In this code you can see an example to insert an image in Powerpoint with Python and the module python-pptx.<\/p>\n\n\n\n

The python pptx module can be seen through this scheme:<\/p>\n\n\n

\n
\"\"<\/a><\/figure>\n<\/div>\n\n\n

Old code may not work with python 3.10<\/h2>\n\n\n\n

The code below may not work anymore<\/p>\n\n\n\n

from pptx import Presentation\nimport os\n\nprs = Presentation()\nslide = prs.slides.add_slide(prs.slide_layouts[8])\nplaceholder = slide.placeholders[1]\npicture = placeholder.insert_picture('001.png')\nprs.save(\"ESEMPIO.pptx\")\nos.startfile(\"ESEMPIO.pptx\")<\/pre>\n\n\n\n
Workaround to <\/a>AttributeError: module ‘collections’ has no attribute ‘Container’<\/h2>\n\n\n\n
With python 3.10, this code does not work. There is a workaround as you can see here<\/a>.<\/p>\n\n\n\n
import collections \nimport collections.abc\nfrom pptx import Presentation\nimport os\n\nprs = Presentation()\nslide = prs.slides.add_slide(prs.slide_layouts[8])\nplaceholder = slide.placeholders[1]\npicture = placeholder.insert_picture('001.png')\nprs.save(\"ESEMPIO.pptx\")\nos.startfile(\"ESEMPIO.pptx\")<\/pre>\n\n\n\n
Now it should work.<\/p>\n\n\n\n
The code that fits the image in the placeholder<\/h2>\n\n\n\n
This is the code to add to make the image fit.<\/p>\n\n\n\n
And this is the code to make the slides with the _add_image that uses the code above, replacing the slide.splaceholders[1].add_picture(‘…png’) stuff.<\/p>\n\n\n\n
