如何在python-docx中减少段落之间的空间

Question

[试图用下面的代码在python-docx中减小段落之间的间距，但是将格式应用于该段落时，最后一段会缩小，但各段之间的行不会减少。

我在link 1和link 2处找到了一些示例，但他们不理解xml部分无法获得所需的结果。

我需要您的帮助，以通过python减小段落之间的间距，但不通过word文件进行设置。

from docx import Document
from docx.shared import Inches
from docx.enum.style import WD_STYLE_TYPE
from docx.shared import Pt


document = Document()

document.add_heading('THIS IS MY HEADER WANT TO UNDERLINE IT')


paragraph = document.add_paragraph('THIS IS MY FIRST PARAGRAPH ')
paragraph = document.add_paragraph('THIS IS SECOND PARAGRAPH')
paragraph = document.add_paragraph('SPACING BETWEEN EACH SHOULD BE DECREASED')

paragraph_format = paragraph.paragraph_format
paragraph_format.line_spacing = Pt(3)
paragraph_format.space_after = Pt(5)


print("document created")

document.save('demo.docx')

Answer 1

如果您检查生成的Word文件，您可以按照声明的方式精确地查看您的代码。最后一段-您唯一将格式应用于的段-行距为3pt，后跟5pt；其他所有段落均以默认格式显示。

所以python-docx正常工作，并且如果您的输出错误，那是因为您的代码错误。

首先，我强烈建议您不要将行距设置为3 pt；我认为您很困惑，因为它“无法正常工作”，而您打算设置space_before。其次，确保将格式应用于all段落，而不仅仅是最后一段：

from docx import Document
from docx.shared import Pt

document = Document()

document.add_heading('THIS IS MY HEADER WANT TO UNDERLINE IT')

paragraph = document.add_paragraph('THIS IS MY FIRST PARAGRAPH ')
paragraph.paragraph_format.space_before = Pt(3)
paragraph.paragraph_format.space_after = Pt(5)

paragraph = document.add_paragraph('THIS IS SECOND PARAGRAPH')
paragraph.paragraph_format.space_before = Pt(3)
paragraph.paragraph_format.space_after = Pt(5)

paragraph = document.add_paragraph('SPACING BETWEEN EACH SHOULD BE DECREASED')
paragraph.paragraph_format.space_before = Pt(3)
# no need to set space_after because there is no text after this

print("document created")
document.save('demo.docx')

这将导致文档的所有三个文本段落在其之前有3磅的多余空间，在其后有5磅（并带有规则的前导）。
