问题描述
我想使用Windows平台上的python-crontab模块安排python脚本.找到了以下代码片段可以解决,但配置起来很困难.脚本名称 cronTest.py
:
I want to schedule a python script using the python-crontab module on Windows platform. Found the following snippet to work around but having a hard time to configure. Script name cronTest.py
:
from crontab import CronTab
file_cron = CronTab(tabfile='filename.tab')
mem_cron = CronTab(tab="""
* * * * * command
""")
例如,假设我要打印日期&使用以下名为 dateTime.py
的脚本的时间为5分钟:
Let's say, for example, I want to print date & time for ever 5 mins using the following script, named dateTime.py
:
import datetime
with open('dateInfo.txt','a') as outFile:
outFile.write('\n' + str(datetime.datetime.now()))
如何执行 dateTime.py
并通过 cronTest.py
每5分钟设置一次cron作业.
How do I execute dateTime.py
and setup the cron job for every 5mins through cronTest.py
.
推荐答案
您是否运行了嵌入式调度程序?请参见文档中的运行调度程序
部分:
Did you run the embedded scheduler? See Running the Scheduler
section in the documentation:
tab = CronTab(tabfile='MyScripts.tab')
for result in tab.run_scheduler():
print "This was printed to stdout by the process."
由于Windows没有crontab进程,因此您必须将crontabs馈送到现有的守护程序中,或者在进程中使用此run_scheduler为自己创建一个守护程序.
Because windows doesn't have a crontab process, you have to either feed your crontabs into an existing daemon or use this run_scheduler within your process to create a daemon for yourself.
