如题，我有一个模板，我想根据需求复制模板中间的某一页多次，比如复制第五页，然后复制3次，那么第六页，第七页，第八页都是和第五页一模一样的ppt，次数是根据我的需求指定的，使用python pptx模块复制，可是不知道有没有相应的方法能实现，我用以下方法行不通：

prs = Presentation("Missed Assessment Rate Template.pptx") 

slide = prs.slides.add_slide(prs.slide_layouts[5])

prs.save("new.pptx")

终于搞定了，实现方法如下：

def duplicate_slide(pres,index):
  
    template = pres.slides[index]
    blank_slide_layout = pres.slide_layouts[index]
    copied_slide = pres.slides.add_slide(blank_slide_layout)

    for shp in template.shapes:
      el = shp.element
      newel = copy.deepcopy(el)
      copied_slide.shapes._spTree.insert_element_before(newel, 'p:extLst')

    for _, value in six.iteritems(template.part.rels):
      # Make sure we don't copy a notesSlide relation as that won't exist
      if "notesSlide" not in value.reltype:
        copied_slide.part.rels.add_relationship(value.reltype,
                        value._target,
                        value.rId)

    return copied_slide
    
    
prs = Presentation("Missed Assessment Rate Template.pptx")
 
for i in range(0,3):
  copied_slide = duplicate_slide(prs, 4)
  

prs.save("new.pptx")
