Method Details

emit(cls, message, stacklevel=1)
Class Method


Emit a warning of this very category

This method is pure convenience. It saves you the unfriendly warnings.warn syntax (and the warnings import).

  • message (any) - The warning message
  • stacklevel (int) - Number of stackframes to go up in order to place the warning source. This is useful for generic warning-emitting helper functions. The stacklevel of this helper function is already taken into account.
