sport':sport, #行为 'do':do, 'sex':sex, } return people res=init(name,age,gender,sport) return res people1=peoples('bob','11','man','soccer') people1['do'](people1) people1['sex'](people1)
类:把一类事物的相同的特征和动作整合到一起,是一个抽象的概念。
对象:是基于类创建的一个具体的事物。是特征和动作整合到一起。
例子.创建学校类
特征:name,adder,type
动作:考试,招生,管理
简单版
# -*- coding: utf-8 -*- def school(name,addr,type): def exam(): print('------考试------') def enroll(): print('------招生------') def administration(): print('------管理------') sch={ 'name': name, 'addr':addr, 'type':type, 'exam': exam, 'enroll': enroll, 'administration': administration } return sch school1=school('实验','光明路','公立') school1['exam']() school1['enroll']() school1['administration']()
进一步加工
# -*- coding: utf-8 -*- def school(name,addr,type): def exam(): print('------考试------') def enroll(): print('------招生------') def administration(): print('------管理------') def intial(name,addr,type): sch={ 'name': name, 'addr':addr, 'type':type, 'exam': exam, 'enroll': enroll, 'administration': administration } return sch return intial(name,addr,type) school1=school('实验','光明路','公立') print(school1) school1['exam']() school1['enroll']() school1['administration']()
面向对象设计:用面向对象独有的语法class去实现
