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. WebbSo how can we achieve the following in python? class mine: def inclass (self): self = mine (); def recur (num): print (num, end="") if num > 1: print (" * ",end="") return num * self.recur …
