Python实现斐波那契数列，,1、最普通的写法de

1、最普通的写法

def fibonaci(num):    a = 0    b = 1    print(a, end=" ")    for _ in range(num):        c = a + b        a = b        b = c        print(a, end=" ")fibonaci(10)

2、Python风格的写法

def fibonaci(num):    a = 0    b = 1    print(a, end=" ")    for _ in range(num):        a, b = b, a+b        print(a, end=" ")fibonaci(10)

3、Python的迭代器实现

class Fibonacci:    def __init__(self, max_num):        self.max_num = max_num        self.current_num = 0        self.first_num = 0        self.second_num = 1    def __iter__(self):        return self    def __next__(self):        if self.current_num < self.max_num:            result = self.first_num            self.first_num, self.second_num = self.second_num, self.first_num + self.second_num            self.current_num += 1            return result        else:            raise StopIteration# 创建斐波那契额对象f = Fibonacci(10)for i in f:    print(i, end=‘ ‘)
