  ppt = Presentation()

  2、 Insert ppt page

  slide_1 = ppt.slides.add_slide(ppt.slide_layouts[0]) Insert a slide , Use layout 0
  shape_1 = slide_1.shapes.placeholders # Get this page ppt All placeholders for
  shape_1[0].text = ‘ Place holder ’ # Yes shape[0] Write content
  shape_1[1].text = ‘Python operation PPT’ # Yes shape[1] Write content

  3、 Save the file ：

  ppt.save(‘python.pptx’)

  Complete code ：

  def create():''' establish ppt'''from pptx import Presentationfrom pptx.util import Inches,Ptppt = Presentation() # initialization ppt#------------------# first page PPTslide_1 = ppt.slides.add_slide(ppt.slide_layouts[0]) # Insert a slide , Use layout 0shape_1 = slide_1.shapes.placeholders # Get this page ppt All placeholders for shape_1[0].text = ' Place holder ' # Yes shape[0] Write content shape_1[1].text = 'Python operation PPT' # Yes shape[1] Write content #------------------##------------------# The second page PPTslide_3 = ppt.slides.add_slide(ppt.slide_layouts[5]) # Insert a slide , Use layout 5slide_3.shapes.placeholders[0].text = 'test' # Yes, page three PPT One of the first shape Write content picture = slide_3.shapes.add_picture('picture.jpg',left=Inches(3.2),top=Inches(2),width=Inches(3.5),height=Inches(5)) # Insert a picture #------------------##------------------# Page four PPTslide_4 = ppt.slides.add_slide(ppt.slide_layouts[6]) # Insert a slide , Use layout 6table = slide_4.shapes.add_table(rows=2,cols=2,left=Inches(2),top=Inches(2),width=Inches(5),height=Inches(2)).table # Insert table table.columns[0].width = Inches(2) # Set the first 0 The width of the column table.columns[1].width = Inches(3) # Set the first 1 The width of the column # Add content table.cell(0,0).text = 'ppt'table.cell(0,1).text = ' Corresponding library 'table.cell(1,0).text = 'Python'table.cell(1,1).text = 'python-pptx'#------------------#ppt.save('python.pptx')

• update operation ：
  First, create a ppt, Adjust the format , And then through python modify
  

• Get a collection of methods for various placeholders

Get this page ppt All placeholders for ：shape = slide.shapes.placeholders # Place holder ：placeholders
Yes shape[num] Write content ：shape[num].text = ‘xx’
Get this page ppt The title of shape：title_shape = slide.shapes.title
To the title shape Write content ：title_shape.text = ‘xx’
stay shape[num] Add paragraph ：para = shape[num].text_frame.add_paragraph()
Write to the paragraph ：para.text = ‘xx’
Set whether the paragraph font is bold ：para.font.blod = True
Set paragraph font size ：para.font.size = Pt(num)
Set whether to add font underline to paragraphs ：para.font.underline = True
Insert text box ：textBox = slide.shapes.add_textbox(left,top,width,height)
Insert a picture ：picture = slide.shapes.add_picture(‘ picture ’,left,top,width,height)
Insert table ：table = slide.shapes.add_table(rows=num,cols=num,left,top,width,height).table
Set table number n The width of the column :table.columns[n].width = Inches(num)
Table cell write content ：table.cell(x,y).text = ‘xx’
