epy.reraise#

etils.epy.reraise( e: Exception, prefix: str | Callable[[], str] | None = None, suffix: str | Callable[[], str] | None = None, ) → NoReturn[source]

Reraise an exception with an additional message.

Benefit: Contrary to raise … from … and raise Exception().with_traceback(tb), this function will:

Keep the original exception type, attributes,…
Avoid multi-nested During handling of the above exception, another exception occurred. Only the single original stacktrace is displayed.

This result in cleaner and more compact error messages.

Usage:

try:
  fn(x)
except Exception as e:
  epy.reraise(e, prefix=f'Error for {x}: ')

Parameters:

e – Exception to reraise
prefix – Prefix to add to the exception message.
suffix – Suffix to add to the exception message.
