## 场景 ##

PyPDF 2是一个纯python PDF库，能够分割、合并、裁剪和转换PDF文件的页面。它还可以向PDF文件中添加自定义数据、查看选项和密码。它可以从PDF检索文本和元数据，还可以将整个文件合并在一起。

PyPDF 2 1.26.0文档：

## 实现 ##

使用pip 安装pypddf2

新建merged.pdf有两页

新建pdfSplit.py要与pdf在同一目录下。

from PyPDF2 import PdfFileReader, PdfFileWriter
    
    def split(path, name_of_split):
        pdf = PdfFileReader(path)
        for page in range(pdf.getNumPages()):
            pdf_writer = PdfFileWriter()
            pdf_writer.addPage(pdf.getPage(page))
    
            output = f'{name_of_split}{page}.pdf'
            with open(output, 'wb') as output_pdf:
                pdf_writer.write(output_pdf)
    
    if __name__ == '__main__':
        path = 'merged.pdf'
        split(path, 'NO')

运行

可见已经被分隔成两个pdf了。
