使用pypdf2将文件夹中的所有pdf文件合并到一个pdf中

import PyPDF2

def merge_pdfs(folder_path, output_path):
    pdf_writer = PyPDF2.PdfFileWriter()
    for filename in os.listdir(folder_path):
        if filename.endswith(".pdf"):
            file_path = os.path.join(folder_path, filename)
            with open(file_path, "rb") as pdf_file:
                pdf_reader = PyPDF2.PdfFileReader(pdf_file)
                for page_num in range(pdf_reader.getNumPages()):
                    page = pdf_reader.getPage(page_num)
                    pdf_writer.addPage(page)
    with open(output_path, "wb") as merged_pdf:
        pdf_writer.write(merged_pdf)

merge_pdfs("文件夹路径", "合并后的pdf路径")
