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...

题外话:由于递归深度可控,一般写类似递归的方法时尽量使用迭代器,例如Fibonacci数列,在python高级中我会把迭代器实现Fibonacci数列的方法贴出来,而不是用递归。...递归深度尽量不去修改,用起来也会很绕。...下面我贴出来如何测试出本机递归深度: def func(num): if num == 1: return 1 else: return n...
Question 5: Insert the correct base case to stop the recursion in the sum_to_n function. def sum_to_n(n): if ___: return 0 return n + sum_to_n(n - 1) ▼ Question 6: What will the following recursive function output when fibonacci(4) is called? def ...
Python Fibonacci Series Using Recursion Here recursive function code is smaller and easy to understand. So using recursion, in this case, makes sense.What is the Base Case in Recursion? While defining a recursive function, there must be at least one base case for which we know the result. ...

As an example, consider computing the sequence of Fibonacci numbers, in which each number is the sum of the preceding two. def fib(n): if n == 0: return 0 if n == 1: return 1 else: return fib(n-2) + fib(n-1) Base case: What’s the simplest input I can give to fib? If...
