如何在多个文件夹上运行python来创建pdf？

import os
import pdfkit

def convert_folder_to_pdf(folder_path, output_path):
    options = {
        'page-size': 'A4',
        'margin-top': '0mm',
        'margin-right': '0mm',
        'margin-bottom': '0mm',
        'margin-left': '0mm'
    }
    
    files = []
    
    for root, dirs, filenames in os.walk(folder_path):
        for filename in filenames:
            files.append(os.path.join(root, filename))
    
    pdfkit.from_file(files, output_path, options=options)

# 调用函数来将多个文件夹转换为PDF
convert_folder_to_pdf('/path/to/folder1', '/path/to/output1.pdf')
convert_folder_to_pdf('/path/to/folder2', '/path/to/output2.pdf')
