day⑥:面向对象

一.类初识-cs_game

#!/usr/bin/env python
#coding=utf-8
class Role(object): #新式类的写法
    ac=None
    def __init__(self,name,role,weapon,life_value=100,money=15000):
        self.name=name
        self.role=role
        self.weapon=weapon
        self.life_value=life_value
        self.money=money
    def shot(self):
        print("shooting...")
    def got_shot(self):
        print("ah....,I got shot...")
    def buy_gun(self,gun_name):
        print("just bought %s"%gun_name)
        self.weapon=gun_name
#实例化
t1=Role("yaobin","boy","AK47")  #此时self相当于t1，Role(t1,"yaobin","boy","AK47")
t2=Role("test","girl","B22")    #此时self相当于t1，Role(t1,"test","girl","B22")
t3=Role("test2","girl","B23")
t4=Role("test3","girl","B24")
#执行方法
#t1.buy_gun("new1") #相当于Role.buy_gun(t1,"new1")
#t2.buy_gun("new2")  #相当于Role.buy_gun(t2,"new2")
#print(t1.weapon)
#print(t2.weapon)
t1.ac="China Brand"  #实例改属性
t2.ac="US Brand"     #实例改属性
Role.ac="Janpanese Brand"  #改类属性
print("t1:",t1.weapon,t1.ac)
print("t2:",t2.weapon,t2.ac)
print("t3:",t3.weapon,t3.ac)
print("t4:",t4.weapon,t4.ac)
# print(Role.buy_gun)

#结果：
t1: AK47 China Brand
t2: B22 US Brand
t3: B23 Janpanese Brand
t4: B24 Janpanese Brand

二.继承_school_class

#!/usr/bin/env python
#coding=utf-8
class SchoolMember(object):
    members=0
    def __init__(self,name,age,sex):
        self.name=name
        self.age=age
        self.sex=sex
        self.enroll()
    def tell(self):
        print("my name is %s"  %self.name)
    def enroll(self):
        SchoolMember.members+=1
        print("33[32;1mnew member [%s] is enrolled,now there are [%s] members.33[0m"%(self.name,SchoolMember.members) )
    #def __del__(self):
    #    print("33[31;1mmember [%s] is dead!33[0m" %self.name)
class Teacher(SchoolMember):
    def __init__(self,name,age,sex,course,salary):
        super(Teacher,self).__init__(name,age,sex)
        #SchoolMember.__init__(self,name,age,sex) #经典类的写法，旧，不要用
        self.course=course
        self.salary=salary
    def teaching(self):
        print("Teacher [%s] is teaching [%s] for class [%s]"%(self.name,self.course,"s12"))
class Student(SchoolMember):
    def __init__(self,name,age,sex,course,tuition):
        super(Student,self).__init__(name,age,sex)
        self.course=course
        self.tuition=tuition
    def pay_tution(self):
        print("cao ,student [%s] paying tution" %self.tuition)
s1=Student("yaobin",24,"boy","py","1800")
t1=Teacher("alex",30,"boy","py","100000")
s2=Student("meimei",25,"girl","py","1800")
t2=Teacher("wusir",27,"boy","py","120000")
s1.tell()
s1.pay_tution()
t1.tell()
t1.teaching()

#结果：
new member [yaobin] is enrolled,now there are [1] members.
new member [alex] is enrolled,now there are [2] members.
new member [meimei] is enrolled,now there are [3] members.
new member [wusir] is enrolled,now there are [4] members.
my name is yaobin
cao ,student [1800] paying tution
my name is alex
Teacher [alex] is teaching [py] for class [s12]
