**Introduction:**

In mathematics, the Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1. The sequence goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. In this tutorial, we will learn how to print the Fibonacci series in Python using a while loop.

**What is a Fibonacci Series?**

A Fibonacci series is a sequence of numbers in which each number is the sum of the two preceding ones. The series starts with 0 and 1, and the next number in the sequence is the sum of the previous two numbers. The sequence goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. This sequence is named after the Italian mathematician Leonardo Fibonacci, who introduced it to the western world.

**Printing Fibonacci Series Using a While Loop**

a = 0

b = 1

while b <= 55:

print(b)

a, b = b, a + b

print(“Done”)

**Explanation of the Code:**

The program first initializes the variables `a`

and `b`

to 0 and 1, respectively. The `while`

loop is then used to iterate through the sequence until the value of `b`

reaches 55 or greater.

Inside the loop, the program prints the current value of `b`

which is the current term in the Fibonacci sequence. It then updates the values of `a`

and `b`

such that `a`

is assigned the current value of `b`

, and `b`

is assigned the sum of the previous values of `a`

and `b`

.

Once `b`

reaches 55 or greater, the program exits the loop and prints the message “Done”.
