斐波那契數列，簡單地說，起始兩項為0和1，此後的項分別為它的前兩項之後。

方式1：

def fibo(num):
    numList = [0,1]

    for i in range(num - 2):
        numList.append(numList[-2] + numList[-1])
    print ("前%d項斐波拉切數列為："  %num, numList)

if __name__=='__main__':
    fibo(10)

方式2：迭代器實現

class Fibs:
    def __init__(self, n=10):
        self.a = 0
 

        self.b = 1
        self.n = n
    def __iter__(self):
        return self
    def __next__(self):
        self.a, self.b = self.b, self.a + self.b
        if self.a > self.n:
            raise StopIteration
        return self.a

fibo = Fibs(100)
for each in fibo:
    print(each)
