python-pptx学习总结
时间：2022-10-01 11:00:00
最近ppt排版太麻烦了。每次都要贴截图，不容易对齐。看起来很不舒服。一旦结果更新，就要重新贴截图。我觉得太麻烦了。我以前知道这个python-pptx,我能自动排版图片吗？答案是肯定的。以下是我的学习记录。
安装python-pptx
网上有很多教程，就不说了，

python pptx 操作实例1(新建ppt)
from pptx import Presentation ppt=Presentation() ppt.slides.add_slide(ppt.slide_layouts[0]) ppt.save("测试1.pptx") ## 添加个换灯片 python pptx 基本操作
from pptx import Presentation prs = Presentation('test_template.pptx') for slide in prs.slides: print(slide) from pptx import Presentation prs = Presentation('test_template.pptx') for slide in prs.slides: for shape in slide.shapes: print(shape) # 获取所有Slide中的内容 from pptx import Presentation prs = Presentation('test_template.pptx') for slide in prs.slides: for shape in slide.shapes: if shape.has_text_frame: text_frame = shape.text_frame print(text_frame.text) # 获取某一页Slide中的内容 from pptx import Presentation prs = Presentation('test_template.pptx') for i, slide in enumerate(prs.slides): if i == 2:
for shape in slide.shapes:
if shape.has_text_frame:
text_frame = shape.text_frame
print(text_frame.text)

python pptx使用案例2(占位符使用）
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from pptx import Presentation
prs = Presentation()
title_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_slide_layout)

title.text = "Hello, World!"
subtitle.text = "python-pptx 可以轻松制作powerpoint!"

python-pptx使用案例3 插入形状
from pptx import Presentation

from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN
from pptx.enum.shapes import MSO_SHAPE
ppt = Presentation(r'测试1.pptx')
slide = ppt.slides[0]#更改第一张
# 添加矩形
# 设置位置以及大小
left, top, width, height = Cm(0), Cm(0), Cm(2), Cm(2)
# 添加形状
rectangle = slide.shapes.add_shape(MSO_SHAPE.RECTANGLE, left, top, width, height)
# 设置背景填充
rectangle.fill.solid()
# 设置背景颜色
rectangle.fill.fore_color.rgb = RGBColor(34, 134, 165)
# 设置边框颜色
rectangle.line.color.rgb = RGBColor(34, 134, 165)
ppt.save('测试1.pptx')
