Using lists in PowerPoint allows you to present information in a structured and visually appealing way. They help break down complex ideas into digestible points, making it easier for your audience to understand and retain key concepts. Whether you're creating a slide deck for a business presentation, educational workshop, or conference talk, incorporating lists can enhance the visual appeal and effectiveness of your content. In this article, we will demonstrate how to create numbered lists and bulleted lists in PowerPoint presentations in Python using Spire.Presentation for Python.

Create a Numbered List in PowerPoint in Python
Spire.Presentation supports adding numerals or bullet points in front of paragraphs to create a numbered or bulleted list. To specify the bullet type, you can use the ParagraphProperties.BulletType property. The following are the steps to create a numbered list in a PowerPoint slide using Spire.Presentation for Python.
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the numbered list inside a list.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Numbered using ParagraphProperties.BulletType property.
- Set the numbered bullet style of these paragraphs using ParagraphProperties.BulletStyle property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import *
from spire.presentation import *
# Create an object of the Presentation class
presentation = Presentation()
# Get the first slide
slide = presentation.Slides[0]
# Add a shape to the slide and set the shape style
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF(50.0, 50.0, 300.0, 200.0))
shape.Fill.FillType = FillFormatType.none
shape.Line.FillType= FillFormatType.none
# Add text to the default paragraph
paragraph = shape.TextFrame.Paragraphs[0]
paragraph.Text = "Required Web Development Skills:"
paragraph.Alignment = TextAlignmentType.Left
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
# Specify the list items
listItems = [
" Command-line Unix",
" Vim",
" HTML",
" CSS",
" Python",
" JavaScript",
" SQL"
]
# Create a numbered list
for item in listItems:
textParagraph = TextParagraph()
textParagraph.Text = item
textParagraph.Alignment = TextAlignmentType.Left
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
textParagraph.BulletType = TextBulletType.Numbered
textParagraph.BulletStyle = NumberedBulletStyle.BulletArabicPeriod
shape.TextFrame.Paragraphs.Append(textParagraph)
# Save the result document
presentation.SaveToFile("NumberedList.pptx", FileFormat.Pptx2013)
presentation.Dispose()
Create a Bulleted List with Symbol Bullets in PowerPoint in Python
The process of creating a bulleted list with symbol bullets is very similar to that of creating a numbered list. The only difference is that you need to set the bullet type of the paragraphs to Symbol. The following are the steps.
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the bulleted list inside a list.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Symbol using ParagraphProperties.BulletType property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import *
from spire.presentation import *
# Create an object of the Presentation class
presentation = Presentation()
# Get the first slide
slide = presentation.Slides[0]
# Add a shape to the slide and set the shape style
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF(50.0, 50.0, 350.0, 200.0))
shape.Fill.FillType = FillFormatType.none
shape.Line.FillType = FillFormatType.none
# Add text to the default paragraph
paragraph = shape.TextFrame.Paragraphs[0]
paragraph.Text = "Computer Science Subjects:"
paragraph.Alignment = TextAlignmentType.Left
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
# Specify the list items
listItems = [
" Data Structure",
" Algorithm",
" Computer Networks",
" Operating System",
" Theory of Computations",
" C Programming",
" Computer Organization and Architecture"
]
# Create a symbol bulleted list
for item in listItems:
textParagraph = TextParagraph()
textParagraph.Text = item
textParagraph.Alignment = TextAlignmentType.Left
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
textParagraph.BulletType = TextBulletType.Symbol
shape.TextFrame.Paragraphs.Append(textParagraph)
# Save the result document
presentation.SaveToFile("SymbolBulletedList.pptx", FileFormat.Pptx2013)
presentation.Dispose()
Create a Bulleted List with Image Bullets in PowerPoint in Python
To use an image as bullets, you need to set the bullet type of the paragraphs to Picture and then set the image as bullet points using the ParagraphProperties.BulletPicture.EmbedImage property. The following are the detailed steps.
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the bulleted list inside a list.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Picture using ParagraphProperties.BulletType property.
- Set an image as bullet points using ParagraphProperties.BulletPicture.EmbedImage property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import *
from spire.presentation import *
# Create an object of the Presentation class
presentation = Presentation()
# Get the first slide
slide = presentation.Slides[0]
# Add a shape to the slide and set the shape style
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF(50.0, 50.0, 400.0, 180.0))
shape.Fill.FillType = FillFormatType.none
shape.Line.FillType = FillFormatType.none
# Add text to the default paragraph
paragraph = shape.TextFrame.Paragraphs[0]
paragraph.Text = "Project Task To-Do List:"
paragraph.Alignment = TextAlignmentType.Left
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
# Specify the list items
listItems = [
" Define projects and tasks you're working on",
" Assign people to tasks",
" Define the priority levels of your tasks",
" Keep track of the progress status of your tasks",
" Mark tasks as done when completed"
]
# Create an image bulleted list
for item in listItems:
textParagraph = TextParagraph()
textParagraph.Text = item
textParagraph.Alignment = TextAlignmentType.Left
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.get_Black()
textParagraph.BulletType = TextBulletType.Picture
stream = Stream("icon.png")
imageData = presentation.Images.AppendStream(stream)
textParagraph.BulletPicture.EmbedImage = imageData
shape.TextFrame.Paragraphs.Append(textParagraph)
stream.Close()
# Save the result document
presentation.SaveToFile("ImageBulletedList.pptx", FileFormat.Pptx2013)
presentation.Dispose()
