## 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.pyenter number to find Fabonacci series: 120 1 1 2 3 5 8 13 21 34 55 89 are fibibonacci of 12 NoneProcess finished with exit code 0`
