斐波那契数列(Fibonacci sequence),又称黄金分割数列、因数学家列昂纳多·斐波那契(Leonardoda Fibonacci)以兔子繁殖为例子而引入,故又称为“兔子数列”,指的是这样一个数列:1、1、2、3、5、8、13、21、34、……在数学上,斐波那契数列以如下被以递推的方法定义:F(1)=1,F(2)=1, F(n)=F(n-1)+F(n-2)(n>=3,n∈N*)
代码如下:
def fibonacci(n): i,n1,n2 = 0,1,1 while i < n: yield n1 n1,n2 = n2,n1+n2 i+=1 res = fibonacci(50) fi = [i for i in res] print(fi)
结果如下:
[1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, 514229, 832040, 1346269, 2178309, 3524578, 5702887, 9227465, 14930352, 24157817, 39088169, 63245986, 102334155, 165580141, 267914296, 433494437, 701408733, 1134903170, 1836311903, 2971215073, 4807526976, 7778742049, 12586269025]
