Python Program to Print Fibonacci Sequence

 In this program, we will see how to Print Fibonacci Sequence.

Fibonacci Sequence is the sum of the two numbers that precede it.

# 0 1 1 2 3 5 8 13 21........

In this program, we are using if, elif, else conditions & a for loop.

Follow the code given below:

def fib(n):

    a=0

    b=1

    if n<=0:

        print('Incorrect input!')

    elif n==1:

        print(a)

    else:

        print(a)

        print(b)

        for i in range(2,n):

            c=a+b

            a=b

            b=c

            print(c)

fib(int(input("Enter how many fibonacci numbers needed = ")))

-----------------

Output:

Enter how many Fibonacci numbers needed = 5

0 1 1 2 3

Enter how many Fibonacci numbers needed = 8

0 1 1 2 3 5 8 13

That's it!
