tryagain.call(func, max_attempts=None, exceptions=<class 'Exception'>, wait=0.0, cleanup_hook=None, pre_retry_hook=None)¶ Parameters: - (callable) (func) – The function to retry. No arguments are passed to this function. If your function requires arguments, consider defining a separate function or use functools.partial / a lambda function.
- max_attempts – Any integer number to limit the maximum number of attempts. Set to None for unlimited retries.
- exceptions – A tuple of exceptions that should result in a retry.
- wait – This can be an integer / float to specify the waittime in seconds before the next attempt. You can also pass a function which accepts a single argument ‘attempt’.
- cleanup_hook – Can be set to a callable and will be called after an exception is raised from calling func. No arguments are passed to this function. If your function requires arguments, consider defining a separate function or use functools.partial / a lambda function.
- pre_retry_hook – Can be set to any callable that will be called before function is called. No arguments are passed to this function. If your function requires arguments, consider defining a separate function or use functools.partial / a lambda function. If wait is set, pre_retry_hook will be called before the waittime. Exceptions that are raised when calling this hook are not caught.
Returns: The result of calling the given func.
Raises: - Any exception which is
- not in the given exceptions
- raised in pre_retry_hook or in cleanup_hook
- raised in the last attempt at calling func
