利用python实现Word文档与PDF文档的格式转化（提取PDF文本内容），实现PDF文件的合并、拆分，PDF页面旋转以及PDF页面增加水印的完整版代码实现

好的，下面是这些功能的完整版代码实现，包括异常处理和一些额外的功能：

    except Exception as e:
        print("Word文档转换为PDF文档失败：", e)

# 定义转化PDF文档为Word文档的函数

            for page in range(pdf_reader.getNumPages()):
                page_obj = pdf_reader.getPage(page)
                text += page_obj.extractText()
            return text
    except Exception as e:
        print("提取PDF文本内容失败：", e)

# 定义合并PDF文件的函数
def merge_pdf_files(input_paths, output_path):
    try:
        pdf_writer = PdfFileWriter()
        for path in input_paths:
            with open(path, 'rb') as f:

# 定义拆分PDF文件的函数
def split_pdf_file(input_path, output_folder):
    try:
        with open(input_path, 'rb') as f:
            pdf_reader = PdfFileReader(f)

                pdf_writer.addPage(pdf_reader.getPage(page))
                output_path = os.path.join(output_folder, f"page{page}.pdf")
                with open(output_path, 'wb') as out_f:
                    pdf_writer.write(out_f)
        print("拆分PDF文件成功！")
    except Exception as e:
        print("拆分PDF文件失败：", e)

# 定义旋转PDF页面的函数
def rotate_pdf_pages(input_path, output_path, clockwise=True):
    try:
        with open(input_path, 'rb') as f:
            pdf_reader = PdfFileReader(f)
            pdf_writer = PdfFileWriter()
            for page in range(pdf_reader.getNumPages()):
                pdf_page = pdf_reader.getPage(page)
                if clockwise:
                    pdf_page.rotateClockwise(90)
                else:
                    pdf_page.rotateCounterClockwise(90)
                pdf_writer.addPage(pdf_page)
        with open(output_path, 'wb') as out_f:
            pdf_writer.write(out_f)
        print("旋转PDF页面成功！")
    except Exception as e:
        print("旋转PDF页面失败：", e)

# 定义给PDF页面增加水印的函数
def add_watermark_to_pdf(input_path, output_path, watermark_path):
    try:
        watermark = PdfFileReader(open(watermark_path, 'rb')).getPage(0)
        with open(input_path, 'rb') as f:
            pdf_reader = PdfFileReader(f)
            pdf_writer = PdfFileWriter()
            for page in range(pdf_reader.getNumPages()):
                pdf_page = pdf_reader.getPage(page)
                pdf_page.mergePage(watermark)
                pdf_writer.addPage(pdf_page)
        with open(output_path, 'wb') as out_f:
            pdf_writer.write(out_f)
        print("给PDF页面增加水印成功！")
    except Exception as e:
        print("给PDF页面增加水印失败：", e)
