A context manager that suppresses exceptions (like contextlib.suppress) and instead evokes warnings. Implementation idea by @alonhorev.

warn_and_suppress.py

import contextlib

class ExceptionWarning(Warning):
	pass

@contextlib.contextmanager
def warn_and_suppress(*exceptions):
	try:
		yield
	except exceptions as e:
		import warnings
		warnings.warn(str(e), ExceptionWarning, stacklevel=2)

if __name__ == '__main__':
	with warn_and_suppress(ZeroDivisionError):
		a = 1 / 0

	with warn_and_suppress(FileNotFoundError, FileExistsError):
		b = 5 / 0
