可以把实例对象用类似函数的形式表示，进一步模糊了函数和对象之间的概念


class Fib(object):
  def __init__(self):
    pass
  def __call__(self,num):
    a,b = 0,1;
    self.l=[]
    
    for i in range (num):
      self.l.append(a)
      a,b= b,a+b
    return self.l
  def __str__(self):
    return str(self.l)
  __rept__=__str__
      
f = Fib()
print f(10)


以上这篇对python特殊函数 __call__()的使用详解就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
