我试图使用Python的Python docx模块更改多个段落的格式。在from docx import Document

from docx.shared import Pt

from docx.shared import Inches

from docx.enum.text import WD_PARAGRAPH_ALIGNMENT

from docx.enum.section import WD_ORIENTATION

from content import report_content, provinces, report_date, introduction, intro_content

alignment_dict = {'justify': WD_PARAGRAPH_ALIGNMENT.JUSTIFY,

'center': WD_PARAGRAPH_ALIGNMENT.CENTER,

'centre': WD_PARAGRAPH_ALIGNMENT.CENTER,

'right': WD_PARAGRAPH_ALIGNMENT.RIGHT,

'left': WD_PARAGRAPH_ALIGNMENT.LEFT}

orientation_dict = {'portrait': WD_ORIENTATION.PORTRAIT,

'landscape': WD_ORIENTATION.LANDSCAPE}

document = Document()

def change_orientation(orientation='portrait', set_left_margin=1.0, set_right_margin=1.0):

section = document.sections[-1]

new_width, new_height = section.page_height, section.page_width

section.orientation = orientation_dict[orientation]

section.page_width = new_width

section.page_height = new_height

section.left_margin = Inches(set_left_margin)

section.right_margin = Inches(set_right_margin)

def add_logo(path, align):

document.add_picture(path, width=Inches(4.5), height=Inches(1.5))

last_paragraph = document.paragraphs[-1]

last_paragraph.alignment = alignment_dict[align]

def add_content(content, space_after, font_name='Arial', font_size=11, line_spacing=0, space_before=0,

align='justify', keep_together=True, keep_with_next=False, page_break_before=False,

widow_control=False, set_bold=False, set_italic=False, set_underline=False, set_all_caps=False):

paragraph = document.add_paragraph(content)

style = document.styles['Normal']

font = style.font

font.name = font_name

font.size = Pt(font_size)

font.bold = set_bold

font.italic = set_italic

font.all_caps = set_all_caps

font.underline = set_underline

paragraph_format = paragraph.paragraph_format

paragraph_format.alignment = alignment_dict.get(align.lower())

paragraph_format.space_before = Pt(space_before)

paragraph_format.space_after = Pt(space_after)

paragraph_format.line_spacing = line_spacing

paragraph_format.keep_together = keep_together

paragraph_format.keep_with_next = keep_with_next

paragraph_format.page_break_before = page_break_before

paragraph_format.widow_control = widow_control

def create_numbered_list():

pass

def add_subheading(subheading, level):

document.add_heading(subheading, level)

change_orientation(orientation='landscape', set_left_margin=0.5, set_right_margin=0.5)

add_logo('logo.png', 'center')

add_content(report_content, align='Center', space_before=40, space_after=20, line_spacing=1, font_name='Arial',

set_bold=True, set_all_caps=True)

add_content(provinces, align='Center', space_before=20, space_after=20, line_spacing=1, font_name='Arial',

set_bold=True, set_all_caps=True)

add_content(report_date, align='Center', space_before=20, space_after=20, line_spacing=1, font_name='Arial',

set_bold=True, set_all_caps=True)

document.add_page_break()

add_subheading(introduction, level=1)

add_content(intro_content, space_after=20, space_before=20)

document.save('demo.docx')

问题是，每次我通过add_content方法向新段落块添加格式时，旧块的格式将更改为当前块的格式。在

为什么我不能保留格式，为什么要重置为最新块的格式？在
