我想使用 Python 将此 HTML 文件转换为 PDF。 我有一个使用 wkhtmltopdf 包的选项，但我每次都必须使用命令行运行它。 在不妨碍我的代码流程的情况下执行此操作的最佳方法是什么？

解决方法

  1. 安装pdfkit包

     pip install pdfkit

  2. 安装 wkhtmltopdf https://wkhtmltopdf.org/downloads.html

  3. PDF 到当前文件夹中的 HTML

    import pdfkit
import glob

    3.1 设置 wkhtmltopdf 可执行文件路径

    config = pdfkit.configuration(wkhtmltopdf='C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf.exe')

    3.2 转换当前文件夹下的所有html文件

    for file in glob.glob('./*.html'):
    pdfkit.from_file(file,file[:-4]+'.pdf',configuration=config)
