這篇文章主要為大家詳細(xì)介紹了如何使用python編寫一個批量轉(zhuǎn)換word文檔為pdf文件的工具,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以了解下

一、安裝 python-docx 和 comtypes 庫

在windows命令行窗口執(zhí)行如下代碼：

pip install python-docx
pip install comtypes

C:\Users\wgx58>pip install python-docx
Collecting python-docx
  Using cached python_docx-1.2.0-py3-none-any.whl.metadata (2.0 kB)
Requirement already satisfied: lxml>=3.1.0 in c:\python\lib\site-packages (from python-docx) (6.0.2)
Requirement already satisfied: typing_extensions>=4.9.0 in c:\python\lib\site-packages (from python-docx) (4.15.0)
Using cached python_docx-1.2.0-py3-none-any.whl (252 kB)
Installing collected packages: python-docx
Successfully installed python-docx-1.2.0

C:\Users\wgx58>pip install comtypes
Collecting comtypes

二、程序代碼
