[py]python多继承

多继承执行顺序

调用父类2种方法:

class Fu:
def __init__(self):
print("fu init")
self.ty="mao"

class Zi(Fu):
def __init__(self):
# 方法1 不推荐
# super(Zi, self).__init__()
# 方法2: 推荐
Fu.__init__(self)
print("zi init")

z = Zi()

多继承查找执行过程

class A:
def bar(self):
print("bar")
self.f1()

class B(A):
def f1(self):
print("b")

class C:
def f1(self):
print("c")

class D(C,B):
pass

a = D()
a.bar()

socketserver模块执行过程案例:

import socketserver

r = socketserver.ThreadingTCPServer()
r.serve_forever()
