python 循环为循环的类，它递归调用一个函数直到满足条件，然后移动到下一个函数并调用

class Ringloop (object):
	
#"A class that loops as a ring, it recursively calls function one until a condition is True, then recursively calls function two until the second condition is True. The loop keeps iterating in a ring across the two functions until the end condition is satisfied, and the final value is returned."

		self.f1 = f1 #first function

		self.c1 = c1 #condition for checkpoint1
		self.c2 = c2 #condition for checkpoint2
		self.end = end #condition to return the value
	def checkpoint1(self):
