Advanced Python Scheduler (APScheduler)

APScheduler is a flexible, in-process task scheduler library for Python, offering cron-like capabilities. It allows you to schedule Python code to be executed later, either once or periodically, within your application. The current stable version is 3.11.2. It supports various scheduler types, job stores (e.g., in-memory, SQLAlchemy, MongoDB), and triggers (date, interval, cron, calendarinterval). APScheduler is primarily meant to be run inside existing applications, not as a standalone daemon. It is actively maintained with a stable 3.x series and an ongoing pre-release 4.x series with significant architectural changes.
