# Manage Bulleted and Numbered Lists in Presentations in Python > Learn how to create and format bulleted, picture, multilevel, and numbered lists in PowerPoint and OpenDocument presentations using Aspose.Slides for Python via .NET. Source: https://docs.aspose.com/slides/python-net/manage-lists/ Updated: 2026-08-05 ## **Overview** Aspose.Slides for Python via .NET lets you create and format bulleted and numbered lists in PowerPoint and OpenDocument presentations. A list item is a paragraph whose bullet settings are controlled through its paragraph format. Use the [Paragraph.paragraph_format](https://reference.aspose.com/slides/python-net/aspose.slides/paragraph/paragraph_format/) property to access paragraph-level list settings. The main entry point is [ParagraphFormat.bullet](https://reference.aspose.com/slides/python-net/aspose.slides/paragraphformat/bullet/), which returns a [BulletFormat](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/) object. With this object, you can set the bullet type, symbol, picture, color, size, numbering style, and starting number. This article shows how to: - create a bulleted list with a custom symbol - create a picture bullet - create a multilevel list by setting paragraph depth - create a numbered list - inspect and change list formatting in an existing presentation ## **Create a Bulleted List** To create a bulleted list, add [Paragraph](https://reference.aspose.com/slides/python-net/aspose.slides/paragraph/) objects to a [TextFrame](https://reference.aspose.com/slides/python-net/aspose.slides/textframe/) and set [BulletFormat.type](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/type/) to [BulletType.SYMBOL](https://reference.aspose.com/slides/python-net/aspose.slides/bullettype/). You can then set [BulletFormat.char](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/char/), [BulletFormat.color](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/color/), and [BulletFormat.height](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/height/) to control the bullet appearance. The following Python code demonstrates how to create a bulleted list in a slide: ```py import aspose.slides as slides import aspose.pydrawing as draw def create_paragraph(text): paragraph = slides.Paragraph() paragraph.paragraph_format.bullet.type = slides.BulletType.SYMBOL paragraph.paragraph_format.bullet.char = '*' paragraph.paragraph_format.indent = 15 paragraph.paragraph_format.bullet.is_bullet_hard_color = slides.NullableBool.TRUE paragraph.paragraph_format.bullet.color.color = draw.Color.indian_red paragraph.paragraph_format.bullet.height = 100 paragraph.text = text return paragraph with slides.Presentation() as presentation: slide = presentation.slides[0] auto_shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 20, 20, 200, 50) text_frame = auto_shape.text_frame text_frame.paragraphs.clear() paragraph1 = create_paragraph("The first paragraph") text_frame.paragraphs.add(paragraph1) paragraph2 = create_paragraph("The second paragraph") text_frame.paragraphs.add(paragraph2) presentation.save("symbol_bullets.pptx", slides.export.SaveFormat.PPTX) ``` The result: ![The symbol bullets](symbol_bullets.png) ## **Create a Numbered List** Use numbered lists when the order of items matters. Set [BulletFormat.type](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/type/) to [BulletType.NUMBERED](https://reference.aspose.com/slides/python-net/aspose.slides/bullettype/). You can also choose a numbering format with [BulletFormat.numbered_bullet_style](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/numbered_bullet_style/) or set [BulletFormat.numbered_bullet_start_with](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/numbered_bullet_start_with/) when the list should start from a value other than 1. The following Python code shows how to create a numbered list in a slide: ```py import aspose.slides as slides with slides.Presentation() as presentation: slide = presentation.slides[0] auto_shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 20, 20, 90, 80) text_frame = auto_shape.text_frame text_frame.paragraphs.clear() paragraph1 = slides.Paragraph() paragraph1.paragraph_format.bullet.type = slides.BulletType.NUMBERED paragraph1.text = "Apple" text_frame.paragraphs.add(paragraph1) paragraph2 = slides.Paragraph() paragraph2.paragraph_format.bullet.type = slides.BulletType.NUMBERED paragraph2.text = "Orange" text_frame.paragraphs.add(paragraph2) paragraph3 = slides.Paragraph() paragraph3.paragraph_format.bullet.type = slides.BulletType.NUMBERED paragraph3.text = "Banana" text_frame.paragraphs.add(paragraph3) presentation.save("numbered_bullets.pptx", slides.export.SaveFormat.PPTX) ``` The result: ![The numbered bullets](numbered_bullets.png) ## **Create a Picture Bullet** Aspose.Slides allows you to replace a regular bullet symbol with an image. Picture bullets work best with simple images that remain readable at a small size, such as icons or small transparent PNG files. {{% alert color="primary" %}} Ideally, if you plan to replace the regular bullet symbol with an image, it's best to choose a simple graphic with a transparent background. Such images work well as custom bullet symbols. Keep in mind that the image will be scaled down to a very small size. For that reason, we strongly recommend selecting an image that remains clear and visually effective when used as a bullet in a list. {{% /alert %}} To create a picture bullet, add an image to [Presentation.images](https://reference.aspose.com/slides/python-net/aspose.slides/presentation/images/) and assign the returned image object to [BulletFormat.picture](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/picture/). Set [BulletFormat.type](https://reference.aspose.com/slides/python-net/aspose.slides/bulletformat/type/) to [BulletType.PICTURE](https://reference.aspose.com/slides/python-net/aspose.slides/bullettype/) before assigning the image. Let's say we have an "image.png": ![A picture for the bullets](picture_for_bullets.png) The following Python code shows how to create picture bullets in a slide: ```py import aspose.slides as slides def create_paragraph(text, image): paragraph = slides.Paragraph() paragraph.paragraph_format.bullet.type = slides.BulletType.PICTURE paragraph.paragraph_format.bullet.picture.image = image paragraph.paragraph_format.indent = 15 paragraph.paragraph_format.bullet.height = 100 paragraph.text = text return paragraph with slides.Presentation() as presentation: slide = presentation.slides[0] auto_shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 20, 20, 200, 50) text_frame = auto_shape.text_frame text_frame.paragraphs.clear() with open("image.png", "rb") as image_stream: bullet_image = presentation.images.add_image(image_stream) paragraph1 = create_paragraph("The first paragraph", bullet_image) text_frame.paragraphs.add(paragraph1) paragraph2 = create_paragraph("The second paragraph", bullet_image) text_frame.paragraphs.add(paragraph2) presentation.save("picture_bullets.pptx", slides.export.SaveFormat.PPTX) ``` The result: ![The picture bullets](picture_bullets.png) ## **Create a Multilevel List** Use [ParagraphFormat.depth](https://reference.aspose.com/slides/python-net/aspose.slides/paragraphformat/depth/) to place list items on different levels. Level 0 is the top level, level 1 is nested below it, and so on. Depth controls indentation only; set [ParagraphFormat.bullet](https://reference.aspose.com/slides/python-net/aspose.slides/paragraphformat/bullet/) on each paragraph when the levels should also carry bullets. The following Python code shows how to create a multilevel list: ```py import aspose.slides as slides with slides.Presentation() as presentation: slide = presentation.slides[0] auto_shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 20, 20, 260, 110) text_frame = auto_shape.text_frame text_frame.paragraphs.clear() paragraph1 = slides.Paragraph() paragraph1.paragraph_format.depth = 0 paragraph1.text = "My text - Depth 0" text_frame.paragraphs.add(paragraph1) paragraph2 = slides.Paragraph() paragraph2.paragraph_format.depth = 1 paragraph2.text = "My text - Depth 1" text_frame.paragraphs.add(paragraph2) paragraph3 = slides.Paragraph() paragraph3.paragraph_format.depth = 2 paragraph3.text = "My text - Depth 2" text_frame.paragraphs.add(paragraph3) paragraph4 = slides.Paragraph() paragraph4.paragraph_format.depth = 3 paragraph4.text = "My text - Depth 3" text_frame.paragraphs.add(paragraph4) presentation.save("multilevel_bullets.pptx", slides.export.SaveFormat.PPTX) ``` The result: ![The multilevel list](multilevel_list.png) ## **Change an Existing List** To change list formatting in an existing presentation, access the target paragraph and update its [ParagraphFormat.bullet](https://reference.aspose.com/slides/python-net/aspose.slides/paragraphformat/bullet/) settings. The same properties used to create lists can be used to inspect or modify lists loaded from a PPT, PPTX, or ODP file. The following Python code changes the first paragraph in a text frame to use a numbered list style: ```py import aspose.slides as slides with slides.Presentation("input.pptx") as presentation: slide = presentation.slides[0] auto_shape = slide.shapes[0] paragraph = auto_shape.text_frame.paragraphs[0] paragraph.paragraph_format.bullet.type = slides.BulletType.NUMBERED paragraph.paragraph_format.bullet.numbered_bullet_style = slides.NumberedBulletStyle.BULLET_ROMAN_UC_PERIOD paragraph.paragraph_format.bullet.numbered_bullet_start_with = 1 paragraph.paragraph_format.margin_left = 30 paragraph.paragraph_format.indent = -20 presentation.save("updated_list.pptx", slides.export.SaveFormat.PPTX) ``` ## **FAQ** ### Can bulleted and numbered lists be exported to PDF or images? Yes. Aspose.Slides preserves list formatting when the target format supports the corresponding text layout and bullet features. ### Can I edit lists in existing presentations? Yes. Load the presentation, access the target paragraph, inspect or update its [ParagraphFormat.bullet](https://reference.aspose.com/slides/python-net/aspose.slides/paragraphformat/bullet/) settings, and save the presentation. ### Can lists contain non-Latin text? Yes. List item text can contain Unicode characters, so you can create lists in multilingual presentations. Make sure the fonts used in the presentation support the characters you need.
