![]() #decreasing the length by two because the first 2 Fibonacci numbers Iterative Python Code for printing Fibonacci Sequence: def PrintFibonacci(length): So the final Fibonacci sequence for length 7 will be. And second will point to the next Fibonacci number that we calculatod above. Print (first + second) = Now variable first will point to variable second. And second will point to the next Fibonacci number that we calculated above. Then the flow of the algorithm will be like this: Iterations Once the loop terminates, terminate the programĬonsider that we need to print a Fibonacci sequence of length 7.Decrement the length variable and repeat from step 3.Update first and second variable (first will point to the second, and the second will point to first + second).Loop (length is less than series length).Create another variable to keep track of the length of the Fibonacci sequence to be printed (length).Create 2 variables and initialize them with 0 and 1 (first = 0, second = 1).Here's an iterative algorithm for printing the Fibonacci sequence: Recursion, on the other hand, means performing a single task and proceeding to the next for performing the remaining task. Iteration means repeating the work until the specified condition is met. You can write a computer program for printing the Fibonacci sequence in 2 different ways: How to Print the Fibonacci Sequence in Python Leonardo was known as one of the most talented mathematicians of the middle ages. He was from the Republic of Pisa, which is why he is also known as Leonardo of Pisa. This fascinating sequence is widely associated with the mathematician Leonardo Pisano, also known as Fibonacci. ![]() We can use this sequence to find any nth Fibonacci number. Mathematically, the Fibonacci Sequence is represented by this formula: Within this continuous sequence, every individual number is a Fibonacci number. Here's a diagram showing the first 10 Fibonacci numbers: Similarly, the next Fibonacci number is - 0, 1, 1, (2). We can represent this more mathematically like 0, 1, (1). Then, to find the next number, you add the last number you have and the number before it. They're the first two numbers in the sequence. Then every following number is made up of adding the previous two numbers together.įor example, take 0 and 1. The Fibonacci sequence starts with two numbers, that is 0 and 1. And adding the previous 2 numbers some number of times forms a series that we call the Fibonacci Series. The Fibonacci Sequence is a sequence of numbers in which a given number is the result of adding the 2 numbers that come before it. In this article, I'll explain a step-by-step approach on how to print the Fibonacci sequence using two different techniques, iteration and recursion.īefore we begin, let's first understand some basic terminology. Questions about the Fibonacci Series are some of the most commonly asked in Python interviews.
