Python は、動的データ型を備えた解釈型のオブジェクト指向の高水準プログラミング言語です。この記事では、Python クラスの継承の例を示します。
コード例は次のとおりです:
#! /usr/bin/python
# Filename: inherit.py
# Author: yanggang
class SchoolMember:
def __init__(self,name,age):
self.name = name
self.age = age
print 'init SchoolMember: ', self.name
def tell(self):
print 'name:%s; age:%s' % (self.name, self.age)
class Teacher(SchoolMember):
def __init__(self,name,age,salary):
SchoolMember.__init__(self,name,age)
self.salary = salary
print 'init Teacher: ', self.name
def tell(self):
SchoolMember.tell(self)
print 'salary: ', self.salary
class Student(SchoolMember):
def __init__(self,name,age,marks):
SchoolMember.__init__(self,name,age)
self.marks = marks
print 'init Student: ', self.name
def tell(self):
SchoolMember.tell(self)
print 'marks: ', self.marks
t = Teacher('yanggang', 20, 1000)
s = Student('liming', 12, 86)
members = [t,s]
print
for member in members:
member.tell() 実行結果:
[work@db-testing.baidu.com python]$ python inherit.py init SchoolMember: yanggang init Teacher: yanggang init SchoolMember: liming init Student: liming name:yanggang; age:20 salary: 1000 name:liming; age:12 marks: 86
