Python script works but does not actually update cron. crontab -u -l shows no changes even though code ran without error

from crontab import CronTab
import sys

# Create a new non-installed crontab
cron = CronTab(user='aroth')
job = cron.new(command='/usr/bin/echo')

job.minute.during(5,50).every(5)
job.hour.every(4)

job.dow.on('SUN')
job.month.during('APR', 'JUN')
job.month.also.during('OCT', 'DEC')

job.every(2).days()
job.setall(1, 12, None, None, None)
job.enable()
job2 = cron.new(command='/foo/bar', comment='SomeID')
job2.every_reboot()

jobs = list(cron.find_command('bar'))
job3 = jobs[0]
job3.clear()
job3.minute.every(1)

sys.stdout.write(str(cron.render()))

This works as expected but when I perform crontab -l -u aroth it is blank.

Same thing when I remove a job I don't see it in the render but it is still there when I type crontab -u aroth -l

Is it writing to a different file?
Thanks

Try cron.write() before you exit.
