python3学习笔记--003--写一个自定义的包

代码布局：

mypackage/human.py

#!/usr/bin/env python
class person:
    def __init__(self,name,age,sex):
        self.name = name
        self.age = age
        self.sex = sex

    def sayHello(self,msg=‘Hello‘):
        print(msg)

    def printInfo(self):
        print(‘name:‘ + self.name + ‘ age:‘ + str(self.age) + ‘ sex:‘ + self.sex )

mypackage/student.py

#!/usr/bin/env python
from mypackage.human import person

class student(person):
    def __init__(self,name,age,sex,stuid,score):
        person.__init__(self,name,age,sex)
        self.stuid = stuid
        self.score = score

    def sayHi(self,msg=‘Hi‘):
        print(msg)

    def printInfo(self):
        person.printInfo(self)
        print(‘stuid:‘ + str(self.stuid) + ‘ score:‘ + str(self.score) )

test.py

#!/usr/bin/env python
from mypackage.human import person
from mypackage.student import student

per = person(‘person‘,24,‘man‘)
per.sayHello()
per.printInfo()

stu = student(‘xiaodaima‘,23,‘man‘,1001,100)
stu.sayHi()
stu.printInfo()

运行效果：

[[email protected] packagetest]$ ./test.py
Hello
name:person age:24 sex:man
Hi
name:xiaodaima age:23 sex:man
stuid:1001 score:100
[[email protected] packagetest]$

自定义的包中，必须有__init__.py文件

在自定义包的时候，如果要引入其它包，则使用from import就可以，使用import怎么在自定义包中再引入其它的自定义包，暂时还不知道具体方法
