Easily schedule multiple events and recurring tasks (simultaneously in background).
Project description
simple_scheduler
- Does not miss future events.
- Uses multiprocessing to schedule jobs.
- This package uses a 24-hour clock, only.
- Simultaneously schedule any number of jobs.
- Recurring jobs to be precisely sheduled.
- Event jobs to be executed within the minute.
- Long jobs to be executed even if previous call(s) is(are) still running.
Install
From PyPi :
pip install simple-scheduler
How to use?
Quick-start
See [examples](https://github.com/Vernal-Inertia/simple_scheduler/tree/main/examples/)
Long
There are two different schedulers:
>>> from simple_scheduler.event import event_scheduler
>>> from simple_scheduler.recurring import recurring_scheduler
Purpose of each scheduler:
>>> print(event_scheduler.__doc__)
Event occurs at an exact time.
e.g. scirpt_1 is called at 14:00 and 20:00
Each event is tried 3-times (but executed only once).
>>> print(recurring_scheduler.__doc__)
Recurring tasks are those that occur after every "x"-seconds.
(e.g. script_1 is called every 600 seconds)
Using only recurrent_scheduler
>>> print(recurring_scheduler.add_job.__doc__)
Assigns an periodic task to a process.
Parameters
----------
target : a callable function
period_in_seconds : int
the time period in seconds to execute this function
args : tuple(object,), optional
un-named argumets for the "target" callable
the default is ()
job_name : str, optional
used to identify a job, defaults to name of the function
to remove jobs use this name
kwargs : dict{key:object}, optional
named argumets for the "target" callable
the default is {}
Returns
-------
None.
Using only event_scheduler
>>> print(event_scheduler.add_job.__doc__)
Assigns an event to a process.
Parameters
----------
target : a callable function
tz : str
time zone (call the method .timezones() for more info)
when : list, a collection of "day|HH:MM"
at what precise time(s) should the function be called
eg. ["mon|22:04","*|03:45", ...] please "only" use 24-hour
clock with "|" as day separator
and ":" as time separator
job_name : str, optional
used to identify a job, defaults to name of the function
to remove jobs use this name
number_of_reattempts : int, optional
defailt is 3
each event is tried these many number of times, but executed once
reattempt_duration : int, optional
default is 10 secs
duration to wait (in seconds) after un-successful attempt
args : tuple(object,), optional
un-named argumets for the "target" callable
the default is ()
kwargs : dict{key:object}, optional
named argumets for the "target" callable
the default is {}
Raises
------
Exception
- If time (in "when"-list) is not a collection of "day|HH:MM"
i.e. *|HH:MM, *|HH:MM, *|*H:MM,, *|*H:MM, *|**:MM, *|**:*M, *|**:M*'
eg. ["tue|12:30am","thu|2:30 pm", ...] please "only" use 24-hour
clock, with "|" as day
separator and ":" as time
separator
Returns
-------
None.
Toggle verbose
>>> event_scheduler.verbose = False
>>> recurring_scheduler.verbose = True
Job summary (before and after jobs are run)
>>> event_scheduler.job_summary()
>>> recurring_scheduler.job_summary()
Number of reattempts in case event fails [fallback]
>>> event_scheduler.add_job(number_of_reattempts = 3)
Reattempt duration(in seconds) between each reattempt [fallback]
>>> event_scheduler.add_job(reattempt_duration = 10)
Remove jobs
>>> event_scheduler.remove_job(job_name)
>>> recurring_scheduler.remove_job(job_name)
Clear schedule
>>> event_scheduler.clear()
>>> recurring_scheduler.clear()
