Recursive calls in python

WebbFirstly, let’s implement the Fibonacci function using a recursive function. def fib_recursion (n): if n == 0: return 0 elif n == 1: return 1 else: return fib_recursion (n-1) + fib_recursion (n-2) We can verify the function by output the 20th number of the Fibonacci sequence. Webb17 sep. 2024 · The repeated recursive calls produce repetitions. When the function makes a recursive call, the first argument n–the number of disks–reduces by one. The repetition ends when n = 1, and the function does not make any further recursive calls. We have a taste of recursion.
