python-pptx的使用首先需要了解几个基本概念：
1.引入python-pptx
from pptx import presentation
# 实例化Presentation
prs = Presentation()
2.ppt模板的选择
a、使用ppt自带的模板
prs = Presentation()
prs.slide_layouts[index]
ppt自带了常用的1-48种模板通过index选择对应的模板
b、使用自定义ppt模板
prs = Presentation('template.pptx')
3.新建一页幻灯片
slide = prs.slides.add_slide(prs.slide_layouts[1])
# prs.slides.add_slide()增加一页幻灯片方法
4.编辑幻灯中的元素
a、根据placeholdes索引获取一页幻灯片中的元素
body_shape = slide.shapes.placeholders
# body_shape为本页ppt中所有shapes
body_shape[0].text = 'this is placeholders[0]'
body_shape[1].text = 'this is placeholders[1]'
在ppt中所有的元素均被当成一个shape，slide.shapes表示幻灯片类中的模型类，placeholders中为每个模型，采用slide_layouts[1]中包含两个文本框，所以printlen(slide.shapes.placeholders) 话为2
b、获取幻灯片中的title元素(本页幻灯片必须含有标题元素才能通过此方法获取)
title_shape = slide.shapes.title
# 获取本页ppt的title元素
title_shape.text = 'this is a title'
c、在本页幻灯片中新增元素
new_paragraph = body_shape[1].text_frame.add_paragraph()
# 在第二个shape中的文本框中添加新段落
new_paragraph.text = 'add_paragraph'#新段落中的文字
ew_paragraph.font.bold = True # 文字加粗
new_paragraph.font.italic = True # 文字斜体
from pptx.util import Pt #设置文字大小必须引入pptx.util中的Pt
new_paragraph.font.size = Pt(15) # 文字大小
new_paragraph.font.underline = True # 文字下划线new_paragraph.level = 1 # 新段落的级别
5.新增幻灯中的元素
a、添加新文本框
from pptx.util import Inches
left = top = width = height = Inches(5)
# 预设位置及大小
textbox = slide.shapes.add_textbox(left, top, width, height)
# left，top为相对位置，width，height为文本框大小
textbox.text = 'this is a new textbox'
# 文本框中文字
new_para = textbox.text_frame.add_paragraph()
# 在新文本框中添加段落
new_para.text = 'this is second para in textbox'
# 段落文字
b、添加图片
img_path = 'img_path.jpg'
# 文件路径
left, top, width, height = Inches(1), Inches(4.5), Inches(2), Inches(2)
# 预设位置及大小
pic = slide.shapes.add_picture(img_path, left, top, width, height)
# 在指定位置按预设值添加图片
c、添加形状
from pptx.enum.shapes import MSO_SHAPE
left, top, width, height = Inches(1), Inches(3), Inches(1.8), Inches(1)
# 预设位置及大小
shape = slide.shapes.add_shape(MSO_SHAPE.PENTAGON, left, top, width, height)
# 在指定位置按预设值添加类型为PENTAGON的形状
shape.text = 'Step 1'
for n in range(2, 6):
left = left + width - Inches(0.3)
shape = slide.shapes.add_shape(MSO_SHAPE.CHEVRON, left, top, width, height)
shape.text = 'Step{}'.format(n)
d、添加表格
rows, cols, left, top, width, height = 2, 2, Inches(3.5), Inches(4.5), Inches(6), Inches(0.8)
table = slide.shapes.add_table(rows, cols, left, top, width, height).table
# 添加表格，并取表格类
table.columns[0].width = Inches(2.0)
# 第一纵列宽度
table.columns[1].width = Inches(4.0)
# 第二纵列宽度
table.cell(0, 0).text = 'text00'
# 指定位置写入文本
table.cell(0, 1).text = 'text01'
table.cell(1, 0).text = 'text10'
table.cell(1, 1).text = 'text11'
d、添加图表chart类
#!/usr/bin/env python
# encoding: utf-8
