Scheduling Python script using Python CronTab on Windows 7

问题

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
""")

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()))

How do I execute dateTime.py and setup the cron job for every 5mins through cronTest.py.

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."

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.
