Python 2.7 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Python
2.7 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Python.

google.appengine.api.croninfo module
Summary
CronInfo tools.
A library for working with CronInfo records, describing cron entries for an
application. Supports loading the records from yaml.
Contents
- class google.appengine.api.croninfo.CronEntry(**attributes)source
-
Bases: google.appengine.api.validation.Validated
A cron entry describes a single cron job.
- ATTRIBUTES = {u'retry_parameters': <google.appengine.api.validation.Optional object>, u'schedule': <google.appengine.api.croninfo.GrocValidator object>, u'url': u'^/.*$', u'description': <google.appengine.api.validation.Optional object>, u'timezone': <google.appengine.api.croninfo.TimezoneValidator object>, u'target': <google.appengine.api.validation.Optional object>}
- class google.appengine.api.croninfo.CronInfoExternal(**attributes)source
-
Bases: google.appengine.api.validation.Validated
CronInfoExternal describes all cron entries for an application.
- ATTRIBUTES = {u'cron': <google.appengine.api.validation.Optional object>, 'application': <google.appengine.api.validation.Optional object>}
- google.appengine.api.croninfo.LoadSingleCron(cron_info, open_fn=None)source
-
Load a cron.yaml file or string and return a CronInfoExternal object.
- class google.appengine.api.croninfo.RetryParameters(**attributes)source
-
Bases: google.appengine.api.validation.Validated
Retry parameters for a single cron job.
- ATTRIBUTES = {u'min_backoff_seconds': <google.appengine.api.validation.Optional object>, u'job_age_limit': <google.appengine.api.validation.Optional object>, u'job_retry_limit': <google.appengine.api.validation.Optional object>, u'max_backoff_seconds': <google.appengine.api.validation.Optional object>, u'max_doublings': <google.appengine.api.validation.Optional object>}
