convert("input.docx")
convert("input.docx", "output.pdf")
convert("my_docx_folder/")
如果只是转换一个文档，我们就没有必要用Python了。下面的程序是批量转换指定目录下的 Word 文档。
import os
import glob
from pathlib import Path
# 指定转换目录
path = os.getcwd() + '/'
p = Path(path)
files=list(p.glob("**/*.docx"))
for file in files:
convert(file,f"{file}.pdf")
