python类基本用法

#!/usr/bin/python3

class python_class:
    name = ''
    age = 0
    def __init__(self,name='roverq',age=18):
        self.name = name
        self.age = age
        print("name :" + self.name + ", age :" + str(self.age))

    def getName(self):
        print("name: " + self.name)
        return self.name

    def getAge(self):
        print("age: " + str(self.age))
        return self.age

if __name__ == "__main__":
    demo1 = python_class()
    name = demo1.getName()
    print(name)
    age = demo1.getAge()
    print(age)

    demo2 = python_class('test',13)
    demo3 = python_class(age = 15, name = 're')
