Python Fibonacci Series Sum Extension

Integrate the Fibonacci sum calculation feature into existing Python code to display series up to a term and compute its sum iteratively.

Prompt

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)
    
number_of_terms = 10
for i in range(number_of_terms):
    print(fibonacci(i))

Answer

Python Code Extension

To extend the existing code snippet to include a feature that calculates the sum of the Fibonacci series up to a certain term, you can integrate the following addition below the existing code.

def fibonacci_sum(n):
    sum_result = 0
    for i in range(n):
        sum_result += fibonacci(i)
    return sum_result

number_of_terms = 10
print("Fibonacci Series:")
for i in range(number_of_terms):
    print(fibonacci(i))

print("Sum of Fibonacci Series:")
print(fibonacci_sum(number_of_terms))

Summary of Changes

Added a new function fibonacci_sum that calculates the sum of Fibonacci series up to a given term.
Incorporated a loop to calculate the sum iteratively in the fibonacci_sum function.
Modified the existing code to display the Fibonacci series up to the specified number of terms.
Printed the sum of the Fibonacci series after displaying the series.

This extension maintains the original functionality while introducing the sum calculation as per the provided requirements.
