pptx（Microsoft PowerPoint或其他演示程序创建的演示文件）
读取PPT文档
.slides得到一个列表，包含了每个slide
from pptx import Presentation
prs=Presentation('1.pptx')
for slide in prs.slides:
print(slide)
# <pptx.slide.Slide object at 0x000000000345C9F8>
# <pptx.slide.Slide object at 0x000000000345C778>
# <pptx.slide.Slide object at 0x000000000345C278>python-pptx获取形状shape
slide.shapes就可以获取形状
from pptx import Presentation
prs=Presentation('1.pptx')
for slide in prs.slides:
for shape in slide.shapes:
print(shape)
# <pptx.shapes.placeholder.SlidePlaceholder object at 0x000000000345B4C8>
# <pptx.shapes.placeholder.SlidePlaceholder object at 0x000000000345BE88>
# <pptx.shapes.placeholder.SlidePlaceholder object at 0x000000000345B388>
# <pptx.shapes.placeholder.SlidePlaceholder object at 0x000000000345B4C8>
# <pptx.shapes.placeholder.SlidePlaceholder object at 0x000000000345BFC8>
# <pptx.shapes.placeholder.PlaceholderPicture object at 0x000000000345BC88>
判断一个shape中是否存在文字
shape.has_text_frame可以判断是否有文字，shape.text_frame可以获取文字框
from pptx import Presentation
prs=Presentation('1.pptx')
for slide in prs.slides:
for shape in slide.shapes:
if shape.has_text_frame:
text_frame=shape.text_frame
print(text_frame)
# <pptx.text.text.TextFrame object at 0x000000000345BBC8>
# <pptx.text.text.TextFrame object at 0x000000000345BF08>
# <pptx.text.text.TextFrame object at 0x000000000345BBC8>
# <pptx.text.text.TextFrame object at 0x000000000345B2C8>
# <pptx.text.text.TextFrame object at 0x000000000345BBC8>从shape中找paragraphs
text_frame.paragraphs可以获取shape中的段落
from pptx import Presentation
prs=Presentation('1.pptx')
for slide in prs.slides:
for shape in slide.shapes:
if shape.has_text_frame:
text_frame=shape.text_frame
for paragraph in text_frame.paragraphs:
print(paragraph)
# <pptx.text.text._Paragraph object at 0x000000000345B388>
# <pptx.text.text._Paragraph object at 0x000000000345BFC8>
# <pptx.text.text._Paragraph object at 0x0000000003460208>
# <pptx.text.text._Paragraph object at 0x0000000003460308>
# <pptx.text.text._Paragraph object at 0x00000000034602C8>
# <pptx.text.text._Paragraph object at 0x0000000003460348>
# <pptx.text.text._Paragraph object at 0x00000000034605C8>
# <pptx.text.text._Paragraph object at 0x000000000345BFC8>
