Limit the function execution time
This module provides a decorator which runs the function in a separate multiprocessing.Process and sends SIGKILL after the specified timeout if the function didn't complete.
Requirements
- Python 3.7+ (needed for multiprocessing.Process.kill)
- tblib (to pass the traceback from separate process)
Install
pip install kill-timeoutUsage
from kill_timeout import kill_timeout
limit_in_seconds = 5
@kill_timeout(limit_in_seconds)

"""Function which makes some computations
It could take too long for some parameters.

except TimeoutError:
print("Function didn't finished in %d seconds" % limit_in_seconds)
except Exception:
