python pptx复制指定页的ppt

Question

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")     

Answer 1

搞定了！

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")   
        

Answer 2

报错了2333
newel = copy.deepcopy(el)
NameError: name 'copy' is not defined
请问copy是个什么呢
