如何使用 python-docx 更改所有 .docx 文档的字体大小

Question

So, Im trying to solve problem with Python Docx. I need to refactor my .docx document, I need to change Font Name and Font Size of all document. What solutions can you suggest?

With this code Font Name are changing, but Font Size are not.

from docx import Document
from docx.shared import Pt
document = Document('path/to/file.docx')


style = document.styles['Normal']
font = style.font
font.name = 'Arial'
font.size = Pt(10)
for paragraph in document.paragraphs:
    paragraph.style = document.styles['Normal']
document.save('refactored.docx')

Answer 1

You need to iterate over runs for font changes.

for paragraph in document.paragraphs:
    paragraph.style = document.styles['Normal']
    for run in paragraph.runs:
        run.font.size = Pt(10)
