How to Create a Fibonacci Sequence in Python

Submitted by razormist on Thursday, January 4, 2024 - 23:32.

In this tutorial, we will create a "How to Create a Fibonacci Sequence in Python". The purpose of this tutorial is to teach you how to generate a Fibonacci sequence in Python. We will delve deep into the process of generating Fibonacci numbers. I will provide a sample program to demonstrate the actual coding of this tutorial.

This tutorial is simple and easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program will give you an accurate result after you provide a term for your sequence. I will do my best to provide you with the most simplified method of creating this program, called "Fibonacci Sequence". So, let's start with the coding.

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 the Fibonacci Sequence program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
   print("\n\n========== How to Create a Fibonacci Sequence ==========")
   
   ret=False
   nterms = int(input("How many terms? "))
 
   n1, n2 = 0, 1
   count = 0
 
   if nterms <= 0:
      print("Please enter a positive integer")
   elif nterms == 1:
      print("Fibonacci sequence upto",nterms,":")
      print(n1)
   else:
      print("Fibonacci sequence:")
      while count < nterms:
          print(n1)
          nth = n1 + n2
          n1 = n2
          n2 = nth
          count += 1
 
 
 
   user_input=input("\n\nTry again? (Yes/No): ")
   print("\n\n")
   if user_input.lower()=='no':
      print("Exit program.")
      break
 
   elif user_input.lower()=='yes':
      ret=True
 
   else:
      print("Wrong input.")
      ret=True
 
 
   if ret:
      continue    

In the provided code, we proceeded to enclose the entire code with a while loop. Next, we set a variable that will take the input value of a term. Following that, we use a conditional statement to check if the number is positive. Then, we use a while loop to increment the sequence for our Fibonacci number.
