Prompt

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)
    
print(fibonacci(10))

Answer

Code Documentation

def fibonacci(n):
    """
    Calculate the nth Fibonacci number recursively.

    Parameters:
    n (int): The index of the Fibonacci number to calculate.

    Returns:
    int: The nth Fibonacci number.

    Raises:
    - This function does not raise any exceptions.

    Notes:
    - The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones.
    - The first two numbers in the sequence are 0 and 1.
    - This implementation uses recursion to calculate the Fibonacci number at index n.
    """

    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

# Example usage
print(fibonacci(10))
