#FIBONACCI PYTHON RECURSION HOW TO#

We have defined a recursive function which calls itself to calculate the next number in the sequence. The difference is in the approach we have used. The output from this code is the same as our earlier example. This loop calls the calculate_number() method to calculate the next number in the sequence. In other words, our loop will execute 9 times. This loop will execute a number of times equal to the value of terms_to_calculate. Let’s begin by setting a few initial values: This is why the approach is called iterative. Each time the while loop runs, our code iterates. This approach uses a “ while” loop which calculates the next number in the list until a particular condition is met. Let’s start by talking about the iterative approach to implementing the Fibonacci series. Python Fibonacci Sequence: Iterative Approach The rule for calculating the next number in the sequence is: It keeps going forever until you stop calculating new numbers. Each number is the product of the previous two numbers in the sequence. The Fibonacci Sequence is a series of numbers. We’ll look at two approaches you can use to implement the Fibonacci Sequence: iterative and recursive.
