Python Fibonacci Series with Example

Fibonacci Series Program in Python

In this program, we will learn to find the Fibonacci series program in python using the user-defined function. Before to start this you have to know about this:

for loop

if and else if statement

Fibonacci series is the sequence of 0, 1, 1, 2, 3, 5, 8,……

The first two values are 0 and 1. All other values are obtained by adding the preceding two terms. This means to say the nth term is the sum of (n-1)th and (n-2)th terms.

Fibonacci Series Source Code

def fibonacci_ser(num):

a=0

b=1

if num == 1:

print(a)

elif num == 2 :

print(a, b)

else:

print(a,b,end=" ")

for i in range(num-2):

c=a+b

a=b

b=c

print(b,end=" ")

num1=int(input("enter number to find Fabonacci series: "))

print(f'are fibibonacci of {num1}',fibonacci_ser(num1))

Output:

C:\Users\Pramod\PycharmProjects\pythonProject\venv\Scripts\python.exe C:/Users/Pramod/PycharmProjects/pythonProject/main.py
enter number to find Fabonacci series: 12
0 1 1 2 3 5 8 13 21 34 55 89 are fibibonacci of 12 None

Process finished with exit code 0
