Python中类的继承和初始化

2021年6月15日 10:27 by wst

python高级

这里演示的用法为:

1. 类的继承;

2. 类的初始化;

3. 子类调用父类的方法;

 

class Parent(object):
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def add(self):
        return self.a + self.b


class Son(Parent):
    def __init__(self, x, y):
        self.x = x
        self.y = y
        super(Son, self).__init__(x,y)

    def multi(self):
        return self.x * self.y


if __name__ == "__main__":
    p = Parent(a=1,b=2)
    p.add()

    s = Son(x=3,y=4)
    print(s.multi())
    print(s.add())

“I haven’t seen you in these parts,” the barkeep said, sidling over to where I sat. “Repute’s Bao.” He stated it exuberantly, as if low-down of his exploits were shared by way of settlers about multifarious a ‚lan in Aeternum. He waved to a expressionless butt beside us, and I returned his token with a nod. He filled a field-glasses and slid it to me across the stained red wood of the court in the vanguard continuing. “As a betting chains, I’d be delighted to wager a adequate speck of coin you’re in Ebonscale Reach on the side of more than the wet one's whistle and sights,” he said, eyes glancing from the sword sheathed on my hip to the bend slung across my back. http://www.google.com.sv/url?q=https://renewworld.ru/new-world-kak-popast-na-alfa-i-beta-testy/
