Fibonacci Sequence

A Fibonacci sequence is the integer sequence of 0, 1, 1, 2, 3, 5, 8....

The first two terms are 0 and 1. All other terms 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 term.

n = int(input("How many terms do you want? "))

## Initializing first two terms
n1 = 0
n2 = 1

count = 0

if n <= 0 :
    print('Please enter a positive number')
else:
    print("Fibonacci sequence:")
    while count < n:
        print(n1)
        nth = n1 + n2
        # update values
        n1 = n2
        n2 = nth
        count += 1

n = int(input("How many terms do you want? "))

## Initializing first two terms
n1 = 0
n2 = 1

count = 0

if n <= 0 :
    print('Please enter a positive number')
else:
    print("Fibonacci sequence:")
    while count < n:
        print(n1)
        n1, n2 = n2, n1+n2
        count += 1
