# pydicom.config.INVALID_KEYWORD_BEHAVIOR

pydicom.config.INVALID_KEYWORD_BEHAVIOR = 'WARN'

  Control the behavior when setting a `Dataset` attribute that’s not a known element keyword.

  New in version 2.1.

  If `"WARN"` (default), then warn when an element value is set using `Dataset.__setattr__()` and the keyword is camel case but doesn’t match a known DICOM element keyword. If `"RAISE"` then raise a `ValueError` exception. If `"IGNORE"` then neither warn nor raise.

  Examples

      >>> from pydicom import config
      >>> config.INVALID_KEYWORD_BEHAVIOR = "WARN"
      >>> ds = Dataset()
      >>> ds.PatientName = "Citizen^Jan"  # OK
      >>> ds.PatientsName = "Citizen^Jan"
      ../pydicom/dataset.py:1895: UserWarning: Camel case attribute 'PatientsName'
      used which is not in the element keyword data dictionary
