slides = list ( prs . slides . _sldIdLst ) prs . slides . _sldIdLst . remove ( slides [ 1 ] ) # 删除 prs . slides . _sldIdLst . append ( slides [ 1 ] ) # 添加 prs . save ( r "test2.pptx" )

注：多次append是没用的，不能用来复制ppt；
另外也可用以下方式删除ppt；

del prs.slides._sldIdLst[index] #index是ppt序号

python-pptx 复制ppt；
 
# -*- coding = UTF-8 -*-
import pptx
import copy
from pptx import Presentation
prs = Presentation(r"test.pptx")
def duplicate_slide(pres,index):
    slide = pres.slides[index]
    blank_slide_layout = pres.slide_layouts[6] #空白页
    copied_slide = pres.slides.add_slide(blank_slide_layout)
    for shape in slide.shapes:
        el = shape.element
        newel = copy.deepcopy(el)
        copied_slide.shapes._spTree.insert_element_before(newel, 'p:extLst')
    for value in slide.part.rels.values():
        # 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
copied_slide = duplicate_slide(prs, 1)
prs.save(r"test2.pptx")
