• Create an object of the Document class.
• Add a section to the document using Document.AddSection() method.
• Add a paragraph to the section using Section.AddParagraph() method.
• Add normal text to the paragraph using Paragraph.AppendText() method.
• Add superscript or subscript text to the paragraph using Paragraph.AppendText() method.
• Apply superscript or subscript formatting to the superscript or subscript text using TextRange.CharacterFormat.SubSuperScript property.
• Save the resulting document using Document.SaveToFile() method.

from spire.doc import *
from spire.doc.common import *

# Create a Document instance
document = Document()
# Add a section to the document
section = document.AddSection()

# Add a paragraph to the section
paragraph = section.AddParagraph()

# Add normal text to the paragraph
paragraph.AppendText("E = mc")
# Add superscript text to the paragraph
superscript_text = paragraph.AppendText("2")
# Apply superscript formatting to the superscript text
superscript_text.CharacterFormat.SubSuperScript = SubSuperScript.SuperScript

# Start a new line
paragraph.AppendBreak(BreakType.LineBreak)

# Add normal text to the paragraph
paragraph.AppendText("H")
# Add subscript text to the paragraph
subscript_text = paragraph.AppendText("2")
# Apply subscript formatting to the subscript text
subscript_text.CharacterFormat.SubSuperScript = SubSuperScript.SubScript
# Add normal text to the paragraph
paragraph.AppendText("O")

# Set the font size for the text in the paragraph
for i in range(paragraph.Items.Count):
    item = paragraph.Items[i]
    if isinstance(item, TextRange):
        text_range = item

• Calculate the ratio for resetting the size and position of the shapes based on the original and new slide heights and widths.
• Iterate through the slides in the presentation and the shapes on each slide.
• Reset the size and position of each shape based on the specified ratio using IShape.Height, IShape.Width, IShape.Left and IShape.Top properties.
• Save the resulting presentation using Presentation.SaveToFile() method.

from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("ShapeTemplate.pptx")

# Get the original slide height and width
currentHeight = ppt.SlideSize.Size.Height
currentWidth = ppt.SlideSize.Size.Width

# Change the slide size to A3
ppt.SlideSize.Type = SlideSizeType.A3

# Get the new slide height and width
newHeight = ppt.SlideSize.Size.Height
newWidth = ppt.SlideSize.Size.Width

# Calculate the ratio for resizing shapes based on the original and new slide heights and widths
ratioHeight = newHeight / currentHeight
ratioWidth = newWidth / currentWidth

# Iterate through the slides in the presentation
for slide in ppt.Slides:
    # Iterate through the shapes on the slide
    for shape in slide.Shapes:
        if isinstance(shape, IAutoShape):
            # Reset the size of the shape based on the specified ratio
            shape.Height = shape.Height * ratioHeight
            shape.Width = shape.Width * ratioWidth
            # Reset the position (x and y coordinates) of the shape based on the specified ratio
            shape.Top = shape.Top * ratioHeight
            shape.Left = shape.Left * ratioWidth
                
# Save the resulting presentation to a new file
ppt.SaveToFile("ResizeAndRepositionShapes.pptx", FileFormat.Pptx2016)
ppt.Dispose()

Reorder Shapes in PowerPoint in Python
