How to Find the Fibonacci Series Using Recursion in Python
In this tutorial, we will learn how to program "How to Find the Fibonacci Series Using Recursion in Python." The objective is to determine the Fibonacci series by applying a recursive approach. This tutorial will walk you through the step-by-step implementation of the Fibonacci function, helping you understand how recursion can be used to generate the series efficiently. By the end of this tutorial, you will have a clear understanding of how to apply recursion to solve this classic problem and how to integrate such recursive logic effectively into your Python programs.
This topic is straightforward to understand. Just follow the instructions provided, and you will be able to complete it with ease. The program demonstrated will show you the correct and efficient way to find the Fibonacci series. So, let’s dive into the coding process!
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- def fibonacci(n):
- if(n <= 1):
- return n
- else:
- return(fibonacci(n-1) + fibonacci(n-2))
- while True:
- print("\n============== Find the Fibonacci Series Using Recursion ==============\n")
- n = int(input("Enter number of terms:"))
- print("Fibonacci sequence:")
- for i in range(n):
- print(fibonacci(i))
- opt = input("\nDo you want to try again?(yes/no): ")
- if opt.lower() == 'yes':
- ret=False
- elif opt.lower() == 'no':
- ret=True
- print("Exiting program....")
- else:
- print("Please enter yes/no:")
- break
- if ret == False:
- continue
This Python program generates and prints the Fibonacci series using recursion. The fibonacci(n) function recursively calculates the n-th Fibonacci number. The user is prompted to enter the number of terms to display, and the program prints the sequence up to that number. It then asks if the user wants to try again and repeats or exits based on the input.
Output:
There you have it we successfully created How to Find the Fibonacci Series Using Recursion in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
