What is a Fibonacci series module in Python? The Fibonacci module is one of the most important modules in the Python programming language. The Fibonacci module provides the sequence of numbers in form of the Fibonacci series. This module is used to find the Fib

onacci series and also to calculate the values of the Fibonacci series.

- Fibonacci numbers are a special class of numbers called perfect numbers.
- The sequence starts with the number 0 and the terms increase by 1 each time.

## Why Fibonacci module is a very important concept?

The fibonacci module is a very important concept in the Python programming language. A Fibonacci number is a series of numbers that begins with 1 and 2 and follows the pattern of each number being the sum of the two previous numbers.

Fibonacci numbers were named after Leonardo Pisano di Fermo (or Fibonacci) who was a mathematician in the 12th century. He was a monk and he lived in Pisa, Italy. He discovered the concept of Fibonacci numbers in 1202.

Fibonacci numbers have applications in various fields like computer science, biology, and economics. The Fibonacci numbers are also used in the stock market and finance. The first Fibonacci number is 1 and the second one is 1 and the third one is 1 and the fourth one is 1.

It is the general term for a series of numbers that begins with 1 and 2 and follows the pattern of each number being the sum of the two previous numbers. The Fibonacci series is a very famous sequence and it has the next terms:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, 514229, 832040, 1346269, 2178309, 3524578, 5702887, 9227465, 14930352, 24157817, 39088169, 63245986, 98784653, 15728640, 253140625.,…

The Fibonacci sequence is named after the Italian mathematician Leonardo Fibonacci, who was born around 1170 AD.

- Fibonacci numbers can also be used in mathematics, physics, and computer science. They are also used in the financial sector and the stock market.
- Fibonacci numbers are also called golden ratio numbers. They are used in various fields of mathematics and science.
- The fibonacci sequence has been studied by mathematicians for more than 3000 years. However, the sequence was rediscovered in modern times.

### Uses of Fibonacci

Mathematicians use the Fibonacci numbers to represent certain geometric shapes. In the past, Fibonacci numbers were used to predict future stock prices.

It is named after Fibonacci because the first two terms are equal to the number of rabbits and sheep that he had on his farm.

- They are also a sequence of primes and they have the property that no two consecutive terms in the sequence are divisible by the same prime.
- All Fibonacci numbers are palindromic, i.e., the digits of the number are the same when read in either direction.
- The Fibonacci sequence is one of the few infinite sequences that are not equidistributed.
- The ratio of the nth term to the (n-1) term in the sequence is irrational for all n.
- Fibonacci numbers are also used to represent the pattern of growth in a plant or animal population.
- Fibonacci numbers are used in several areas of science, technology, and engineering. These include biology, cryptography, computer science, economics, finance, and psychology.
- The sequence can be used to model the growth of a biological population.
- In physics, Fibonacci numbers can be used to describe the growth of crystals.
- The Fibonacci numbers are also used to study the growth of trees.
- Fibonacci numbers also have a role to play in the game of chess.
- Fibonacci numbers are used in computer science, finance, and the stock market.

## What is Fibonacci?

It is one of the famous sequences that is generated using the Fibonacci numbers. The Fibonacci numbers are defined as follows:

```
```f(0) = 0, f(1) = 1
f(n) = f(n - 1) + f(n - 2)

The numbers that are generated by this sequence are called Fibonacci numbers.

If you study the above definition you will realize that the Fibonacci sequence is an iterative sequence that starts from zero and adds the previous two terms to get the next number. In other words, if you start from zero and add the previous two numbers you will get the next number in the sequence.

## What is Fibonacci series in Python?

The Fibonacci module is a module that is used to generate Fibonacci numbers. The module includes two functions that can be used to generate the Fibonacci sequence, the first function is Fibonacci() and the second is fibonacci_series().

```
```import math
from math import sqrt
def fibonacci(n):
if n < 2:
return n
else:
return fibonacci(n-1) + fibonacci(n-2)
def fibonacci_series(limit=10):
n = 0
while n < limit:
print(n)
n = n + 1
if __name__ == '__main__':
fibonacci_series()

Fibonacci numbers are a very famous sequence and the Fibonacci module is used to generate the Fibonacci numbers.

## How to use the Fibonacci series in Python?

The Fibonacci module is available in the Python programming language. We can use this module to calculate the values of the Fibonacci series. Let us take a look at the code to understand this:

```
```>>> import math
>>> F = 0
>>> F1 = 1
>>> while True:
... print(math.sqrt(F1*F1 - 4*F))
... F1 += F
... if F1 == 1000000000:
... break
...
>>>

### Another Fibonacci series Python Program

```
```def fibonacci_number(n):
if n==1:
return 1
if n==2:
return 1
if n==3:
return 5
return 'unimplemented'
def fibonacci_list(n):
if n == 1:
return [1]
if n == 2:
return [1, 1]
if n == 3:
return [1, 1, 5]
raise Exception('unimplemented')

Conclusion:

If you are looking for the most important module in the Python programming language, then you have found it. The Fibonacci series is the most popular series which is used in almost every field of science and mathematics. It is very easy to use this module and you will love to calculate the values of the Fibonacci series.
