SafeExecutor
The SafeExecutor decorator allows you to quickly execute a function or method within a try/except block.
Parameter default allows you to override the return value in case of an error.
Parameter logger takes a logger
object and executes the logger.error(error)
method if an error occurs
Examples:
from aghelper.utils import SafeExecutor
from logging import getLogger, StreamHandler, Formatter
logger = getLogger(__name__)
formatter = Formatter("%(asctime)s - %(levelname)s - %(message)s")
sh = StreamHandler()
sh.setFormatter(formatter)
logger.addHandler(sh)

@SafeExecutor

print(f"6. Set default return: {FooClass().change_return()}")
