Reportlab - how to introduce line break if the paragraph is too long for a line

I have a list of text to be added to a reportlab frame

style = getSampleStyleSheet()['Normal']
style.wordWrap = 'LTR'
style.leading = 12
for legend in legends:
    elements.append(Paragraph(str(legend),style))

If the legend is too long, the text at the end is not visible at all. How to introduce line breaks in this situation.
