python-pptx学习总结

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)
