What does '=\' operator mean in Python

so there is this piece of code I am trying to understand:

rois, target_class_ids, target_bbox, target_mask =\
                DetectionTargetLayer(config, name="proposal_targets")([
                    target_rois, input_gt_class_ids, gt_boxes, input_gt_masks])

DetectionTargetLayer is a Keras subclass layer. So what does the operator =\ mean? Is it just the same as ‘=’?

>Solution :

That’s not an operator, the \ is a line continuation chararacter. It splits the line after the = and allows it continue on the next line. PEP8 standards say to keep lines under 120 characters, and this line is pretty long, so the author broke it after the =.
