from docx.oxml import *
from docx.oxml.ns import *

1. Load the document that you want to edit by using the following code:

doc = Document('example.docx')

1. To access the styles in the document.xml, use the following code:

styles = doc.styles

1. Now, you can loop through the styles to access each style's properties:

for style in styles:
    print(style.name)
    print(style.font.name)
    print(style.font.size)

1. You can also apply changes to each style using the following code:

style.font.name = 'Calibri'
style.font.size = Pt(12)

1. Finally, you can save the document by using the following code:

doc.save('example.docx')
