How to correctly break a long line in Python?

Question

How would I go about breaking the following line? The PEP8 guideline doesn't make it very clear to me.

confirmation_message = _('ORDER_CREATED: %(PROPERTY_1)s - %(PROPERTY_2)s - %(PROPERTY_3)s - %(PROPERTY_4)s')  % {'PROPERTY_1': order.lorem, 'PROPERTY_2': order.ipsum, 'PROPERTY_4': order.dolor, 'PROPERTY_5': order.sit}

Answer 1

One would typically do something like:

confirmation_message = _(
    'ORDER_CREATED: %(PROPERTY_1)s - '
    '%(PROPERTY_2)s - %(PROPERTY_3)s - %(PROPERTY_4)s') % {
        'PROPERTY_1': order.lorem,
        'PROPERTY_2': order.ipsum,
        'PROPERTY_3': order.ipsum,
        'PROPERTY_4': order.dolor,
        'PROPERTY_5': order.sit
    }

This takes advantage of the fact that adjacent strings ('like ' 'this') are concatenated to shorten the long line of text; everything else is split on commas.
