python 初识面向对象

class Car:  #类名首字母大写,严格遵守驼峰命名规范
    pass

#造车
c = Car() #类名()  #创建对象
##出场之后进行改装
c.color = "红色"  #对象属性  . : 的  当属性不存在的时候相当于添加一个属性
c.pai = "冀F8888" #   对象属性
c.pailiang = "1.5T"

print(c.color)  #此车是红颜色
print(c.pai)
print(c.pailiang)

c.color = "绿颜色"  #当属性存在时候是修改属性信息

#对象.属性 = xxx  设置属性信息

print(c.color)

#相当于字典的改的操作

class Car:
    def __init__(self,color,pai,pailiang): init初始化方法.在创建对象的时候.
    self.color = color
    self.pai = pai
    self.pailiang = pailiang

#跑:动作,功能 -> 函数
#在类中写的函数 -> 方法
#self 当前类的对象
    def pao(self):
        print('%s是我的车,能跑' % self.color)

    def jump(self):
        print('哈哈 搞笑')

c2 = Car("蓝色",'冀F66666','1.8T')
print(c.color)
print(c2.color)
c.pao() #车c 跑
c2.jump()  #c2跳
