scheduled-tasks

问题 In my python program, I would like it to run a piece of code at a pre-defined time every weekday, let say 2pm Mon - Fri. How may I do it please? 回答1: You can use "schedule" library to install, on terminal enter: pip install schedule here is an example of the code you want: #!/usr/bin/python import schedule import time def job(): print("I am doing this job!") schedule.every().monday.at("14:00").do(job) schedule.every().tuesday.at("14:00").do(job) schedule.every().wednesday.at("14:00").do(job)

问题 Say I have a database with a table, each record in this table corresponds with an action to be ececuted. This table has a datetime field in which the next moment the action should be executed is stored. This table is being read by a windows servic and the actions are stored in a datastructure. Every few minutes the service reads the table and new actions are merged into the datastructure, so actions created in the meanwhile don't get missed out. Each action has a certain repeat interval. When

问题 I'm trying to find a package that can do the following in Python: Add/Remove a specified date and time Add/Remove it to a scheduler What I've looked at: https://docs.python.org/2/library/sched.html Looks like it only does time, not dates. https://pypi.python.org/pypi/python-crontab Does reoccurring days but not a specific date. 回答1: You can use sched to do that. sched.add_job(job_func, trigger='interval', hours=3, start_date='2015-10-10 09:30', end_date='2015-11-10 09:30') You can pass

问题 I need to schedule a task via Powershell v2 on Windows Server 2008. I am using the TaskScheduler module from the MS PowershellPack. Scheduling a task is ok, but I need the task to run even nobody is logged on. I saw that this is possible in Powershell v3 on Win8 or Win2k12 (this QA). But that is not my case - I need to this in Powershell version 2. Is this possible with module I am using? Or is there some workaround? 回答1: http://msdn.microsoft.com/en-us/library/windows/desktop/bb736357(v=vs

问题 The project I am working on requires some executions to be done at a certain time. I am not sure what would be the best way to deal with this situation. The method must be able to survive server restart/maintenance. And method calls must be programmatically. I am considering going down this path: I could have a table in database (or even a message queue) called TaskTable which could have TaskID(PK), TaskName(varchar), TaskStatus(enum success,failed, scheduled) and TimeOfExecution. But I need

问题 I am trying to run a .cmd through the task scheduler in windows server 2008 R2.I have logged in to the server from a user who is in the Administrators group in the server machine.When run the scheduled task,the "Last Run Time" column has the value (0x1) while "Status" is ready.and nothing happened.

问题 Is it possible to schedule a function to execute at every xx millisecs in python,without blocking other events/without using delays/without using sleep ? What is the best way to repeatedly execute a function every x seconds in Python? explains how to do it with sched module, but the solution will block the entire code execution for the wait time(like sleep). The simple scheduling like the one given below is non blocking, but the scheduling works only once- rescheduling is not possible. from
