在15秒循环后,我在下面的脚本中得到以下KeyError,完美地工作了10个小时.为什么一个关键错误只会在每15秒运行10个小时后出现一次？

错误:

Traceback (most recent call last):

  File "C:\venderFix.py", line 33, in <module>

    if j['results']:

KeyError: 'results'

码:

A = Arduino('COM3') #This will need to be COM3               
A.output([12]) #Output on pin 12

这个Python脚本可以运行好几天然后崩溃,你知道为什么会发生这种情况或如何调试它吗？它连接到一个Arduino,当它通过串行接收'1'时发送一个高电平引脚.该脚本在计算机启动时启动,应该永久运行.如果它确实崩溃了,我没有办法重新启动脚本,因为计算机在远程位置.
