How to Find the Sum of Fractional Sequence in Python

In this tutorial, we will write an example to print Fractional Sequence with a loop and calculate the sum of the series.

Source Code

#! /usr/bin/env python3
# -*- coding: utf-8 -*-
a = 2.0
b = 1.0
sum = 0
for n in range(1,21):
    sum += a / b
    t = a
    a = a + b
    b = t
print('The sum of fractional sequence: %s'%sum)

Output:

The sum of fractional sequence: 32.66026079864164
