TypeError: unsupported operand type(s) for &: ‘list‘ and ‘list‘

我的报错

	Traceback (most recent call last):
  File "poc.py", line 34, in <module>
    if(result_lens[0] == result_lens[2] & result_lens[0] != result_lens[1]):
TypeError: unsupported operand type(s) for &: 'list' and 'list'

解决：输出result_lens的内容

出错的原因：result_lens列表的内容不是数字–》排查修改代码
