如何使用 python docx 保留所有 styles 和对齐方式克隆/复制.docx 文件

Question

I want to clone docx file with all of its styles and alignments. This is my code:

import docx
from docx import Document

doc = docx.Document('my_word_file.docx')
allText = []
for docpara in doc.paragraphs:
    allText.append((docpara.text).replace('a' ,'s')

mydoc = docx.Document()
mydoc.add_paragraph(allText)
mydoc.save("cloned.docx")

So I am fixing some mistakes and file is saving, but without styles or tabs or enters. How to keep changes and stylings too?

I think that the way is to write your own function to copy the text and style of each paragraph. Here is a first implementation of what you could do:

from docx import Document

def copy_paragraph(output_doc, paragraph):

    output_paragraph = output_doc.add_paragraph()
    # Alignment data of whole paragraph
    output_paragraph.paragraph_format.alignment = paragraph.paragraph_format.alignment
    for row in paragraph.runs:
        output_row = output_paragraph.add_run(row.text)
        # Font data
        output_row.style.name = row.style.name
        # Size of font data
        output_row.font.size = row.font.size
        # Bold data
        output_row.bold = row.bold
        # Italic data
        output_row.italic = row.italic
        # Underline data
        output_row.underline = row.underline
        # Color data
        output_row.font.color.rgb = row.font.color.rgb
    
doc = Document('my_word_file.docx')
mydoc = Document()
for paragraph in doc.paragraphs:
    copy_paragraph(mydoc, paragraph)
mydoc.save("cloned.docx")

I don't exclude that there may be other parameters that need to be copied (for example the highlighting of the text, etc.). In this case I suggest you to do some tests and consult the docx documentation that is pretty well written.
