原因如@chenaixu所说。代替方案1：operator.lt(a, b) 小于operator.le(a, b) 小于等于operator.eq(a, b) 等于operator.ne(a, b) 不等于operator.ge(a, b) 大于等于operator.gt(a, b) 大于代替方案2：(a-b)>(b-a)等效于cmp(a,b)

move(3,'A','B','C') move(n,a,b,c) #第一次调用 传值'A','B','C' 此时n=3,a='A',b='B',c='C'这几个值在本次调用中都不变 #if(n == 1) n=3不走 move(n-1,a,c,b) #调用主函数，传值n=2,a='A',c='C',b='B'，将值传入，注意传入的是值，将2,'A','C','B'按位置传下去，也就是move(2,'A','C','B') move(n,a,b,c) #此处进入第一层循环 ...
