Today, We want to share with you **fibonacci series in python**.In this post we will show you **fibonacci series in python without recursion**, hear for *Fibonacci Series generates subsequent number by including two previous numbers.* we will give you demo and example for implement.In this post, we will learn about *GO Program To Display Fibonacci Sequence* with an example.

## Python Program to Print the Fibonacci sequence

Contents

each number is the sum of the two previous numbers. The first two numbers in the Fibonacci series are 0 and 1. Fibonacci series satisfies the following conditions β

Fn = Fn-1 + Fn-2

The beginning of the sequence is thus:

**0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, β¦β¦..**

### display the Fibonacci sequence up to n-th term

**Example 1: **

# Program to display the Fibonacci sequence up to n-th term nseries = int(input("How many series? ")) # first two series n1, n2 = 0, 1 count = 0 # check if the number of series is valid if nseries <= 0: print("Please enter a positive integer") elif nseries == 1: print("Fibonacci sequence upto",nseries,":") print(n1) else: print("Fibonacci sequence:") while count < nseries: print(n1) nth = n1 + n2 n1 = n2 n2 = nth count += 1

**Results**

How many series? 7 Fibonacci sequence: 0 1 1 2 3 5 8

### Python Fibonacci Series program Using While Loop

**Example 2: **

Number = int(input("\nPlease Enter the Range Number: ")) i = 0 First_Value = 0 Second_Value = 1 while(i < Number): if(i <= 1): Next = i else: Next = First_Value + Second_Value First_Value = Second_Value Second_Value = Next print(Next) i = i + 1

**Fibonacci Series program Using For Loop**

Number = int(input("\nPlease Enter the Range Number: ")) First_Value = 0 Second_Value = 1 for Num in range(0, Number): if(Num <= 1): Next = Num else: Next = First_Value + Second_Value First_Value = Second_Value Second_Value = Next print(Next)

### Python Fibonacci Series program Using Recursion

**Example 3: **

def ExampleOfFiboDemo_series(Number): if(Number == 0): return 0 elif(Number == 1): return 1 else: return (ExampleOfFiboDemo_series(Number - 2)+ ExampleOfFiboDemo_series(Number - 1)) Number = int(input("\nPlease Enter the Range Number: ")) for Num in range(0, Number): print(ExampleOfFiboDemo_series(Num))

## Sum of Fibonacci Numbers

**Examples :**

Input : n = 3 Output : 4 Explanation : 0 + 1 + 1 + 2 = 4 Input : n = 4 Output : 7 Explanation : 0 + 1 + 1 + 2 + 3 = 7

### Python 3 Program to find sum of Fibonacci numbers

def calculateSum(n) : if (n <= 0) : return 0 fibo =[0] * (n+1) fibo[1] = 1 # Initialize result sm = fibo[0] + fibo[1] # Add remaining series for i in range(2,n+1) : fibo[i] = fibo[i-1] + fibo[i-2] sm = sm + fibo[i] return sm # Driver program to test # above function n = 4 print("Sum of Fibonacci numbers is : " , calculateSum(n)) # This code is contributed # by Nikita tiwari.

I hope you get an idea about **fibonacci series in python using list**.
