13. API - Exceptions

All exceptions defined by picamera are listed in this section. All exception classes utilize multiple inheritance in order to make testing for exception types more intuitive. For example, PiCameraValueError derives from both PiCameraError and ValueError. Hence it will be caught by blocks intended to catch any error specific to the picamera library:

    camera.brightness = int(some_user_value)
except PiCameraError:
    print('Something went wrong with the camera')

Or by blocks intended to catch value errors:

    camera.contrast = int(some_user_value)
except ValueError:
    print('Invalid value')
