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
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 −
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, ……..
display the Fibonacci sequence up to n-th term
# 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
How many series? 7 Fibonacci sequence: 0 1 1 2 3 5 8
Python Fibonacci Series program Using While Loop
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
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
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 = * (n+1) fibo = 1 # Initialize result sm = fibo + fibo # 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.
