Fibonacci Series Program in Python

In this post, you will learn how to write Fibonacci series of program using Python.

The Fibonacci series are the sequence of number in which the next number is the sum of the previous two numbers. Fibonacci series was known hundreds of years before. The "Fibonacci" name came from the nickname "Bonacci".

We can easily remember Fibonacci Sequence using the Fibonacci Day, which is November 23rd. As 23rd November has the digits "1, 1, 2, 3" which is part of the sequence.



In the above image, the first two numbers are 0 and 1. So, according to the Fibonacci rule the third number is 1 (sum of 0 and 1). The fourth number is 2 and so on.

0 + 1 = 1 // 0, 1, 1

1 + 1 = 2 // 0, 1, 1, 2

1 + 2 = 3 // 0, 1, 1, 2, 3

2 + 3 = 5 // 0, 1, 1, 2, 3, 5
0 ,1 , 1, 2, 3, 5, 8, 13, 21, 34....




series = int(input("How many number of series? "))
x1, x2 = 0, 1
count = 0

if series <= 0:
   ("Invalid: Please enter a positive integer")
elif series == 1:
   print("Fibonacci series upto ",series,":")
   print(x1)
else:
   print("Fibonacci series sequence:")
   while count < series:
       print(x1)
       xth = x1 + x2
       x1 = x2
       x2 = xth
       count += 1

Output of the above code

How many number of series? 30
