python word 读取section.page_height参数错误

news 来源：原创 2025/5/25 5:49:22

最近在做报告自动化，发现调用word模板，或程序新建模板，只要调用section.page_height获得的页数据就不正常，

from docx import Document
from docx.shared import Cm, Twipsdoc = Document()
section = doc.sections[0]print("Page Height (Twips):", section.page_height)  # 正常应为 15840
print("Page Height (Cm):", Twips(section.page_height).cm)  # 直接转换为厘米

D:\od172406\venv\Scripts\python.exe D:\od172406\常用文件\调试\sdfdsfaa.py 
Page Height (Twips): 10058400
Page Height (Cm): 17741.9进程已结束，退出代码为 0

换了几个版本的ｐｙｔｈｏｎ＿ｄｏｃｘ，都是如此结果，是什么变了呢

最后只有换思路实现课任务，在此记录，有时间好好研究一下。

from docx import Document
from docx.shared import Cm, Twipsdoc = Document()
section = doc.sections[0]
print(section)
from docx.shared import Cm, Pt
# 设置页面高度为29.7厘米（A4纸的高度）
section.page_height = Cm(29.7)
print("Page Height (Twips):", section.page_height)  # 正常应为 15840
print("Page Height (Cm):", Twips(section.page_height).cm)  # 直接转换为厘米

结果:

D:\od172406\venv\Scripts\python.exe D:\od172406\常用文件\调试\sdfdsfaa.py
<docx.section.Section object at 0x0000021D756B9D30>
Page Height (Twips): 10692130
Page Height (Cm): 18859.729305555556

进程已结束，退出代码为 0

有空研究，查清了原因，版本升级后单位变了

from docx import Document
from docx.shared import Cm, Twipsdoc = Document()
section = doc.sections[0]
print(section)
from docx.shared import Cm, Pt
# 设置页面高度为29.7厘米（A4纸的高度）
print("Page Height (Emus):", section.page_height)  # 正常应为 15840
section.page_height = Cm(29.7)
print("Page Height Emus):", section.page_height)  # 正常应为 15840
print("Page Height (Twips):", section.page_height/635)  # 正常应为 15840
print("Page Height (Cm):", section.page_height/Cm(1.0))  # 直接转换为厘米
print('cm',Cm(1.0))
print('ccc,',section.page_height/Cm(1.0))
