is there a way to center text?

document.add_picture(img, width=Inches(7))
fileName,extension=os.path.splitext(img)
capt='Figure %d,Meter number %s' % (figureNum, fileName)
c=document.add_paragraph(capt, style='Caption')

Now I would like the caption to be centered on the page?

<w:pStyle w:val="Caption"/>
<w:jc w:val="center"/>
