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_...
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...
n=40# 计算前40项fibonacci_sequence=fibonacci(n)# 调用Fibonacci函数 1. 2. 步骤3 - 打印输出Fibonacci数列 我们将把计算得到的前40项Fibonacci数列打印出来,以便查看结果。 print(f"The first{n}Fibonacci numbers are:")# 提示输出fornuminfibonacci_sequence:print(num,end=" ")# 打印每个Fibonacci数字print...
使用Python实现斐波那契数列(Fibonacci sequence) 斐波那契数列形如 1,1,2,3,5,8,13,等等。也就是说,下一个值是序列中前两个值之和。写一个函数,给定N,返回第N个斐波那契数字。例如,1返回1 6返回8 我选择了两种方法,一种是将list变成一个队列,另一个则是使用环形队列。不多说,直接上代码;后面我会对为什...
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...

python3:斐波那契生成器未按预期工作 、 我知道与相比,下面是斐波那契生成器的次优实现,但我似乎不能理解为什么它不能像预期的那样工作: fl, fp = 1, 1 store = fl + fp fl = store print(next(fibonacci_sequence生成器的状态不是在每次迭代时根据yield关键字进行更新吗?
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...
