找到问题了，个位数的不用做处理的，只需添加个判断就行了

修改后的代码： import math

def _fn_num(): n=1 while True: yield n n=n+1

def _fn_filter(n): i=0 ls=str(n) L=len(ls) if L == 1: return True while i <= math.ceil(L/2): if ls[i] != ls[-(i+1)]: return False else: i=i+1 return True

def is_palindrome(): numList=_fn_num() while True: n = next(numList) yield next(filter(_fn_filter,numList))

def show(): ind = 1
for x in is_palindrome(): ind=ind+1 print(x) if ind > 10: break show()
