Python3; Docx;用word doc替换文本会修改段落后的间距-如何避免或改回？

Question

我有一些函数可以用新字符串成功替换.docx文件中的特定字符串（在段落和表中）。

所有带有函数替换部分的东西都很好用。但是，当我替换段落中的字符串时，“段落后的间距”值会更改。我希望间距保持不变，或者我希望能够在替换发生后将间距改回其原始格式。

我不熟悉docx，所以也许这只是我错过的简单解决方案？

在阅读了Docx文档的更多内容和一些测试之后，解决此问题的方法很简单。

def clear_paragraph(self, paragraph):
    p_element = paragraph._p
    p_child_elements = [elm for elm in p_element.iterchildren()]
    for child_element in p_child_elements:
        p_element.remove(child_element)


def paragraph_replace(self, search, replace, x):
    searchre = re.compile(search)
    for paragraph in self.paragraphs:
        paragraph_text = paragraph.text
        if paragraph_text:
            if searchre.search(paragraph_text):
                clear_paragraph(self, paragraph)
                para = paragraph.add_run(re.sub(search, replace, paragraph_text))
                para.font.size = Pt(10)
                paragraph.paragraph_format.space_after=Pt(0)
                if x is 2:
                    para.bold = True
                else:
                    para.bold = False
                paragraph.paragraph_format.line_spacing = 1.0
    return paragraph


def table_replace(self, text_value, replace):
    result = False
    tbl_regex = re.compile(text_value)
    for table in self.tables:
        for row in table.rows:
            for cell in row.cells:
                paragraphs = cell.paragraphs
                for paragraph in paragraphs:
                    for run in paragraph.runs:
                        font = run.font
                        font.size=Pt(10)
                if cell.text:
                    if tbl_regex.search(cell.text):
                        cell.text = replace
                        result = True
    return result

我在paragraph_replace函数中添加了x参数，因为我希望文档的第一行加粗。现在，通过对代码进行这些简单的添加即可解决我所有的问题。
