"Fibonacci Series"

The PROGRAM or TUTORIAL  is about a "Fibonacci Series"

Fibonacci Series - The Fibonacci sequence is a set of numbers that starts with a one or a zero, followed by a one, and proceeds based on the rule that each number (called a Fibonacci number) is equal to the sum of the preceding two numbers. ... F (0) = 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ...

SOLUTION:

# Fibonacci Series

# 0 1 1 2 3 5 8 13
def fibonacci(n):
    if n == 1:
        return 0
    elif n == 2:
        return 1
    else:
        return fibonacci(n - 1) + fibonacci(n - 2)
number1 = int(input("Enter then number\n"))
print(fibonacci(number1))
