我尝试了什么：



i尝试睡眠功能，它只是推迟了工作

解决方案

您只需要捕获函数启动的时间，然后定期检查它是否已达到其时间限制。然后你睡觉分配休息时间，然后重复整个过程。请参见 15.3。时间 - 时间访问和转换& mdash; Python 2.7.12文档 [ ^ ]

i tried sleep function and it's only delaying the work

解决方案

You just need to capture the time when your function starts, and then periodically check whether it has reached its time limit. you then sleep for the allotted rest time and then repeat the whole process. See 15.3. time — Time access and conversions — Python 2.7.12 documentation[^].
