Mac OSX上自运行的Python脚本的体系结构

Question

I have the following set-up

1. A Python script
2. A Mac OSX Automator application with said script
3. An iCal alert that runs the Automator (and thus the Python script) on a regular schedule

All of the above works just fine. But I need to make a change. I need the script to check a web site for a time in the future (that same day) and then come back prior to that time and run itself again. I know how to do the first part (get the time) but I have no clue how to do the second part. How do you get a Python script to (1) run itself at a regular time and then (2) run again at some point in the future? The point in the future will change on a regular basis. Sometimes it would be as early as 10AM, other times it may be 7PM.

Any thoughts on this and pseudo-code are welcome. Thanks!

Answer 1

You don't need to hard-code anything in - use crontab to schedule when your script first runs. It checks the website for the time it's supposed to run again, then you call time.sleep() until the task needs to run again.

Answer 2

将变量设置为将来的时间，并在while（）循环中进行检查
