We have already learnt how to schedule cron job manually. Now we will schedule cron job using python code.

Create an empty python file with .py entension.

Paste following code step by step:


# Create CronTab instance.
cron = CronTab(user=True) 

# Remove all previous jobs having comment id 'My_Job'
cron.remove_all(comment='My_Job')

# Schedule new job having comment id 'My_Job'
job = cron.new(comment='My_Job', command='/usr/bin/python3 /home/root/Schedular/scheduleCronJob.py >> /home/root/Schedular/Logs.txt')
