本文主要介绍如何通过python生成ppt文件，以及借助ppt模板来生成ppt

环境

python 3
python-pptx

安装

将文字输出到ppt

效果图

代码

from pptx import Presentation# 创建幻灯片 ------prs = Presentation()title_slide_layout = prs.slide_layouts[0]slide = prs.slides.add_slide(title_slide_layout)title = slide.shapes.titlesubtitle = slide.placeholders[1]# 设置标题和副标题title.text = "Hello, World!"subtitle.text = "pip install python-pptx"prs.save("test.pptx")
