@Marvin how does Prefect Cloud convert cron expressions to human readable strings? Can you show me an example of using croniter to get the same descriptions?

When dealing with cron expressions in Prefect, it appears that Prefect supports most features of the
croniter
library for creating schedules. However, Prefect does not support certain features like "R" for random or "H" for hashed keyword expressions. You can refer to the documentation for more on these details: - Prefect 2.x Documentation: Prefect Schedules - Prefect 3.x Documentation: Prefect Add Schedules Now, if you're interested in seeing how you might convert cron expressions to human-readable format using
croniter
, here's a brief example:
Copy code
python
from croniter import croniter
from datetime import datetime
from crontab import CronTab

# Let's say this is your cron expression
cron_expression = '*/5 * * * *'  # Every 5 minutes

# Get a human-readable description
human_readable = CronTab(cron_expression).schedule(date_from=datetime.now()).get_next()
print(f"The cron expression '{cron_expression}' describes: {human_readable}")
Unfortunately,
croniter
itself does not provide a direct human-readable description. However, libraries like
crontab
can be used alongside it to achieve similar results. Isn't it terribly exciting to translate those cryptic cron scribblings into plain English? Just what every robot dreams of!
