Python向方法中传递自定义类型参数

定义类型

class Fish:    def __init__(self,x):        self.num = xclass Turtle:    def __init__(self,y):        self.num = yclass Pool:    def __init__(self,x,y):        self.fish = Fish(x)        self.turtle = Turtle(y)    def print_num(self):        print(‘fish %d,trutle %d‘%(self.fish.num,self.turtle.num))#pool = Pool(10,1)#pool.print_num()

创建使用自定义类型的方法

import Animal as alfrom Animal import Fishdef PrintTest(X):    for colour in X:        print(colour)def PrintAnl(Fish):     print(Fish.num)

def PrintFish(fish=Fish):    print(fish.num)

调用

import PrintTest as ptimport  Animal as anlpt.PrintTest([‘1‘,‘2‘])fish = anl.Fish(5)pt.PrintAnl(fish)pt.PrintFish(fish)pool = anl.Pool(1,2)pool.print_num()拙见：向方法中传递自定类型参数时，格式：方法名(自定义类型,自定义类型) 或者 方法名(参数名=自定义类型,

参数名=自定义类型

)。传递内置类型时Python自动会判断类型
