简介: 在Python中实现斐波那契数列(Fibonacci sequence)的4中方法 1. 递归方法 (简洁但效率低,尤其对于较大的n值) Python 1def fibonacci_recursive(n): 2 if n <= 0: 3 return "输入的数值应大于0" 4 elif n == 1: 5 return 0 6 elif n == 2: 7 return 1 8 else: 9 return fibonacci_...
Python实现 importsys#循环 返回第 n 个数defloop(n):first,second=0,1foriinrange(n):first,second=second,first+secondreturnfirst#循环,返回斐波那契数列deffib(n):v=[0,1]foriinrange(2,n+1):v.append(v[i-1]+v[i-2])returnv# return v[n]if__name__=='__main__':print(fib(int(sys....
第一个是使用队列的方式: 1deffibonacciSeq(num):2fibonacciSeqList =[]3foriinxrange(0, num):4iflen(fibonacciSeqList) < 2:5fibonacciSeqList.append(1)6continue7fibonacciSeqList.append(fibonacciSeqList[-1]+fibonacciSeqList[-2])8fibonacciSeqList.pop(0)9returnfibonacciSeqList[-1] 第二个同样使用...
2. 循环迭代法 (效率更高) Python 1def fibonacci_iterative(n): 2 if n <= 0: 3 return [] 4 elif n == 1: 5 return [0] 6 elif n == 2: 7 return [0, 1] 8 else: 9 fib_sequence = [0, 1] 10 for _ in range(2, n): 11 fib_sequence.append(fib_sequence[-1] + fib_se...
斐波那契数列(Fibonacci sequence),又称黄金分割数列、因意大利数学家列昂纳多·斐波那契(Leonardoda Fibonacci)以兔子繁殖为例子而引入,指的是这样一个数列:1、1、2、3、5、8、13、21、34。。。这个数列从第3项开始,每一项都等于前两项之和。 根据以上定义,用python定义一个函数,用于计算斐波那契数列中第n项的数字...

Python 斐波那契数列Python3 实例斐波那契数列指的是这样一个数列 0, 1, 1, 2, 3, 5, 8, 13,特别指出:第0项是0,第1项是第一个1。从第三项开始,每一项都等于前两项之和。 Python 实现斐波那契数列代码如下:实例(Python 3.0+) # -*- coding: UTF-8 -*- # Filename : test.py # author by : ...
Using Iteration and a Python Function The example in the previous sections implements a recursive solution that uses memoization as an optimization strategy. In this section, you’ll code a function that uses iteration. The code below implements an iterative version of your Fibonacci sequence algorith...
Now it may be possible to do some of these things in Python but that is some way off for me! Aug 21, 2023 Playing with the concept a bit more, it could be worth defining a generalised SCAN function that applies to both types of setup. For Fibonacci sequence, ...
