是否有可能以编程方式"链接"多个PDF文件,最好是从命令行？

import PyPDF2

def merge_pdfs(pdf_list, output_path):
    merger = PyPDF2.PdfFileMerger()
    for pdf in pdf_list:
        merger.append(pdf)
    with open(output_path, 'wb') as f:
        merger.write(f)

pdf_list = ['file1.pdf', 'file2.pdf', 'file3.pdf']
output_path = 'merged_file.pdf'
merge_pdfs(pdf_list, output_path)
