fibonacci using recursion

Which code is better to print Fibonacci series?
As you’ve discovered, there is always more than one way to solve the same problem. There are two measures of success as a beginner: Does it work? Is it understandable. If they both work, pick the one that is easier for you to understand. More on reddit.com

Nth Fibonacci number recursive method only works for small integers? (Java)
it doesn't work for any number above around 80-90 (Approximation) The 80th fibonacci number is 14,472,334,024,676,221. That's about 14 quadrillion. Note that your fibonacci function only does two things: it can either return 1, or it can add two previous results together. This means that fib(1) or fib(2) must be called exactly 14,472,334,024,676,221 times (and all the other calls are just aggregating these lesser terms). So it "runs indefinitely" because it needs to crunch through a dozen quadrillion calls. Use an iterative approach instead, or cache previously computed values. More on reddit.com

r/learnpython on Reddit: fibonacci using recursion
January 14, 2023 -

I'm working on the fibonacci exercise but my code doesn't seem to be right, if I run it on pythontutor the page says it is probably an infinite loop.

this is the problem:

The Fibonacci sequence is one of the most famous formulas in mathematics. Each number in the sequence is the sum of the two numbers that precede it. For example, here is the Fibonacci sequence for 10 numbers, starting from 0: 0,1,1,2,3,5,8,13,21,34.

Write a program to take N (variable num in code template) positive numbers as input, and recursively calculate and output the first N numbers of the Fibonacci sequence (starting from 0).

Sample Input 6

Sample Output 0 1 1 2 3 5

If you are making the Fibonacci sequence for n numbers, you should use n<=1 condition as the base case.

this is my code so far:

num = int(input())
def fibonacci(n):
       if(n <=1):
           return n
       else:
           return (fibonacci(n-1) + fibonacci(n-2))


fibonacci(num)

November 27, 2024 - In this case 0 and 1. So, we get 0+1=1. Hence 1 is printed as the third term. The next term is generated by using the second and third term and not using the first term. It is done until the number of terms you want or requested by the user. In the above example, we have used five terms. Next, let’s write a Python program to implement it.
